# Qt Charts QML Types

The Qt Charts QML API is an intuitive and simple way to show charts in your QML applications.

Use the following QML to create a simple pie chart:

      import QtQuick 2.0
      import QtCharts 2.0

      ChartView {
          width: 400
          height: 300
          theme: ChartView.ChartThemeBrownSand
          antialiasing: true

          PieSeries {
              id: pieSeries
              PieSlice { label: "eaten"; value: 94.9 }
              PieSlice { label: "not yet eaten"; value: 5.1 }
          }
      }

Note: Since Qt Creator 3.0 the project created with Qt Quick Application wizard based on Qt Quick 2 template uses QGuiApplication by default. As Qt Charts utilizes Qt Graphics View Framework for drawing, QApplication must be used. The project created with the wizard is usable with Qt Charts after the QGuiApplication is replaced with QApplication.
