This option can also be set on a R interface to dygraphs. API docs for the DygraphOptions class from the dygraph library, for the Dart programming language. See the usage documentation linked to from the sidebar for more details. per-axis options Some options make more sense when applied to an entire axis, rather than to individual series. One standard deviation must be specified for each data point. I want to place the legend of a dygraph within a shiny app on the left hand side of the plot (within the dygraph). 43 * 44 * @param {Dygraph} dygraph The chart to which this renderer belongs. How can I Labels You can add labels to a dygraph using the main, ylab and xlab arguments. updateOptions({series:1, strokeWidth:2 }); updates all series with a strokeWidth of 2. R interface to interactive time series plotting using the dygraphs JavaScript library. Contribute to rstudio/dygraphs development by creating an account on GitHub. Interactive out of the box: zoom, pan and mouseover are on by default. </p> Resizes the dygraph. group = NULL, elementId = NULL, width = NULL, height = NULL) Either time series data or numeric data. 45 * @param {HTMLCanvasElement} element The <canvas> DOM <p>Add a horizontal limit line to a dygraph</p> <p>Configure options for the dygraph series legend. Is it possible to use updateOptions to update just one series with a wider strok Trying to have two Y axis with different scales. strokeWidth: the width of the line being drawn (again, you won't normally need this, see above) dygraph: A reference to current dygraph object (useful for calling getOption () and friends) The 42 * renderer simply gets a drawing context. Another significant feature of the dygraphs library is the ability to display high/low bands around data series. Usually, dygraphs will use the range of the data plus some padding to set the range of the y-axis. Please see this pic at first I have a question about my dygraph height and width. This makes the individual data points easier to see, but can increase visual clutter in the chart. If the width/height are specified, Usually, dygraphs will use the range of the data plus some padding to set the range of the y-axis. For the y-axis, this also controls the width of the y-axis. If the width/height are specified, the div will be resized. This is what I Independent Ticks The independentTicks option can be used to determine which axis is primary (and therefore which axis grid lines are aligned with). Height (in pixels) of the annotation flag. CSS class to use for styling the Draw a small dot at each point, in addition to a line going through the point. For instance, the axisLabelFormatter option lets you specify a function for format the labels on Table of contents: R Dygraphs – How to Get Started Deep Dive Into R Dygraphs – Visualize Stock Data R Dygraphs in R Shiny – Build an App From Scratch Summing up R Dygraphs The dygraphs library parses this data (including column headers), resizes its container to a reasonable default, calculates appropriate axis ranges and tick marks and draws the graph. Strong support for high/low This post describes the options offered by the dygraphs package for interactive time series visualization with R. Width (in pixels) of the annotation flag. It doesn't scale when I resize my browser. My problem is that I cannot set the absolute width of the dygraph since the app axisLabelWidth # Width (in pixels) of the containing divs for x- and y-axis labels. If no parameters are specified, resizes to fill the containing div (which has presumably changed size since the dygraph was instantiated. It shows the different chart types available and how to customize them. I successfully run my flexdashboard but the graph is cut. You can use dygraphs within R Markdown documents just like any other R plotting function. If this option is set, the y-axis will always include zero, typically as the lowest value. I'm not really sure what this is a measurement of. You can use dygraphs at the R console, within R Markdown documents, and within Shiny applications. For example: dygraph(discoveries, main = "Important Discoveries", ylab = "Discoveries . For time You can customize the display of axes using the dyOptions function (for global options) and dyAxis function (for per-axis options). This is far more efficient than destroying and re-instantiating a Dygraph, since it doesn't have to reparse the underlying data. Here’s an example that uses both: dyAxis("y", label = "Temp (F)", For date value, this should be of class POSIXct or convertible to POSIXct. Note that for the x-axis, this is independent from pixelsPerLabel, Features Handles huge data sets: dygraphs plots millions of points without getting bogged down. In order to display the secondary axis scale at least I noticed that in initiating a Dygraph object width and height can only be set to pure integers. However, rather than a PNG file being included in your document, the JavaScript required to render your Updating a dygraphs like: g1. The second Y axis scale doesn't show and the data plotted almost entirely off screen.
