Unequal tick distribution on axis

Is there a way i can manually set the tick marks of the x axis in a way that they aren't equally distributed?

For the x axis, I need to plot at 101217, 101223, 101229, 110107, 110112, 110121, and 110130. The numbers correspond to yy-mm-dd. This leads to an unclear graph with a jumble of data points in the 100,000 range and a jumble in the 110,000 range.

So, how do i get tick marks at just the above points?

Hi Adrian,

just set the ticks:

set(gca, 'Xtick', [101217 101223 101229])

Or did I misunderstand something?

I have tried that but the problem is that the automatic scaling makes it hard to distinguish between the different dates.

Here is a picture of the graph I created:

I just can't figure out how to make it so the ticks don't have equal spacing between them

Do you really want to plot all your data with such an odd x coordinate system? I would recommend translating your x coordinates to datenumbers, then use datetick to label the axis.

t = [101217, 101223, 101229, 110107, 110112, 110121, 110130];
y = rand(7,1); % some fake data
dn = datenum(num2str(t'), 'yymmdd');
plot(dn, y, 'b.');
datetick('x',25);
