Hello XFormers,

There seems to be a problem with inspecting XYPlot with mouse. After
invoking fl_set_xyplot_inspect(), I try to pick up points on the plot by
clicking the mouse on them. If the points are close to each other, it is
hard to do it - often clicking the mouse exactly over one point
"returns" the other one. One usually has to move the mouse quite a bit
off the point to get it by clicking. I suspect some kind of offset
introduced somehow by the internal routines which moves the origin of
reference system.

For those who would like to test the problem on other machines (I could
find it on Solaris 2.5.1 and Linux/ELF, latest 0.88), here is the
URL containing tarred source plus two data files required:

ftp://sirius.astrouw.edu.pl/pub/msz/xyplot.tar.gz

Untar, "make", invoke by "vartool var.dat". Clicking the mouse on any of
the two XYPlots, prints (to stdout) the data point index and its coords.
Try any of the close points groups.

with best regards,

Michal.
