Detailed Description

Plot layer implementing a x-scale ruler. The ruler is fixed at Y=0 in the coordinate system. A label is plottet at the bottom-right hand of the ruler. The scale numbering automatically adjusts to view and zoom factor.

Here is the caller graph for this function:

virtual bool mpScaleX::HasBBox (  )  [inline, virtual]

Check whether this layer has a bounding box. This implementation returns FALSE thus making the ruler invisible to the plot layer bounding box calculation by mpWindow.

Reimplemented from mpLayer.

Definition at line 377 of file mathplot.h.

00377 { return FALSE; }

void mpScaleX::Plot ( wxDC &  dc,
mpWindow &  w 
) [virtual]

Layer plot handler. This implementation will plot the ruler adjusted to the visible area.

Implements mpLayer.
