Rubber band changed the axis range like silly

[firsnur96]

Hi everyone.
I have a chart. Im using rectangle rubber band for zoom into my chart.
When i zoomed in, my axis range changed with silly numbers.
Is there any way to prevent it?
Also i zoom out with my mouse right clicked, axis get the silly ranges again

Hi,

Can you show the code you are using ?
Can you provide a minimal compilable example that shows this behaviour ?
Which version of Qt are you using ?
On which platform ?

@SGaist Im on ubuntu 18.4 and im using the version 5.15 of qt

here is my code

```
 chart->addAxis(axisX, Qt::AlignBottom);

axisY->setTickCount(1);
axisY->setRange(-2,+2);
chart->addAxis(axisY, Qt::AlignLeft);

chart->legend()->setAlignment(Qt::AlignRight);
chart->legend()->setMarkerShape(QLegend::MarkerShapeCircle);
chartView->setRenderHint(QPainter::Antialiasing);
chartView->setRubberBand(QChartView::RectangleRubberBand);
```

the first photo is before zoom in
the second one is after zoom in with rubber band

The code looks good.

Can you provide a minimal compilable example that shows this behaviour ?

@SGaist I was though screen shots are enough but if you say what kind of example should i show you i will show immediately

@firsnur96 @SGaist means a small application which demonstrates the issue you have, so others can reproduce it.
