Heatmap of 2D plot
显示 更早的评论
I have 5 seconds data of a continuous signal of frequency 512 Hz. I need to get a heatmap of this .
I have refered this https://stackoverflow.com/questions/23356219/plotting-many-lines-as-a-heatmap. I need a similiar plot with my data. Can I get some help with the code please.
I've attached the data as a .mat file.

Attach your data into a mat file or a text file. Copying from here is a headache job.

t=[1/512:1/512:5]';
z = zeros(size(t));
col = amp; % This is the color, vary with amp in this case.
surface([t t],[amp amp],[z z],[col col],...
'facecol','no',...
'edgecol','interp',...
'linew',2);
