Then in the button’s actionPerformed event, copy the datasets from the button to the chart. Set the datasets up by copy/paste in each property’s dataset editor. (Set the chart the way you want, then copy its config datasets to the corresponding button.) The actionPerformed events would look something like this: ec = e…
