Changelog for v0.2.1

New features:

• More features for plotting!
  • PlotData type for storing plot data.

  // A PlotData holds the data required for plotting.
  //
  // If you want to plot an arbitrary function, leave Df and Columns as nil.
  // Otherwise, populate Df and Columns, and leave Function as "".
  type PlotData struct {
    // Df is the DataFrame object you would like to plot.
    Df *DataFrame
  
    // Columns are the columns in Df that you want to plot. Usually, it's a pair of columns [xcol, ycol].
    // If you want to create a bar graph or a histogram, you can add more columns.
    Columns []string
  
    // Function is an arbitrary function such as sin(x) or an equation of the line of best fit.
    Function string
  
    // Opts are options such as `using` or `with`. `set` is passed in as an argument for other plotting functions.
    Opts []GnuplotOpt
  }

  • PlotN can be used to plot several graphs at once.
  • Fit can be used to fit an arbitrary function to your PlotData object.
  • Options added: with, via

Changes

• Plot is no longer a struct method for DataFrame. Instead, it is a standalone function that accepts PlotData objects.

Bug fixes

• Commands with set are properly parsed without omitting semicolons.
• Double quotes are no longer dropped unexpectedly.
