Possible Fix for Disappearing Lines

Thank you Kubes

Go to the chart properties and reselect the chart background color. Reselect the black in the corner of the color dialog.

Then resave the Color theme by clicking the Save button for the Color Theme. Close the chart property form and resave the workspace. Issue is with the particular color of black used being the special black we use for the paint can color substitution on DYOs. Issue has nothing to do with the chart data. Erasing chart data and starting a chart over just used a different black color for the background that was not our special substitution color.
