[Nplot-devel] obtaining xy coordinates on mousedown event

[<DHe...@ao...>]

Bartek,

Looks like the code you are looking for is in the Nplot  library file:
Windows.PlotSurface2D.cs in the DoMouseMove function. 
Look  for "if ( coordinates_.Active )" - the code you need is after the "if".

I  tried this:
If you create a MouseClick event for your plotsurface instance  and add the
following code:

Point here =  new Point(e.X, e.Y);
double x =  plotSurface.PhysicalXAxis1Cache.PhysicalToWorld(here,
true);
double y =  plotSurface.PhysicalYAxis1Cache.PhysicalToWorld(here,
true);

The x  & y should be the coordinates you are looking for. 


Did you get  the source code for Nplot to compile?

Hello!

Cant find solution to my problem..
When displaying  plot with showcoordinates property set to 'true' i can see
coordinates next  to mouse cursor. The problem is I don't know how to assign
current x/y coord  to a variable. Any ideas would be appreciated!
