Printing timesteps over raster data series.

I am running some loops through one raster series, for every timestep I determine a new 'Fodder' raster and I visualize it using 'imagesc' I would like to know if there is any way to plot the current raster and its respective timestep (t=1:2080) to see the evolution of 'Fodder' through time.

Kind regards.

You can use title:

caption = sprintf('Image #%d', k);
title(caption, 'FontSize', 30);

Or you can use text():

text(x, y, caption);

Or you can use the test inserter function in the Computer Vision System Toolbox.

Thanks for your answer, I tried with text, but maybe my question was not clear enough. I would like to add to my graphic series the corresponding timestep tag and that it varies dynamically as a function of time, I am displaying a series of 'Fodder' evolution from t=1:2080. So for the first frame I would like to see '1' for the second '2' and so on, but without stopping the program (like an animation) with one legend or similar showing the current timestep.

Regards.

Finally I used: title(sprintf('Whatever: %i', timestep))

Thanks!

You're welcome. That is what I thought. k is whatever number you want - it can be timestep if that's what you called it. I think usually people use %d for integers and %f for floating point numbers. Personally I usually don't like to embed function calls inside function calls. I think it makes it easier to read, follow, and maintain if they're separate, but that's your choice.
