|
6 | The example shows how to combine different charts and set the axes. In the example we combine linechart with | |
|
|
7 | barchart and use category axis as common axis for both. | |

|
|
11 | Here we create data for our barseries. | |
|
|
12 | ||
|
|
13 | \snippet ../examples/lineandbar/main.cpp 1 | |
|
|
14 | ||
|
|
15 | We create the barseries and append the sets to it. | |
|
|
16 | First value of each set are gropuped together at first category second value to second category and so on. | |
|
|
17 | ||
|
|
18 | \snippet ../examples/lineandbar/main.cpp 2 | |
|
|
19 | ||
|
|
20 | Then we create lineseries and add data to it. To make data match with barchart we use index as an x-value for our line series, so that | |
|
|
21 | first point is at (0,value) second at (1,value) and so on. | |
|
|
22 | ||
|
|
23 | \snippet ../examples/lineandbar/main.cpp 8 | |
|
|
24 | ||
|
|
25 | Here we create the chart and add both series to it. | |
|
|
26 | ||
|
|
27 | \snippet ../examples/lineandbar/main.cpp 3 | |
|
|
28 | ||
|
|
29 | To make chart show series properly, we have to create custom axes for series. If we don't create custom axes, then each series will get scaled to | |
|
|
30 | use maximum area of the chart (like in single series case) and result will be incorrect. With custom axes we set the range of both series to follow same | |
|
|
31 | axis. For x-axis we use QBarCategoryAxis and for y-axis we use QValuesAxis. | |
|
|
32 | ||
|
|
33 | \snippet ../examples/lineandbar/main.cpp 4 | |
|
|
34 | ||
|
|
35 | And we also want to show the legend. | |
|
|
36 | ||
|
|
37 | \snippet ../examples/lineandbar/main.cpp 5 | |
|
|
38 | ||
|
|
39 | Finally we add the chart onto a view. | |
|
|
40 | ||
|
|
41 | \snippet ../examples/lineandbar/main.cpp 6 | |
|
|
42 | ||
|
|
43 | And it is ready to be shown in a window. | |
