Apply rubberband in more than one data series

M.Maric

Hi! I'm doing a graph that shows two data series like this

First I draw the candle graph and I set the rubber band option :

chartview=QChartView(self.candlechart)
chartview.setRubberBand(QChartView.HorizontalRubberBand)

After that I draw the lines over the candle graph without problems but when I zoom the graph using the rubber band...

...the candle graph are zoomed but the lines doesn' t.

Is something that I missing out? Are lines compatible with the rubber band option or I should configure some event?

Thanks!

Hi and welcome to devnet,

How are you painting these lines ?

Hi SGaist , thanks for your welcome... I'm drawing these lines like this

        chartview=QChartView(self.__candlechart)
        chartview.setRubberBand(QChartView.HorizontalRubberBand)
        chartview.setRenderHint(QPainter.Antialiasing)

        lineserie1=QLineSeries()
        for i in self.times:
            lineserie1.append(QPointF(i,random.random()))
        pen = lineserie1.pen()
        pen.setWidth(3)
        pen.setBrush(QBrush(QColor(255,0,0)))
        lineserie1.setPen(pen)

        lineserie2=QLineSeries()
        for i in self.times:
            lineserie2.append(QPointF(i,random.random()))
        pen = lineserie2.pen()
        pen.setWidth(3)
        pen.setBrush(QBrush(QColor(0,0,255)))
        lineserie2.setPen(pen)

        self.__candlechart.addSeries(lineserie1)
        self.__candlechart.addSeries(lineserie2)

If I change the order (I mean add the lines before set rubber band option I got the same result.

Thanks!
