How to re-scale the Axises when exporting "Values" from binscatter ??

I am using the h= binscatter(x,y,N) with N=250 to plot my data (figure 1 below). After I created it I extract counts=h.Values to plot the contour(counts) - (figure 2 below).. Thus, I have a question. How to rescale my Axises in contour plot (figure 2) to have the same values as on Figure 1????

Many thanks

Figure 1:

Figure 2 ([M,h]=contourf(counts,5);):

I'm not sure I understand the question. Have you tried this?

xlim([x1 x2])
ylim([y1 y2])

Sorry didnt get what do you mean. I am not very deep in Matlab,

I need to have the same "real" scales in contour plot like I had in binscatter.

When you extract counts from binscatter plot this is the matrix with the size 250 by 250 with the counts number....

What is a "real" scale?

You can have more contour lines in you contour.

x = randn(1e6,1);
y = 2*x + randn(1e6,1);
N=250;
figure()
h = binscatter(x,y,N)
figure()
d=contour(h.Values,N)

I don't think it's a Matlab problem, bur you need to clearly define what you're trying to achieve.

Sorry that was not very precise. Please look on the intital descrtiption with images! Thanks

I understand now.

You can directly change it using

set(gca,'xtick',xmin:.1:xmax)

Alternatively you can create NxN matrices using meshgrid with the values you need and then plot using contourf

[X,Y] = meshgrid(linspace(xmin,xmax,250),linspace(ymin,ymax,250))
figure()
h = binscatter(x,y,N)
figure()
d=contourf(X,Y,h.Values)

Dear Matteo,

thanks for the hint with set(gca,'xtick',xmin:.1:xmax).

I tried to implement it directly but in appears in wrong place and not stretched to the full axis,see image below:
