Suppress exponential formatting in figure ticks

问题

Tick labels for ticks bigger than about 10\'000, get formatted to 1x10^4 for example. Whereas the exponential part appears above the corresponding axes. This misbehavior has been well described on on matlab central as well, but without a solution.

Thanks for your help.

The \'quick trick\'

set(gca, \'YTickLabel\',get(gca,\'YTick\'))

did not work when applied to bar3, as can be seen on the following figure.

One way to get better control over tick labels, and to avoid the exponential formatting, is to use TICK2TEXT from the File Exchange.

Here's an example:

y = cool(7); %# define some data
ah = axes; %# create new axes and remember handle
bar3(ah,y*1E6,'detached'); %# create a 3D bar plot
tick2text(ah, 'ztickoffset' ,-1.15,'zformat', '%5.0f', 'axis','z') %# fix the tick labels

EDIT

According to this technical solution page, the recommended way of formatting the tick labels is this (you can use any of the number formatting functions like NUM2STR, SPRINTF, MAT2STR, or any other..)

y = cool(7);
bar(y(:,1)*1e6)
set(gca, 'YTickMode','manual')
set(gca, 'YTickLabel',num2str(get(gca,'YTick')'))

However there seems to be a bug when it comes to the Z-axis (the labels are correctly formatted, but the exponential multiplier is still showing for some reason!)

y = cool(7);
bar3(y*1e6, 'detached')
set(gca, 'ZTickMode','manual')
set(gca, 'ZTickLabel',num2str(get(gca,'ZTick')'))

Finally, there's another workaround where we replace the tick labels with text objects (see this technical solution page as reference):

y = cool(7);
bar3(y*1e6, 'detached')
offset = 0.25; Xl=get(gca,'XLim'); Yl=get(gca,'YLim'); Zt=get(gca,'ZTick');
t = text(Xl(ones(size(Zt))),Yl(ones(size(Zt)))-offset,Zt, num2str(Zt')); %#'
set(t, 'HorizontalAlignment','right', 'VerticalAlignment','Middle')
set(gca, 'ZTickLabel','')

One other trick you can try is to scale your data before you plot it, then scale the tick labels to make it appear that it is plotted on a different scale. You can use the function LOG10 to help you automatically compute an appropriate scale factor based on your plotted values. Assuming you have your data in variables x and y, you can try this:

scale = 10^floor(log10(max(y)));  %# Compute a scaling factor
plot(x,y./scale);                 %# Plot the scaled data
yTicks = get(gca,'YTick');        %# Get the current tick values
set(gca,'YTickLabel',num2str(scale.*yTicks(:),'%.2f'));  %# Change the labels
