[GNC] Net Worth Linechart report issue

[Lipp F.]

 GnuCash 3.10 on Windows.

The  Net Worth Linechart report is not properly positioned on the canvas.

- when displayed in GnuCash about 15% of the canvas is not used on the
right side part of the canvas and the left side of the chart is missing.
- when exported and opened in a browser the opposite happens, the left side
is missing and 15% right side not utilized.

This is only happening for high resolution charts - one year / daily as an
example.  Low resolution charts,  one year / monthly as an example, seem to
be working fine.
