Re: errorbar plot won't work

[Henry F. Mollet]

octave-2.9.13:7> xx=[1,2,3,4];
octave-2.9.13:8> yy=[10,11,12,13];
octave-2.9.13:9> ey=[1,1.5,2,2.5];
octave-2.9.13:11> errorbar (xx,yy,ey,'~')

Worked for me. To be able to see all four data points I had to then use
octave-2.9.13:14> axis( [0,5,5,20])
and the errorbar plot was redrawn with the new axis scales.
On my eMac using gnuplot-4.2.0/AquaTerm the data points were drawn with blue
+ and the errorbar with blue - and connecting blue line. As expected except
for blue color.
