 /*!
 \brief QmitkChartWidget is a widget to display various charts based on the javascript chart library C3js. Currently, bar charts, line charts and pie charts are supported.
 * \details Data is added via AddData1D() or AddData2D().\n
 * There can be multiple charts (of the same type) created by calling AddData1D or AddData2D multiple times.\n\n
 * The following chart types are supported:
 * * line chart: http://c3js.org/samples/simple_multiple.html
 * * bar chart: http://c3js.org/samples/chart_bar.html
 * * spline chart: http://c3js.org/samples/chart_spline.html
 * * pie chart: http://c3js.org/samples/chart_pie.html
 * \n Technical details: The javascript code is embedded in a QWebEngineView. The actual js code is implemented in resource\Chart.js.
 * \sa http://c3js.org for further information about the used javaScript library.
 * \warning Pie is significantly different than the other types. Here, the data given by AddData1D is summed. Each entry represents a different category.
