How to superimpose a line plot to a colormap created with imagesc?
2 ビュー (過去 30 日間)
I need to write the lines necessary to get the following plot: http://s29.postimg.org/5ed1w5tfb/signalprova.jpg
In have a list of signals, namely from F1 to Fn. Then I computed the moving window correlation between signal F1 with signals F2 up to signal Fn. In above linked plot, the color map displays the moving window correlation and the line displayed is the temporal trend of the plot. I have plot the color map with imagesc . How may I superimpos the plot to the colormap and displaying the y-axis of the plot in the right side?

Have you considered using plotyy() ?
I do not see anything on there that needs to be done with imagesc(). It looks to me like the colored points could be done with scatter(). For example,
numsignal = 5;
corr_taken_at = [1 35 44 80 107]; %x locations the correlation was calculated
corr_values = rand(numsignal, length(corr_taken_at)); %correlation values
[Y, X] = ndgrid(1:numsignal, corr_taken_at);
pointsize = 10;
scatter(X(:), Y(:), pointsize, corr_values(:), 'filled');
This tells scatter() to use the corr_values as the information about which color to use
