all axis tick labels with the same digits

pietro — Wed, 29 Jul 2009 10:55:04 -0400

How can i have axis tick labels with the same digit? instead [0 0.05 0.1 0.15 0.2] i would like [0.00 0.05 0.10 0.15 0.20]
thank you in advance

Hi Pietro, How about

x=[0 0.05 0.1 0.15 0.2];
y=3*x;
plot(x,y)
set(gca,'xticklabel',{'0.00' '0.05' '0.10' '0.15' '0.20'});

i have too many and different graphs to do like this. Isn't there a function or a axis property?

Unfortunately, no. A pet peeve of mine as well; there's no way to set a
format string for the automagically-generated numeric ticklabel values
and the only way to manually set them is as an array of strings.

Seems like they original coders would have at least had the sense to use
a fixed-width format but they didn't and the annoying and ugly "feature"
has never been fixed since the big bang day of handle graphics.... :(

Maybe put in the feature request again--I did 10 years or more ago but
I've no longer a supported version.

Since I'm guessing you're objecting to the manual way Wayne constructed the
tick label cell array, you can automate the formatting of the labels if the
format you want is possible using the formatting specification in SPRINTF:

x=[0 0.05 0.1 0.15 0.2];
y=3*x;
plot(x,y)
set(gca, 'XTick', x, 'XTickLabel', sprintf('%0.2f|', x));

Which brings up the "pet peeve #27" noted above (I came back to post
this additional response as above which I intended to do but got too
wrapped up in the moment... :) ) --

Why can't the user have the ability to set that format or at least why
doesn't presentation graphics have enough internal sense to make a
neater-looking choice than the default? Seems (and has always seemed)
so obvious a minor little detail that would be so beneficial...

I still think should submit enhancement request. When I've made such
submittals w/o a currently supported license they've pretty much gotten
the brush off afaict...

I agree that this is a feature I've always wanted. Manually setting labels is a huge pain, especially if you plan to zoom, pan, change axis limits, etc. I've written a function, tick2text, that allows you to assign a formatting string to ticks (and to do more slightly complicated formatting, like adding TeX strings) by changing them to text objects:

http://www.mathworks.com/matlabcentral/fileexchange/16003

However, this method is a bit limited in that I find myself having to work around manual changes to the axis. For example:

plot(rand(1,5));
tick2text(gca, 'xformat', '%.2f');
set(gca, 'xlim', [0 10]); % Ticks are wrong
zoom(1); % Now ticks are good again

Also, as I have it written write now, you have to fudge around with the buffer variables to figure out where ticks should be located with respect to your axes if you're using subplots.

Having built-in support for formatting would be very nice.

Good to have the file exchange workaround.

Did you submit an enhancement request???

I could try again, but I'm virtually positive I'd get same "you're
version is no longer under maintenance agreement, but if you'll spend
several thousand dollars to update, we might consider it" response I've
gotten previously.

I'm totaly agree with all of you. I've just submit a function called ADDAXES, which I would like it to work with

a) LOG scale
b) exponential ticks (like in [1 2 3 4] x 10^3)
c) LATEX TickLabels interpreter
d) minor grid ticks

but it is not possible, because there isn't handle for the axes TICKS, the little exponential text, and there is no way to get the minor-ticks (neither in 'linear' or 'log' scale).

Besides, Kelly Kearney is correct a workaround with the ZOOM and PAN functions should be made to update the ticks with the 'ActionPostCallback' functions, which (as far as I have tried) does not work correctly with the

e) Double-click (for zoom out)

Anyway, you can get the ADDAXES function at
