I am not getting correct plot

To plot a 2D graph you can use "plot()" function. And the "drawnow()" function is just to see the updates immediately on the screen. It will not have any effect on the resulting graph.

And as you can see you are using "p1 range" for the x-axis and the "p1" are from 1.1 to 1.3, but in the given screenshot x range is from 1-10. And coming to y-axis, in the given screenshot there are 5 "LEs", but you are plotting just the 3 "LEs" and those "LEs" values also does not seem to match with screenshot values.

It is just that the x-axis and y-axis values does not seem to be correct. And to plot all the 5 "LEs" you can plot the "LEs" one after the other and can make use of "hold on" to plot all the "LEs" on the same axes.

For more information on "plot()" function you can refer below MathWorks doumentation:

For more information on "drawnow()" you can refer below documentaion:

And for more information on "hold on" please refer:

Hope it helps.
