Hello everyone,
I'm trying to export a simple graph to svg format, but I'm facing some
issues.
My graph should contain a series of points and three infinitelines.
The problem is that when I export the plot to svg the infinitelines are
exported as lines long just 1 unit and the axis labels overlap with the
axes itself, as you can see in the picture attached to this message.
The version of pyqtgraph I'm currently using is 0.12.3
