hello, how can I add a legend on a graph to distinguish between graphs plotted (on the same canvas) from different gas files using Garfield++?

like plotting the electron drift velocity in two different gases, for example

You can use the method SetLabels of the class ViewMedium to set the labels of each graph explicitly.
