[Gnuplot-info] splot xyz zerr

[Patrick D. <pd...@gm...>]

Hello,

I used to use gnuplot for ploting and fitting y (x) function.
I now need to plot and fit 2d functions.
I cannot find the equivalent of 
splot 'file' u 1:2:3:4 w zerr
and
fit function (x,y) file u 1:2:3:4 w zerr
and
fit z=f(x,y) file u 1:2:3:4:5:6 w xyzerr

Is it not possible?

Thank for your help.
