Hi everbody,
I have a plot of 31 data points. However, instead of labeling the x-axis is (1:1:31), I want to set it to (-6:1:24). How can I do that?
Best

solved much simpler by going
figure,plot(-6:24,1:31)
because you're setting the x and y plot pairs.

set(gca,'XTick',-6:24,'XTickLabel',-6:24);
Note that that command is doing two things in one line. It defining tick mark positions, and also relabeling them.

Thank you for the quick response but somehow I can't get it to work.
Take for example:
plot(1:1:31);
set(gca,'XTick',-6:24,'XTickLabel',-6:24);
The x-axis is somehow messed up

figure
plot(1:1:31);
set(gca,'XLim',[-6 24],'XTick',-6:24,'XTickLabel',-6:24);
This fixes my solution, but I think the other answers here are actually what you wanted, aligning your 31 data points with the x-axis points -6:24.

Hi. im displaying my data from serial monitor arduino for temperature monitoring. So now it show the temperature vs second on the graph. Is there any command to change the seconds to current time like maybe 12.45 instead of its displaying 200 second.

You have posted this question as an "answer" on a 6-year-old question that is unrelated. Instead, you should post a new question.
