The same problem exists with QCPItemLine

[SBGit-2019]

Thank you again for the report. It is indeed a bug. It is because not all public fields are exposed to python. I hoped we would only need method access not field access. But since this is not true we need to expose the public fields also to python. I will look into this.

[SBGit-2019]

Fixed in release 2.1.5

• Access to all QCP public fields. Access now via fields (abc.start) instead of (abc.start()))
• Old style access using abc.get_start() still possible but deprecated

This works now:

infLine.point1.setCoords(50, 0)
infLine.point2.setCoords(50, 1)
