r421 | \brief The QAreaSeries class is used for making area charts. | ||
| \mainclass | ||||
|
Titta Heikkala
|
r2754 | An area series is used to show quantitative data. It is based on line series, in the way that | ||
| the area between the boundary lines is emphasized with color. Since the area series is based on | ||||
| line series, QAreaSeries constructor needs a QLineSeries instance, which defines "upper" | ||||
| boundary of the area. The area chart is drawn using the bottom of the plot area as the "lower" | ||||
| boundary by default. Instead of the bottom of the plot area, the "lower" boundary can be | ||||
| specified by another line. In that case QAreaSeries should be initialized with two QLineSeries | ||||
| instances. Please note that the terms "upper" and "lower" boundary can be misleading in cases | ||||
| where the "lower" boundary has bigger values than the "upper" one. The main point is that the | ||||
| area between these two boundary lines will be filled. | ||||
