9 9 We begin by creating a simple line series and a chart object.
10 10 \snippet ../examples/customchart/main.cpp 1
11 11
12 12 Let the customization begin. First we customize the series and the chart's title and background.
13 13 \snippet ../examples/customchart/main.cpp 2
14 14
15 15 Then we customize the axes.
16 16 \snippet ../examples/customchart/main.cpp 3
17 17
18 And the axis label values and ranges.
18 And the axis label values and ranges. Once the axes are ready we set them to be used by the chart.
19 19 \snippet ../examples/customchart/main.cpp 4
20 20
21 21 Finally we create a view containing the chart.
22 22 \snippet ../examples/customchart/main.cpp 5
23 23
24 24 Now we are ready to show the chart on a main window.
25 25 \snippet ../examples/customchart/main.cpp 6
