Not able to change Line Spacinging
Known issue
When attempting to change the Line spacing under CHART>CHART OPTIONS and Position Scale Tab, Turbo-Chart may hang for a long time when adjusting the Line Spacing value in Chart Options.

The issue is that when you click in the cell, it highlights the value, then as you type in a new value, Turbo-Chart is redrawing grid lines as you’re entering each value.
For example if the chart range location range is from -100 to +80,000, if you start entering any value, Turbo-Chart is attempting to draw grid lines every unit of the first value you type. If you enter 1, it is attempting to draw over 80 thousand grid lines and this is why it appears to be crashing.
There are two workaround to this:
-
Instead of overwriting the entire cell’s value, click again to insert numbers into the cell, then delete. Starting with larger/Left most numbers helps, OR
-
Copy the value you want to use to your clipboard, CTRL+C, from another source (eg. Excel or Notepad) then Paste that value CTRL+V, into the Line Spacing cell.
