Dygraph to add an annotation to

Either numeric or date value indicating where to place the annotation. For date value, this should be of class POSIXct or convertible to POSIXct.

Text to overlay on the chart at the location of x

Additional tooltip text to display on mouse hover

Width (in pixels) of the annotation flag.

Height (in pixels) of the annotation flag.

CSS class to use for styling the annotation.

Height of the tick mark (in pixels) connecting the point to its flag or icon.

If true, attach annotations to the x-axis, rather than to actual points.

JavaScript function to call when an annotation is clicked.

JavaScript function to call when the mouse hovers over an annotation.

JavaScript function to call when the mouse exits an annotation.

JavaScript function to call when an annotation is double clicked.

Series to attach the annotation to. By default, the last series defined using dySeries.

Dygraph to add an axis definition to

Axis name ('x', 'y', or 'y2')

Label to display for axis (defaults to none).

Explicitly set the vertical range of the graph to c(low, high). This may be set on a per-axis basis to define each y-axis separately. If either limit is unspecified, it will be calculated automatically (e.g. c(NULL, 30) to automatically calculate just the lower bound).

When set for the y-axis or x-axis, the graph shows that axis in log scale. Any values less than or equal to zero are not displayed. Showing log scale with ranges that go below zero will result in an unviewable graph. Not compatible with showZero. connectSeparatedPoints is ignored. This is ignored for date-based x-axes.

This lets you specify an arbitrary JavaScript function to generate tick marks on an axis. The tick marks are an array of (value, label) pairs. The built-in functions go to great lengths to choose good tick marks so, if you set this option, you'll most likely want to call one of them and modify the result. See dygraph-tickers.js and the dygraphs documentation for additional details).

Add the specified amount of extra space (in pixels) around the value range to ensure points at the edges remain visible.

Width of the div which contains the y-axis label. Since the y-axis label appears rotated 90 degrees, this actually affects the height of its div.

Height of the x-axis label, in pixels. This also controls the default font size of the x-axis label. If you style the label on your own, this controls how much space is set aside below the chart for the x-axis label's div.

Height, in pixels, of the x-axis. If not set explicitly, this is computed based on axisLabelFontSize and axisTickSize.

Color of the x- and y-axis lines. Accepts any value which the HTML canvas strokeStyle attribute understands, e.g. 'black' or 'rgb(0, 100, 255)'.

Thickness (in pixels) of the x- and y-axis lines.

Number of pixels to require between each x- and y-label. Larger values will yield a sparser axis with fewer ticks. Defaults to 50 (x-axis) or 30 (y-axes).

Color for x- and y-axis labels. This is a CSS color string. This may also be set globally using dyOptions.

Size of the font (in pixels) to use in the axis labels, both x- and y-axis. This may also be set globally using dyOptions.

Width, in pixels, of the axis labels

JavaScript function to call to format the tick values that appear along an axis (see the dygraphs documentation for additional details).

JavaScript function to call to provide a custom display format for the values displayed on mouseover (see the dygraphs documentation for additional details).

Whether to display grid lines in the chart.

The color of the grid lines.

Thickness (in pixels) of the grid lines drawn under the chart.

Only valid for y and y2, has no effect on x: This option defines whether the y axes should align their ticks or if they should be independent. Possible combinations: 1.) y=true, y2=false (default): y is the primary axis and the y2 ticks are aligned to the the ones of y. (only 1 grid) 2.) y=false, y2=true: y2 is the primary axis and the y ticks are aligned to the the ones of y2. (only 1 grid) 3.) y=true, y2=true: Both axis are independent and have their own ticks. (2 grids) 4.) y=false, y2=false: Invalid configuration causes an error.

Dygraph to add CSS styles to

Path to css file to be used for styling textual elements of the graph.

Dygraph to add callbacks to

A function to call when the canvas is clicked.

When set, this callback gets called every time the dygraph is drawn. This includes the initial draw, after zooming and repeatedly while panning.

When set, this callback gets called every time a new point is highlighted.

A function to call when a data point is clicked. and the point that was clicked.

When set, this callback gets called before the chart is drawn.

When set, this callback gets called every time the user stops highlighting any point by mousing out of the graph.

A function to call when the zoom window is changed (either by zooming in or out).

Draw a custom item when a point is highlighted. Default is a small dot matching the series color. This method should constrain drawing to within pointSize pixels from (cx, cy)

Draw a custom item when drawPoints is enabled. Default is a small dot matching the series color. This method should constrain drawing to within pointSize pixels from (cx, cy).

JavaScript function to call when an annotation is clicked. This can also be specified on a per-annotation basis.

(deprecated) See argument x.

Dygraph to add a series definition to

character vector of the series within data set. If no name is specified then series are bound to implicitly based on their order within the underlying time series object. This parameter can also be a character vector of length 3 that specifies a set of input column names to use as the lower, value, and upper for a series with a shaded bar drawn around it.

