The status bar shows the current pointer position on canvas. If user clicks on 
the curve KmPlot makes the pointer got locked to the curve and the status bar 
shows the curve coordinates only (including the roots). It is enough to read 
these coordinates to get the impression about the curve.

On the other hand, it is enough to right-click on canvas to understand if the 
pointer is close to some curve. If there is a curve near the pointer position, 
KmPlot shows its context menu which can be read by the screen reader.

Hope this helps.
