Detailed Description

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

wxString mpLayer::GetName (  )  const [inline, inherited]

Get layer name.

Returns:
Name

Definition at line 170 of file mathplot.h.

00170 { return m_name; }

const wxPen& mpLayer::GetPen (  )  const [inline, inherited]

Get pen set for this layer.

Returns:
Pen

Definition at line 180 of file mathplot.h.

00180 { return m_pen;  }

virtual bool mpScaleY::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 394 of file mathplot.h.

00394 { return FALSE; }

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

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

Implements mpLayer.
