In my work I use variability charts and fit y by X a lot. In most cases there are several groups in a plot. When I create legends for them I can change the font size for the legends but the marker size cannot be changed. This has been an issue for us when we present our results. People constantly complai.n I know that it is possible to change the marker size in Graph builder but it would be a great help to add this feature to other types of graphs.
