Definition at line 492 of file vtkPlot.h.

◆ GetUnscaledInputBounds()

virtual void vtkPlot::GetUnscaledInputBounds ( double bounds[4] )

inlinevirtual

Provide un-log-scaled bounds for the plot inputs.

This function is analogous to GetBounds() with 2 exceptions:

It will never return log-scaled bounds even when the x- and/or y-axes are log-scaled.
It will always return the bounds along the input axes rather than the output chart coordinates. Thus GetXAxis() returns the axis associated with the first 2 bounds entries and GetYAxis() returns the axis associated with the next 2 bounds entries.

For example, vtkPlotBar's GetBounds() method will swap axis bounds when its orientation is vertical while its GetUnscaledInputBounds() will not swap axis bounds.

This method is provided so user interfaces can determine whether or not to allow log-scaling of a particular vtkAxis.

Subclasses of vtkPlot are responsible for implementing this function to transform input plot data.

The returned bounds are stored as (Xmin, Xmax, Ymin, Ymax).
