Since Qt 5.7, QtCharts (https://doc.qt.io/qt-5/qtcharts-index.html) is available in the OpenSource version of Qt.
I currently see three possibilities for MitkChart:
- stick to C3js
- use QtChart under the hood of MitkChart
- remove MitkChart and use QtChart alone
We should do a well reflected decision (as we know now all requirements that we need) as soon as possible.
