19 | 19 | Class members \c m_series and \c m_titles are going to store series and related titles. In example we are going to present data as a line chart |

20 | 20 | using QLineSeries , as scatter chart using QScatterSeries, and as a spline chart using QSplineSeries. We create needed instances in constructor of ChartView class. |

22 | 22 | The data series has been populated. To display it on a chart we create QChartView object and add the data series to it. We also set the ranges on both axises, so that our chart is fully visible and there is some excess of space for adding more data points. |

|
8 | 8 | \image chartview_example.jpg |

|
10 | 10 | To replace the line series with a pie series you use the dedicated QPieSeries class: |

|
12 | 12 | \image chartview_example_pie.jpg |

|
14 | 14 | To use a scatter series you use QScatterSeries class: |

|
16 | 16 | \image chartview_example_scatter.jpg |
|
17 | 17 | |
|
18 | 18 | And to show a bar series you use one of the bar series classes, for example QBarChartSeries: |

|
22 | 22 | If you need to give a more professional touch to your chart you can switch from the default |
|
23 | 23 | theme to one of the other themes: |
