GetDist GUI

The GetDist Gui can be used to open chains and plot them for quick visualization. It can either open a grid directory (as show above), or a directory containing chain files. Select each chain root name you want to plot to add it to the list box; these can be dragged and dropped to change the order if needed. Then select the parameter names to plot in the checkboxes below. The Gui supports 1D, 2D (line and filled), 3D (select two parameters and "color by"), and triangle and rectangle plots.

To show the gui run python/ This requires the standard python modules to be installed; see the Python readme for how to install and configure. It should run on any platform.

Use the option on the file menu to export as-is a PDF or other image file of the current plot. For better quality (i.e. not formatted for the current window shape) and fine control (e.g. add custom legend text, etc), export the script, edit and then run it separately (see plotting scripts). The Script Preview tab also gives a convenient way to view the script for the current plot, and preview exactly what it will produce when run:

You can also edit and customize the script, or open and play with existing plot scripts.

The Data menu has an option to let you view the parameter statistics (.margestats) and latex tables, convergence stats, and view PCA constraints for selected parameters.

The Options menu allows you to change a settings defining how limits, lines and contours are calculated, and customize plot options. The "Plot module config" option lets you use a different module to define the plotting classes (available by default are getdist.plots and planckStyle).
