Remove (from list)
To remove charts from the list at the top right of the main window, highlight them pressing the CTRL key or SHIFT key while clicking on the charts you want to remove. After they are highlighted, press <SHIFT + DEL> together, or select the chart menu or toolbar as shown below:
A dialog will appear asking if you are sure you want to remove the selected charts from the list, click yes if you are sure.
This is not the same as deleting charts, but is akin to "closing" a chart that was open. I didn't want to call this function "Close" because it could have been confused with closing the window / application which is what the Exit routine does.
