@ -49,8 +49,14 @@ You can further style the plot by e.g. setting:
graph->setFillColor(graphh->getColor().lighter());
// 4.2 make whiskers dashed
graph->setWhiskerLineStyle(Qt::DashLine);
graph->setWhiskerLineColor(graph->getLineColor().darker());
// 4.3 change mean symbol
graph->setSymbolType(JKQTPstar);
graph->setSymbolType(JKQTPFilledStar);
graph->setSymbolFillColor(QColor("silver"));
// 4.4 change median line color
graph->setMedianLineColor(QColor("darkgreen"));
// 4.5 change box width to 75% of distance
graph->setBoxWidth(0.75);
```
The result looks like this:
