hi , every one , can i find help to do this , thank you

1) how can i make a plot like this ( i need only the plot with the yellow line )

2) if i have a file.fig and i need to integrate it in a script matlab to put it with another figure on the same plot

[dpb]

So, is the figure shown the .fig file content? Or, where did the yellow line shown come from? If you have the figure, what's the problem in retrieving the X|YData from it?

thank you for responding on my questions

i did a mistake when i write , i mean without the yellow line to know only how to design this plot for other problem

i find on internet this commando to upload a figure in a script matlab

h1 = openfig('Fairpartner_AIS[4321].fig','reuse');

but my question how can i design a quadratic scale plot like the figure that i attach it on this page

thank you again for yuor time

have a nice weekend

I do not see a "quadratic scale plot" ?

xlim([-500 500]);
xtick(-500:250:500);
ylim([0 2000]);
ytick(0:250:2000);
xlabel('y-axis [m]');
ylabel('x-axis [m]');

I guess I don't follow what is "a quadratic scale plot" in the sense of the question. You can build that base plot by

hAx=axes;
view([90 90])
hAx.YLim=[-500 500];
hAx.YTick=[-250:250:500];
hAx.XLim=[0 2000];
hAx.XTick=[0:250:2000];
hAx.XDir='reverse';
box on; grid on
xlabel('X')
ylabel('Y')

presuming the x- and y- axes really are reversed and not just labelled in reverse postions as normal.

thank you

XDir reverse would be for high x values down to low x values, which is not the case in this plot.

The x and y axes labels are exchanged

That's a fignewton of the orientation when swap the axes, Walter...then you have to flip XDir to return to the expected direction visually when it's in the normal y-axis location.

Give it a try... :)
