MATLAB: Formatting y axis to exponential format

formatting y axis to exponential format

I have plotted some data using subplot in a 3 by 4 array. The y axis is from 0 to 15000 and the x axis is from 0 to 4. I know by default the plots should be in exponential format, however the first 4 subplots are not but the rest are. Why is this happening? How can I convert the y axis to exponential format? So it reads exponential to 3 decimal points?

ax = gca();
ax.YRuler.Exponent = 3;
ax.YRuler.TickLabelFormat = '%.3f';

There are two possible workarounds:

1) You can set the Y-ticklabels explicity as follows:

x = [ 1 2 3 ];
y = [10000 20000 30000];
plot(x,y)
set(gca,'YTick',y)
set(gca,'XTick',x)
Yvalues = get(gca,'YTick');
set(gca,'YTickLabel',Yvalues);

2) You could also use the SPRINTF function to format your tick labels using the format of your choice. The 'XTickLabel' or 'YTickLabel' property of the axis would then use those strings as tick labels.

x=[1 2 3];
y=[10000 20000 30000];
plot(x,y)
set(gca,'XTickLabel',sprintf('%3.1f|',x))
set(gca,'XTick',x)
set(gca,'YTickLabel',sprintf('%4.1e|',y))
set(gca,'YTick',y)

For more information on the available formats, consult the documentation for the SPRINTF function:
