contour legend

[Ra]

hello,

I am plotting a contour plot from two different columns of a data set.

data set:

317.816 0.0 1.002 0.999
317.816 0.1 0.993 0.989
317.816 0.2 0.963 0.959
317.816 0.3 0.913 0.910
317.816 0.4 0.844 0.841
317.816 0.5 0.754 0.751

317.816 0.0 1.001 0.998
317.816 0.1 0.993 0.989
317.816 0.2 0.963 0.959
317.816 0.3 0.913 0.911
317.816 0.4 0.847 0.842
317.816 0.5 0.756 0.753

317.816 0.0 1.02 1.00
317.816 0.1 1.01 0.98
317.816 0.2 0.99 0.96
317.816 0.3 0.94 0.90
317.816 0.4 0.87 0.85
317.816 0.5 0.78 0.76

I am using the following command:

set contour
unset surface
set cntrparam levels incremental 0.75,0.04,1.06
splot 'mass-e-tau.out' u 1:2:3 w l lw 2 ti 'stable','mass-e-
tau.out' u 1:2:4 w l

Now I want the legend to show different values for third & fourth
columns. The 'set cntrparam' command assigns the same legend range
values for both the columns: How do I tell gnuplot that for column 3
in splot command display a different legend range than in column 4 ??

Thanks

By not saying you want something else. I.e. instead of 'levels
incremental', use 'levels auto'.

Thanks....I did 'set cntrparam levels auto' and I still get the same
legend for both the columns.

That's not terribly surprising --- they have practically the same data
ranges.
