Getting plot axis to show all tick values

I'm trying messing around with a bit of musical analysis (with the help of the MIR toolbox). I've got a pseudocolor plot showing the relative strengths of each possible chord (A, A#, B.....G# each being either major, minor or seven chord).

Once I have the plot though, it only shows every 5th or 6th value. If I zoom in, it will show up. But I would like to be able to see the entire plot with all values.

I tried changing the fontsize to smaller, but it made no difference.

Any help would be very much appreciated.

Are you using a simple plot-command?

Then you can set your Y-Ticks manually by:

set(gca, 'YTick', [Vector of your custom y-Ticks])

Hope this helps.

I'm using the pcolor command. The setting of axis details is still the same though, the current command looks like this:

yAxis = {'G#7';'G7';'F#7';'F7';'E7';'D#7';'D7';'C#7';'C7';'B7';'A#7';'A7';'G#m';'Gm';'F#m';'Fm';'Em';'D#m';'Dm';'C#m';'Cm';'Bm';'A#m';'Am';'G#M';'GM';'F#M';'FM';'EM';'D#M';'DM';'C#M';'CM';'BM';'A#M';'AM';};

pcolor(out)

set(gca,'YTickLabel', yAxis, 'FontSize', 6);

If I change the YTickLabel command to simply YTick, then I get the following error:

??? Error using ==> set

Conversion to double from cell is not possible.

Ah, okay.

Try this:

yAxis = {'G#7';'G7';'F#7';'F7';'E7';'D#7';'D7';'C#7';'C7';'B7';'A#7';'A7';'G#m';'Gm';'F#m';'Fm';'Em';'D#m';'Dm';'C#m';'Cm';'Bm';'A#m';'Am';'G#M';'GM';'F#M';'FM';'EM';'D#M';'DM';'C#M';'CM';'BM';'A#M';'AM';};

x = 1:10;

plot(x,x+1);

set(gca, 'YLim', [1 length(yAxis)]);

set(gca, 'YTick', [1:length(yAxis)]);

set(gca, 'YTickLabel', yAxis);

That works :) I get all my values on the yaxis this time.

so do you think it's a problem with the pcolor command?

[BF83]

In your first comment you assigned a cell instead of a vector to the 'YTick' and that's the reason for the error message, so there is no problem with the 'pcolor' command.

You can use the lines from above using the 'pcolor' command as well.

Is your problem solved, then?

Worked perfectly. Thanks very much!!
