The AxisChart class provides an abstract base for every chart view using axis.
The AxisChart class provides the basic functionality for every axis chart view. It is a abstract class and cannot be instancied itself. An Axis chart is a chart using a coordinates system such as LinearChart and RadialChart.
|
protectedvirtual |
Calculates the order in which the series (columns) should be drawn.
For example, in LinearChart, the columns with the type Thistle::Bar will be drawn at first to avoid to mask the others.
Reimplemented in LinearChart.
|
protectedvirtual |
Paint the legend for the given column.
The kind of legend should be defined by each view (linear and radial represent legend differently). The column legend is represented by a square colored with the pen and brush style and the column name.
Reimplemented in LinearChart.
|
protectedvirtual |
Scans values in the model to find the minimum and the maximum.
Returns the width needed to display the Y scale. If the values are greater than zero, the minimum is equal to 0. If the values are less than 0, the maximum is equal to 0. If a value is not a number (undefined, a string, etc.), she's considered as equal to 0.
Implements AbstractChart.
| void setSerieFormat | ( | int | column, |
| SerieFormat | style | ||
| ) |
Sets the given style to the given column.
The style defines the look and feel of a serie.
