How to plot an overlay curve on the figure attached here.

Hello,

The code for the attached/copied figure is

figure, p = pcolor(b,a,c); p.EdgeColor = 'none'; axis ij; ylim([500 2500]); colorbar; title('abc');

ylabel('Time (ms)'); colormap(jet); grid on

I want to plot a straight line or a curve between (showing relation) a vs. c at x axis where b = 6000. Suppose the curve a vs c has same dimension like the data plotted here as p = pcolor(b,a,c);. How can I plot here.

Use

hold on

then plot the graph.

plot(x,y)

@Kevin Holly thanks, but I want to plot a vs c at some particular value of b, then I can I add here

hold on

plot(a,c) but how to add d value/ position at x axis?

@Nisar Ahmed I'm not entirely sure what you are asking.

Are you trying to plot this?

plot(a,c(6000,:))

This would plot the values along the vertical line shown below.

figure
p = pcolor(b,a,c);
p.EdgeColor = 'none';
axis ij; ylim([500 2500]);
colorbar;
title('abc');
ylabel('Time (ms)');
colormap(jet);
grid on

hold on

xline(6000)

@Kevin Holly Thanks,

I ploted first by using hold on and then by adding some distance on x axis. just like

hold on

plot(b+2393.598,a);
