|
35 | 35 | \brief The QAreaSeries class is used for making area charts. |
|
36 | 36 | |
|
37 | 37 | An area series is used to show quantitative data. It is based on line series, in the way that |
|
38 | 38 | the area between the boundary lines is emphasized with color. Since the area series is based on |
|
39 | 39 | line series, QAreaSeries constructor needs a QLineSeries instance, which defines "upper" |
|
40 | 40 | boundary of the area. The area chart is drawn using the bottom of the plot area as the "lower" |
|
41 | 41 | boundary by default. Instead of the bottom of the plot area, the "lower" boundary can be |
|
42 | 42 | specified by another line. In that case QAreaSeries should be initialized with two QLineSeries |
|
43 | 43 | instances. Please note that the terms "upper" and "lower" boundary can be misleading in cases |
|
44 | 44 | where the "lower" boundary has bigger values than the "upper" one. The main point is that the |
|
45 | 45 | area between these two boundary lines will be filled. |
|
46 | 46 | |
|
47 | 47 | See the \l {AreaChart Example} {area chart example} to learn how to create a simple area chart. |
