How to set an uneven distribution of xticks?

Hi All,

I have this:

plot([1.244812244389030e+02;1.387135810473820e+02;1.494424738154610e+02;1.508949276807980e+02;1.512359276807980e+02;1.131822169576060e+02;98.110316708229500;87.436364089775600]);
       set(gca,...
            'xtick',[1, 1.15, 1.3, 1.45, 1.75, 1.95, 2.45, 2.95],...
            'xticklabel',{'1' '1.15' '1.3' '1.45' '1.75' '1.95' '2.45' '2.95'});

When plotting the xticks do not fit the actual data points which should be unevenly distributed along the xaxis. Can somebody help?

Many Thanks!!

When I ran your code, the 'XTick' locations were correct. You didn’t supply an x-vector, so MATLAB supplied a default x-vector, that went from 1 to 8, and the 'XTick' values were plotted with respect to that. What x coordinates did you intend to use? Provide them to plot, and the 'XTick' values will plot where you want them to be on the x-axis.

Guessing here but if you wanted your x-vector to be the vector you provided to 'XTick', you get the plot that I believe you want:

plot([1, 1.15, 1.3, 1.45, 1.75, 1.95, 2.45, 2.95], [1.244812244389030e+02;1.387135810473820e+02;1.494424738154610e+02;1.508949276807980e+02;1.512359276807980e+02;1.131822169576060e+02;98.110316708229500;87.436364089775600]);
set(gca, 'xtick',[1, 1.15, 1.3, 1.45, 1.75, 1.95, 2.45, 2.95], 'xticklabel',{'1' '1.15' '1.3' '1.45' '1.75' '1.95' '2.45' '2.95'});

Other than not providing an x-vector to plot, you did everything correctly.
