spurious dots on plots

[karlmsmith]

Reported by @AnsleyManke on 22 Sep 2009 18:50 UTC Patrick Brockmann has a couple of times reported a stray dot on plots. I've never been able to replicate it, but in his last report, detailed in

http://dods.ipsl.jussieu.fr/brocksce/ferret_bugs/err620_extradot/

I CAN see it in v6.2 but not in subsequent local executables.

Comment by @AnsleyManke on 22 Sep 2009 18:51 UTC This was fixed along with the fixes to ticket 1663, "if plot axes are re-drawn for an overlay plot, don't re-draw the labels"

ppl/plot/daxis.F, ppl/plot/plotz.F, ppl/plot/pltit.F

Comment by @AnsleyManke on 22 Sep 2009 22:05 UTC HOWEVER, there are extra dots, when starting Ferret in gif mode, when a label is followed by another line. This goes all the way back to the oldest executable I have, Ferret v5.22 (year 2000). See Patrick's other report, http://dods.ipsl.jussieu.fr/brocksce/ferret_bugs/err619_extradot.jnl

The label may be from either a LABEL command, or the automatic labels drawn to form the plot key:

ferret -gif
yes? set win/siz=.3
yes? plot/i=1:50/vlim=-10:10/hlim=-10:60  sin(i/5)
yes? plot/over/vs/line {-4,40},{-5,5}
yes? plot/over/i=1:50  cos(i/5)
yes? frame/file=dot1.gif

> ferret -gif
yes? set win/siz=0.3   
yes? plot/i=1:50/vlim=-10:10/hlim=-10:60  sin(i/5)
yes? label/nouser 1,-0.6,-1,0,0.1, "Hello1"
yes? plot/over/vs/nolab/line/color=3 {-4,40},{-5,5}
yes? frame/file=dot2.gif
