hi all, i create a graph. then select "graph" -> "plot setup" from the menu to add more data to it. i select the boxes for X and Y data to be plotted but when i click "add", my checked Y box gets unchecked and nothing is added to the graph.
You may miss the last step. When you click Add button, you just add the curve in the plot list in fact. If you want to add this curve to graph, please click the triangle button at right corner to expand the bottom panel. You could see the added curve in the plot list, and then click OK button to add it to the graph.
