Hi,
I have tried Gnuplot mailing list and the newsgroup but didn't get the
help I was looking for. So here my try there.
Given a data file:
######### 3cols.dat #########
0.2846 0.1857 1
0.8283 0.1330 2
0.3306 0.8348 3
0.7961 0.7968 4

I want to plot the 2-D points given by first two columns in a color
given by the their label in the last column. The color doesn't matter,
only that points with a particular label are plotted with the same color.
Here is what I have so far:
set pm3d
set palette rgb 33,13,10
set view map
set cbrange [1:4]
ssplot "3cols.dat" with points palette pt 9
However, a knowledgeable soul at the Gnuplot mailing list has informed
me that using pm3d is a bad idea (the above command spews out warnings
about not enough isosamples) and I should use 'plot' command for this.
But he did not follow that up with a little example.
So, can anyone here give an example using the plot command for this
purpose? This is on Debian testing, Gnuplot 4.2.
thanks,
->HS
