I have three variables day, time and z2 and i plot using imagesc. Below are the data information:
data information:
day 1*1420 double(each number is equal to 6 hours)
time 1*3001 double (this case has -300:300 with interval of 0.2)
z2 1420*3001 double
Later I converted the weeks segments into date by using below code.
fig=figure(ii);
h1=subplot(3,1,1);
imagesc(time,day,z2);
colormap(jet)
YTickStr = char(datetime('10/10/2018', 'InputFormat', 'dd/MM/yy', 'Format', 'dd/MM/yy') + hours(day*6));
set(gca, 'YTick', 1:lengday, 'YTickLabel', YTickStr);
xlim([-100 100]);
If i do not use any interval, ticks label are so difficult to read as below and I cant read any thing
Later, I change the interval with 1:500:lengday and it starts from 1JAN which i exected to start from 10/10/18.
How can I modify the code so that it gives me the interval based on Ytrickstr?
here is my failed attemt which gives me the first 5 values from YTickStr.
yval = ylim(gca);
set(gca,'YTick',linspace(yval(1),yval(2),5),'YTickLabel', YTickStr)
YTickStr files is like this
10/10/18
10/10/18
10/10/18
11/10/18
11/10/18
11/10/18

Thank you very much
