<![CDATA[Segfault when trying to add a 2nd LineSeries to a Chart]]>Hi, I'm trying to have 2 differents series plotted on the same chart. However, when I try to add the 2nd series the program segfaults and the debugger point to the line chart->domain()->setSize(rect.size()); in the ChartPresenter::updateGeometry function.

Any idea what causes the segault and how I can add the 2nd series?
I know for a fact the data are organized in the same way

However this is inside a Qt file and not inside a class I've made so I don't understand why it's breaking

Verify that chart & chart->domain() are valid/not nullptr, as those would likely be the cause of the SEGFAULT?
