Using octave-2.0.9 and gnuplot 3.6 beta I often want to turn of the
key or legend.I am able to do so with the following command
octave:89> plot(1:10,";;")
However I also get the message
warning: empty matrix found in matrix list near line 38, column 25
when I do this
I looked in __pltopt__ and I see the following line
else
if (isempty (key_title)) # needs this to avoid empty matrix warning.
key_title = char;
else
I added the following to the bottom of the __pltopt__.m
if (set_key)
if (isempty (key_title)) # needs this to avoid empty matrix warning.
fmt = strcat (fmt, " ", TITLE, ' "" ');
else
fmt = strcat (fmt, " ", TITLE, ' "', key_title, '" ');
endif
or by diff
mips {snh} 67: diff __pltopt__.m
/every/software/octave/share/octave/2.0.9/m/plot/__pltopt__.m
253,257c253
< if (isempty (key_title)) # needs this to avoid empty matrix warning.
< fmt = strcat (fmt, " ", TITLE, ' "" ');
< else
< fmt = strcat (fmt, " ", TITLE, ' "', key_title, '" ');
< endif
---
> fmt = strcat (fmt, " ", TITLE, ' "', key_title, '" ');
With this change the warning goes away.
Is there an easier way to do this?
Thanks
Steve
