6 | \brief QtCommercial Chart series API for showing scatter series. |

|
9 | |||
10 | Example on how to create a chart with scatter series: |
|
10 | The scatter data is displayed as a collection of points on the chart. Each point determines the position on the horizontal axis | |
11 | \snippet ../example/scatter/main.cpp 1 |
|
11 | and the vertical axis. | |
12 |
|
12 | |||
13 | The example code would result the following: |
|
13 | \image scatterchart.png | |
14 |
|
14 | |||
15 | \image scatter_example1.jpg |
|
15 | Creating basic scatter chart is simple: | |
16 |
|
16 | \code | ||
17 | To customize the graphical representation of the series, you can modify pen, brush, shape and |
|
17 | QScatterSeries* series = new QScatterSeries(); | |
18 | size of the marker items. For example: |
|
18 | series->add(0, 6); | |
19 |
|
19 | series->add(2, 4); | ||
20 | \snippet ../example/scatter/main.cpp 3 |
|
20 | ... | |
21 |
|
21 | chartView->addSeries(series); | ||
22 | Would present your scatter markers as big rectangles with opaque, uglyish green outlines and |
|
22 | \endcode | |
23 | opaque red filling instead of the beatiful markers defined by the chart's theme: |
