How can I change the position of the line on a mixed line & bar chart?


Posted by Martin at 18:22 on Tuesday 29th October 2024 [link]
Hi - I'm generating a graph showing state of charge (SoC)and charge points on a solar battery system.
The charge points (half hour slots) are correctly timed but the accompanying line is offset to the middle of each slot.
Is there any way to shift the line half a period to the left so that it matches the charge slot?
I'm using version 6.1.7

You can mess with the margins of the Line chart and reduce the left margin and increase the right margin.

If you're using the CombinedChart class you should do this after the call to the draw function. Like this example shows:

Is this what you meant?
