Dear List,
I would like to define a new second plot inside a first plot using the
axes command.
But I need the position and size do be defined not by the relative
figure coordinates
but by data coordinates.
I have found the following trick :
ax = gca()
f = gcf()
x,y = ax.transData.transform([x,y])/f.transFigure.transform([1,1])
a = axes([x,y,dy,dy])
However, if the position is now ok, the size (dx,dy) is still on
relative figure coordiate.
Ok, I could think a bit more and find how its possible to transform it,
but I would
like to ask the list if there is an easier way to do that.
By the way, why do I have to divide by f.transFigure.transform([1,1]) ?
I expected that ax.transData.transform did return already normalized
values.
Thanks in advance.
yves