Labels to display for series (uses name if no label defined)

Color for series. These can be of the form "#AABBCC" or "rgb(255,100,200)" or "yellow", etc. If not specified then the global colors option (typically based on equally-spaced points around a color wheel).

Y-axis to associate the series with ("y" or "y2")

When set, display the graph as a step plot instead of a line plot.

When set, display the graph as a stem plot instead of a line plot.

Should the area underneath the graph be filled? This option is not compatible with error bars.

Draw a small dot at each point, in addition to a line going through the point. This makes the individual data points easier to see, but can increase visual clutter in the chart.

The size of the dot to draw on each point in pixels. A dot is always drawn when a point is "isolated", i.e. there is a missing point on either side of it. This also controls the size of those dots.

The shape of the dot to draw. Can be one of the following: "dot" (default), "triangle", "square", "diamond", "pentagon", "hexagon", "circle", "star", "plus" or "ex".

The width of the lines connecting data points. This can be used to increase the contrast or some graphs.

A predefined stroke pattern type ("dotted", "dashed", or "dotdash") or a custom pattern array where the even index is a draw and odd is a space in pixels. If NULL then it draws a solid line. The array should have an even length as any odd length array could be expressed as a smaller even length array.

Draw a border around graph lines to make crossing lines more easily distinguishable. Useful for graphs with many lines.

Color for the line border used if strokeBorderWidth is set.

A function which plots the series group. See the dygraphs documentation for additional details on plotting functions.

Dygraph to configure highlighting behavior for.

The size in pixels of the dot drawn over highlighted points.

Fade the background while highlighting series. 1=fully visible background (disable fading), 0=hidden background (show highlighted series only).

When set, the options from this list are applied to the series closest to the mouse pointer for interactive highlighting. Example: list(strokeWidth = 3). See the documentation on dySeries for additional details on options that can be set.

Whether to hide the highlighting effects when the mouse leaves the chart area. Note that this also affects the hiding of the dyLegend on mouse out.

Dygraph to configure legend options for.

When to display the legend. Specify "always" to always show the legend. Specify "onmouseover" to only display it when a user mouses over the chart. Specify "follow" to have the legend show as overlay to the chart which follows the mouse. The default behavior is "auto", which results in "always" when more than one series is plotted and "onmouseover" when only a single series is plotted.

Width (in pixels) of the div which shows the legend.

Show zero value labels in the legend.

Show data labels in an external div, rather than on the graph. This value should be a div element id.

Put a <br/> between lines in the label string. Often used in conjunction with labelsDiv.

Whether to hide the legend when the mouse leaves the chart area. This option applies when show is set to "onmouseover". Note that this also affects the hiding of the dyHighlight on mouse out.

Dygraph to add limit line to

Numeric position of limit.

Label for limit. Defaults to blank.

Location for label (left or right).

Color of limit line. This can be of the form "#AABBCC" or "rgb(255,100,200)" or "yellow". Defaults to black.

Dygraph to add options to

If set, stack series on top of one another rather than drawing them independently. The first series specified in the input data will wind up on top of the chart and the last will be on bottom.

Should the area underneath the graph be filled? This option is not compatible with error bars. This option can also be set on a per-series basis.

Transparency for filled regions of the plot. A value of 0.0 means that the fill will not be drawn, whereas a value of 1.0 means that the fill will be as dark as the line of the series itself.

When set, display the graph as a step plot instead of a line plot. This option can also be set on a per-series basis.

When set, display the graph as a stem plot instead of a line plot. This option can also be set on a per-series basis.

Draw a small dot at each point, in addition to a line going through the point. This makes the individual data points easier to see, but can increase visual clutter in the chart. This option can also be set on a per-series basis.

The size of the dot to draw on each point in pixels. A dot is always drawn when a point is "isolated", i.e. there is a missing point on either side of it. This also controls the size of those dots. This option can also be set on a per-series basis.

The shape of the dot to draw. Can be one of the following: "dot" (default), "triangle", "square", "diamond", "pentagon", "hexagon", "circle", "star", "plus" or "ex". This option can also be set on a per-series basis.

Draw points at the edges of gaps in the data. This improves visibility of small data segments or other data irregularities.

Usually, when dygraphs encounters a missing value in a data series, it interprets this as a gap and draws it as such. If, instead, the missing values represents an x-value for which only a different series has data, then you'll want to connect the dots by setting this to true.

The width of the lines connecting data points. This can be used to increase the contrast or some graphs. This option can also be set on a per-series basis.

A custom pattern array where the even index is a draw and odd is a space in pixels. If null then it draws a solid line. The array should have a even length as any odd length array could be expressed as a smaller even length array. This is used to create dashed lines. This option can also be set on a per-series basis.

Draw a border around graph lines to make crossing lines more easily distinguishable. Useful for graphs with many lines. This option can also be set on a per-series basis.

Color for the line border used if strokeBorderWidth is set. This option can also be set on a per-series basis.

