Decimals in labels on an axis of a QChart[View]

[ibkv]

I have a QLineSeries/QChart displayed in a QChartView. Even though the points I've added are whole numbers, the display graph shows decimals point along the X/Y axes. How do I turn off the decimals points, i.e., specify 0 decimals?

You can use format specifiers, have a look at the following example from Qt documentation.

  QChartView *chartView = new QChartView;
  QLineSeries *series = new QLineSeries;
  // ...
  chartView->chart()->addSeries(series);

  QValueAxis *axisX = new QValueAxis;
  axisX->setRange(10, 20.5);
  axisX->setTickCount(10);
  axisX->setLabelFormat("%.2f");
  chartView->chart()->setAxisX(axisX, series);
