MATLAB: How to change plot from Descending to Ascending

Question

If I have

plot(k,gpa,'r+:',finalArray2,finalArray1);

which forms a descending plot, what can I change to make it an ascending plot?

Answer 1

Maybe something like using sort() to sort your data,

[gpa, sortOrder] = sort(gpa, 'descend');
k = k(sortOrder); % Sort k the same way.

or setting the xdirection to reverse:

ax = gca
ax.YDir = 'reverse';