A function (or array of functions) which plot each data series on the chart. May also be set on a per-series basis. See the dygraphs documentation for additional details on plotting functions.

Character vector of colors for the data series. These can be of the form "#AABBCC" or "rgb(255,100,200)" or "yellow", etc. If not specified, equally-spaced points around a color wheel are used. This option can also be set on a per-series basis. Note that in both global and per-series specification of custom colors you must provide a color for all series being displayed. Note also that global and per-series color specification cannot be mixed.

If custom colors are not specified, value of the data series colors, as in hue/saturation/value (0.0-1.0, default 0.5).

If custom colors are not specified, saturation of the automatically-generated data series colors (0.0-1.0, default 0.5).

Whether to draw the x-axis. Setting this to false also prevents x-axis ticks from being drawn and reclaims the space for the chart grid/lines.

Whether to draw the y-axis. Setting this to false also prevents y-axis ticks from being drawn and reclaims the space for the chart grid/lines.

Usually, dygraphs will use the range of the data plus some padding to set the range of the y-axis. If this option is set, the y-axis will always include zero, typically as the lowest value. This can be used to avoid exaggerating the variance in the data.

When set, draw the X axis at the Y=0 position and the Y axis at the X=0 position if those positions are inside the graph's visible area. Otherwise, draw the axes at the bottom or left graph edge as usual.

When set the graph shows the y-axis in log scale. Any values less than or equal to zero are not displayed.

The spacing between axis labels and tick marks.

Color of the x- and y-axis lines. Accepts any value which the HTML canvas strokeStyle attribute understands, e.g. 'black' or 'rgb(0, 100, 255)'. This can also be set on a per-axis basis.

Thickness (in pixels) of the x- and y-axis lines. This can also be set on a per-axis basis.

Color for x- and y-axis labels. This is a CSS color string. This may also be set on a per-axis basis.

Size of the font (in pixels) to use in the axis labels, both x- and y-axis. This may also be set on a per-axis basis.

Width (in pixels) of the containing divs for x- and y-axis labels.

Whether to display grid lines in the chart. This may be set on a per-axis basis to define the visibility of each axis' grid separately. Defaults to TRUE for x and y, and FALSE for y2.

The color of the grid lines. This option can also be set on a per-series basis.

Thickness (in pixels) of the grid lines drawn under the chart. This option can also be set on a per-series basis.

Height of the chart title, in pixels. This also controls the default font size of the title. If you style the title on your own, this controls how much space is set aside above the chart for the title's div.

Number of pixels to leave blank at the right edge of the Dygraph. This makes it easier to highlight the right-most data point.

Unless it's run in scientific mode (see the sigFigs option), dygraphs displays numbers with digitsAfterDecimal digits after the decimal point. Trailing zeros are not displayed, so with a value of 2 you'll get '0', '0.1', '0.12', '123.45' but not '123.456' (it will be rounded to '123.46'). Numbers with absolute value less than 0.1^digitsAfterDecimal (i.e. those which would show up as '0.00') will be displayed in scientific notation.

Show K/M/B for thousands/millions/billions on y-axis.

Show k/M/G for kilo/Mega/Giga on y-axis. This is different than labelsKMB in that it uses base 2, not 10.

Show date/time labels according to UTC (instead of local time). Note that this option cannot is incompatible with useDataTimezone (you must use one or the other).

When displaying numbers in normal (not scientific) mode, large numbers will be displayed with many trailing zeros (e.g. 100000000 instead of 1e9). This can lead to unwieldy y-axis labels. If there are more than maxNumberWidth digits to the left of the decimal in a number, dygraphs will switch to scientific notation, even when not operating in scientific mode. If you'd like to see all those digits, set this to something large, like 20 or 30.

By default, dygraphs displays numbers with a fixed number of digits after the decimal point. If you'd prefer to have a fixed number of significant figures, set this option to that number of significant figures. A value of 2, for instance, would cause 1 to be display as 1.0 and 1234 to be displayed as 1.23e+3.

A value representing the farthest a graph may be panned, in percent of the display. For example, a value of 0.1 means that the graph can only be panned 10 null means no bounds.

Set this option to animate the transition between zoom windows. Applies to programmatic and interactive zooms. Note that if you also set a drawCallback, it will be called several times on each zoom. If you set a zoomCallback, it will only be called after the animation is complete.

Set this option to automatically disable touch events on the Y axis for mobile devices (since this interferes with swiping/scrolling on mobile devices).

Set this option to log timing information. The value of the option will be logged along with the timing, so that you can distinguish multiple dygraphs on the same page.

Whether to use the time zone of the underlying xts object for display. Defaults to FALSE which uses the time zone of the client workstation. Note that this option is incompatible with labelsUTC (you must use one or other other).

Whether to retain the user's current date window (zoom level) when updating an existing dygraph with new data and/or options.

Set this option to disable click and drag zooming.
