Hi Hannes, The yvalue does not exist. It is not needed to plot the curve. Indeed, the plot is based on the geometric locus, it depends on a mobile point on a line and dependent point, here a point whose coordinates are computed by the block of code. See its implementation in the ckass DrGeoSketch. It is a kind of user side implementation, not part of the core Dr. Geo model:
To compute by yourself the yvalue, you
will need the method above to return the pen point aswell.
You can edit it so it returns a 2array
with both the locus and the pen.
