Subject: if the y value is out of bounds, make it just a wee bit larger or smaller
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=bb834fb78a6a5d32c9b7c199561ce3c3d7aff609;p=rrdtool-all.git

if the y value is out of bounds, make it just a wee bit larger or smaller
than the bound so that the code can detect this by comparing it with the
bound, but make it so small that it is not visible.
