Dear all,
there is something I didn't get in the new version of cgplot, maybe someone can help me.
After cgerrorplot being replaced by the new "err_" options in cgplot, I suppose to draw error bars with a command like the following:
cgplot, 0.5, 0.5, psym=9, err_yhigh=1., err_ylow=1., xrange=[0.,1.], yrange=[0.,1.]
this is just a naive example, but really in my work I find often error bars that go outside the axis range.
I tried to use noclip=0 to prevent error lines plotted outside the box, but without success.
Is there a solution, or I just have to fix it by hand (i.e., modifying err_ylow or err_yhigh values when they are too large)?
thanks in advance,
iary

You can find an updated version of cgPlot here, with an ERR_CLIP
keyword. Set the keyword to 1 to clip the error bars to the clipping
boundary of the plot.
