This might sound like a dumb question, but, I have a line+symbol x-y-y graph, i.e. two measurement results plotted versus one independent variable. The problem is that I am missing one data point in one of the y variables, so, I would like Origin to draw the lines between all adjacent points for each y. However, since I am missing one data point in one of the y's the graph is split in two separate parts. How can i avoid that?
You can control it in the Plot Details dialog at the graph page level ("Format: Page Properties" menu). Choose the "Display" tab, and turn ON the "Connect line across Missing Data" check box. See the screenshot:
