Qt commercial charts provide APIs for the following types of charts:

  • Candlestick chart
  • Polar chart

The following axis types are supported by the QCharts

  • Value axis
  • Category axis
  • Bar category axis
  • Date-Time axis
  • Logarithmic axis

QCharts can be bound to the following ways to the application

QLineSeries *lineSeries = new QLineSeries();

lineSeries->add(0, 9);

lineSeries->add(1, 3);

view->chart()->addSeries(lineSeries);

view->chart()->createDefaultAxes();

QCharts can also be added to the QML as shown below:

import QtQuick 2.0
import QtCharts 2.0

ChartView {

width: 640

height: 480

antialiasing: true

PieSeries {

id: pieSeries

PieSlice {

label: “Success”

value: 94.9

}

PieSlice {

label: “Failure”

value: 5.1

}

}

}
