|
28 | 28 | \brief The QAreaSeries class is used for making area charts. |
|
29 | 29 | |
|
30 | 30 | \mainclass |
|
31 | 31 | |
|
32 | 32 | An area chart is used to show quantitative data. It is based on line chart, in the way that area between axis and the line |
|
33 | 33 | is emphasized with color. Since the area chart is based on line chart, QAreaSeries constructor needs QLineSeries instance, |
|
34 | 34 | which defines "upper" boundary of the area. "Lower" boundary is defined by default by axis X. Instead of axis X "lower" boundary can be specified by other line. |
|
35 | 35 | In that case QAreaSeries should be initiated with two QLineSerie instances. Please note terms "upper" and "lower" boundary can be misleading in cases |
|
36 | 36 | where "lower" boundary had bigger values than the "upper" one, however the main point that area between these two boundary lines will be filled. |

|
189 | 189 | |
|
190 | 190 | The pie series defines a pie chart which consists of pie slices which are QPieSlice objects. |
|
191 | 191 | The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices. |
|
192 | 192 | The actual slice size is determined by that relative value. |
|
193 | 193 | |
|
194 | 194 | By default the pie is defined as a full pie but it can be a partial pie. |
|
195 | 195 | This can be done by setting a starting angle and angle span to the series. |
