here is my code with the figure
But the values of the x axis are not the one i wanted
after reading an answer to a similar question, I wrote this code to replace the ticks by other
xticks([0 50 100 150 200 250])
set(gca,'Xtick',[-100 100 300 500 700 900])
but it changed the scale instead of the values.
How do I get to change the values by the ones I want ?
