Hi,
The code for the valueChanged event in InfLineLabel
(http://www.pyqtgraph.org/documentation/_modules/pyqtgraph/graphicsItems/InfiniteLine.html#InfiniteLine)
uses the setText method inherited from TextItem
(http://www.pyqtgraph.org/documentation/graphicsItems/textitem.html#pyqtgraph.TextItem.setText).
I see two possible options.
1. If you just want to set the size and colour of the label, then try using
the setFont and setColor methods, something like
OrderLine.label.setFont(....) and OrderLine.label.setColor(...), but you'll
need to look up the PyQt documents for usage, as these wrap the underlying
Qt methods.
2. Do a dirty hack on the code, and change the setText to setHtml in the
valueChanged method of InfLineLabel. Not ideal, but might work.
