Hello,
I have a data file created by an C++ Programm which creates the lines of the data file by an operation inside an loop
where the entries of the gsl_vector x are doubles and my_f(x,par) is a double depending on x.
I would like to produce a colour plot with x1 and x2 on the axes and show my_f(x,par) via the color of plot. There are some points x where my_f(x,par) produces an Ignore value (1e+300 in this case) and I don't want data points to be plotted which lead to my_f = Ignore value.
In a 2D plot of my_f over sqrt(x1^2+x2^2) I achieve this with
How can I achieve this? At first there was only one << endl in my code, but that gave me the error that i need more then one Isoline. So I entered the second << endl as the Isolines are sperated by a blank line.
My current Gnuplot Scrit is
This produces a grid with the correct ranges of x and y axes and a colour scale for my_f but with nothing in the plot window as shown in the attached pdf.
Thanks in advance.
