Hi Richard,<br>
<br>
If you target QGIS 3, you might also go with a plain QML approach
which is available as of Qt 5.3 which should be available on any
distro where QGIS 3 is shipped.<br>

<br>
QtCharts is built on the same foundation, so you can get to the same
results. It just needs a bit more boilerplate code.<br>

Thanks all for the libs and tips :-)<br>
<br>
@Martin: I will have a look at Qt-graph, I think it is best
to keep<br>
close to our core libs. But not sure if it will soon be
available in<br>
repo's/distro's including the python bindings.<br>
<br>
Besides this I'm doing this as part of a larger QGIS 2.x
plugin, so will<br>
eventually probably have to use both ways.<br>
