MATLAB: Dynamic y-tick label

MATLABplotytickyticklabelzoom

It have a way to save the y-tick to be dynamic and decide what will be the label format. In default is show 5 number, i want to show 6 number so 1.23456 and 1.23457 will not be both 1.2345. and the same for 12345.6, show the number and not 1.2345 (10^4 in top).

because i use a lot zoom in and zoom out, i cannot use a fix YTickLabel.

Hi Yona,

what you can do is to add a callback to your zoom function, i.e.,

h = zoom(fig);
set(h, 'ActionPostCallback', @ZoomCallback)

where in ZoomCallback.m you do the formatting of the YTickLabels according to the current YTick.

MATLAB: How to create a uniform y-tick interval in subplots

Something like this works. Note that you'll have some challenges because most of your y values are very small, so it might not look quite like you'd expect.

p1 = rand([50,1])*5.5-1.1;
p2 = rand([50,1])*3.5e-6 - 3e-6;
p3 = rand([50,1])*0.5e-6 + 3.8e-6;
p4 = rand([50,1])*4.1e-7 - 3e-7;
p5 = rand([50,1])*0.2e-6 - 3.45e-6;
subplot(5,1,1)
plot(p1)
yval = ylim(gca);
set(gca,'YTick',linspace(yval(1),yval(2),5),"YTickLabel",round(linspace(yval(1),yval(2),5)))
 
subplot(5,1,2)
plot(p2)
yval = ylim(gca);
set(gca,'YTick',linspace(yval(1),yval(2),5),"YTickLabel",round(linspace(yval(1),yval(2),5),6))
subplot(5,1,3)
plot(p3)
yval = ylim(gca);
set(gca,'YTick',linspace(yval(1),yval(2),5),"YTickLabel",round(linspace(yval(1),yval(2),5),6))
subplot(5,1,4)
plot(p4)
yval = ylim(gca);
set(gca,'YTick',linspace(yval(1),yval(2),5),"YTickLabel",round(linspace(yval(1),yval(2),5),7))
subplot(5,1,5)
plot(p5)
yval = ylim(gca);
set(gca,'YTick',linspace(yval(1),yval(2),5),"YTickLabel",round(linspace(yval(1),yval(2),5),6))

MATLAB: Fixed point numbers on plot axes

Hi,

you could do the following:

ytick = get(gca, 'ytick');
yticklabel =strread(sprintf('%.1f;', ytick), '%s', 'delimiter', ';')
set(gca,'yticklabel', ytick)
