adjusting of axis X

Hi,

I have two row vetctors

a=[1.1 1.8 2.3 3.1 4.5 5.7 6.1 7];
b=[2 5 3 8 9 1 5 2];
plot(a,b)

When I make a plot, there arent values 1.1 1.8 2.3 3.1 4.5 5.7 6.1 7 on the axis X but there are 1 2 3 4 5 6 7. Is it possible to dispaly 1.1 1.8 2.3 3.1 4.5 5.7 6.1 7 on the axis X?

Thank you.

Yes it is!

First you need to make a vector b with the labels:

b=arrayfun(@(x)num2str(x),a,'UniformOutput',false);

Then,

set(gca,'XTick',a,'XTickLabel',b);

should do the trick. If you have the handle of the axis, just replace gca with that handle.

Setting the XTicks is enough:

set(gca, 'XTick', a);

Then Matlab creates the correct labels automatically.
