Gnuplot with parametric scripts combined with Python scripts

Because the paper needs to use gnuplot mapping, and I like to use Python to generate data, so I studied the next gnuplot with the parameters of the script, so I can generate data at the same time call gnuplot, the implementation of a lot of methods, here I only say this.

1 Reset 2 set term PNG 3 Set Output Output_fname 4 Plot input_fname using 1:2 w LP PT 0 title ' Data '

Above is a simple line chart of the gnuplot script, the parameters are the inside of the Output_fname and Input_fname, the script needs to be called in the command line to specify these two parameters,

Line 23rd through 30 is the execution of the script, which uses Popen to execute the command line.

The effect is as follows:
