New Functions

  • plotSetFonts eliminates lines of code and makes it easy to set font family, size, and color for the entire plot, subsections of the plot, or combinations of plot features.
  • plotSetMissGap controls whether missing data creates a gap in line plots, making it easier to plot aggregated series and series across different time periods.
  • dfappend allows you to vertically stack data frames, while automatically merging all metadata and maintaining the properties of categorical and string variables.
  • plotSetActiveX and plotSetActiveY conveniently specify which axis settings apply to and makes it easy to customize all plot axes.
  • head and tail create previews of first or last rows of data.
  • New convenience function annotationSetLinePen simplifies customization of line width, color, and style of annotations and can be used in place of annotationSetLineStyle, annotationSetLineColor, and annotationSetLineThickness.
  • annotationSetTextAlign makes it easier to annotate specific plot observations by providing control of text alignment in textboxes.


  • New optional degrees-of-freedom adjustment for vcm and vcx provides one function for creating sample or population variance-covariance.
  • Expanded outerJoin can perform full outer joins which combine dataframes and include unmatched key observations from both tables.
  • Significant speed improvements to the indnv procedure, as well as a new optional argument to reduce computational overhead if data is presorted.
  • Improved automatic tick placements for dates in plotXY and plotTSHF.
  • The miss function with no inputs provides a convenient way to create a scalar missing value.
  • The column input to reshape is now optional and if a -1 is passed in for the row or column input, reshape will infer the other dimension.
  • Added support for specifying text interpreters separately across multiple axes to plotSetTextInterpreter.
  • plotaddtextboxcan now specify the location of the text box relative to its attachment point (i.e. top right, bottom left, etc).

New and Improved Examples

  • plotunemp.e illustrates plotting time series variables with added recession bars from a dataframe using plotXY with formula strings and plotAddVBar.
  • plot_customlayout_1.e shows how to place a histogram count of the data above the x-axis and across from the y-axis.
  • Updated example files to use new functionality:
    • plotadd1.e
    • plotaddci.e
    • plot_bootmean.e
    • plotadderrorbar2.e
    • plotar2.e
    • plotbar.e
    • plotbox_auto.e
    • and more.
