"send current view to workspace" does not export dataObject for zoomed figure window

[Johann Krauter]

The plot feature to send the current dataObject to workspace does not work with following plot properties:

• keepAspectRatio: True
• yAxisFlipped: True
• reduced figure window so that the image width limits the scale

itomQwtPlot.cpp line 1150, 1152:

• m_dataObjPlane->getPhysToPix2D(yInterval.maxValue(), yd1, validY1, xInterval.maxValue(), xd1, validX1);
• returns validY0 and validY1 als False
• line 1173 returns with empty dataObject
• dataobj.cpp line 2667 sets “isInsideImageY” to False, because phyiscal value is negativ.

yInterval.maxValue() is negativ

This bug is fixed in the designerPlugins repository. Commit: https://bitbucket.org/itom/designerplugins/commits/125218080d87341416dc84a13c2d2f3a4fb7f6e1

QwtInterval allows that the maxValue is smaller than the minValue. This is the case for an inverted axis. However, such an interval is not valid, such that the contains method
returns false. To overcome this, the interval has to be normalized first.
