Defines the full range of a viewport data scale.
In the ChartDirector zooming and scrolling framework, the viewport coordinates are expressed as the visible fractions of the "full data scale". For example, if the "full data scale" is 10 years horizontally, a viewport width of 0.1 means that 1 year of data are visible.
The setFullRange method defines the full range of a data scale and gives it a name. As ChartDirector supports multiple x-axes and y-axes, so there can be multiple data scales with different names. The name can be used in other ChartDirector APIs to convert between the viewport coordinates and data scale (see
WebChartViewer.getValueAtViewPort,
WebChartViewer.getViewPortAtValue), and to configure an
Axis to reflect the visible data scale (see
WebChartViewer.syncLinearAxisWithViewPort,
WebChartViewer.syncLogAxisWithViewPort and
WebChartViewer.syncDateAxisWithViewPort).
