I have ReImPlot plots that show the dependence of the variable V0, V-1 on sigma (conductivity), chi0, chi-1 on sigma. I have the equations for them fully written in the program, which include common variables that are not changed in the program. If to use short equations (as it was shown above in the program, for example for V0, V1), then ReImPlot will not build the graph correctly, and will build straight lines (that is there will be no dependence between these variables).
How can I pull the actual values of V0 (red line on the graph) and the corresponding sigma value from the graph in some increments (0, 5000, 10000, 15000) (with the increment being the sigma variable itself)?
