Hello, this may be a very simple question, but how would one scale the x-axis in MatLab? I want to have the x-axis start at -190 and end at 200, with increments of 10. I have my input data plotted, i'll attach a figure. If you can help, great!

Below is a copy of my script:

Temp = [100,75,50,25,0,-25,-50,-65,-75,-85,-100,-125,-150,-175];

Impact_Energy = [89.3,88.6,87.6,85.4,82.9,78.9,73.1,66,59.3,47.9,34.3,29.3,27.1,25];

plot(Temp,Impact_Energy,'r*')

title('Impact Energy V. Temperature')

xlabel('Temperature, measured in C')

ylabel('Impact Energy, measured in J')

xlim([-180 110])

ylim([20 90])

在 MATLAB Online 中打开

Temp = [100,75,50,25,0,-25,-50,-65,-75,-85,-100,-125,-150,-175];

Impact_Energy = [89.3,88.6,87.6,85.4,82.9,78.9,73.1,66,59.3,47.9,34.3,29.3,27.1,25];

plot(Temp,Impact_Energy,'r*')
title('Impact Energy V. Temperature') 
xlabel('Temperature, measured in C') 
ylabel('Impact Energy, measured in J')
set(gca, 'XLim', [-190, 200], 'XTick', -190:10:200,...
    'XTickLabel', -190:10:200);

Thank you, this seems to help with the increments. However, would you know why the numbers are looking blurred on the x-axis. It seems to be displaying numbers on top of each other. Please refer to the attachment to see what I am saying. Does this have anything to do with the font-size of the numbers?
