Changing Plot Title from variable

Question

0 个投票

How would I change the title of figure based on the value in a cell?

For example: I have my angle, power reading, and exposure values in cells (219X1 doubles)

For each image I create, how can I make the title correspond to the values in the cells like this:

Image1 has title: Angle = angle(1), Power = power(1), Exposure = exposure(1)

Image2 has title: Angle = angle(2), Power = power(s), Exposure = exposure(2)

Additional notes: the images are created by using imagesc in a loop

for ii = 1:219
   %plot stuff
   title(sprintf('Angle = angle(%i), Power = power(%i), Exposure = exposure(%i)',ang(ii),pow(ii),exposure(ii)));
end

Don't call your variables angle and power since those are (useful) builtin MATLAB functions!

@Matt: If this works for you, the values have *not* been stored in a "cell". Please read "help cell".

for i = 1:219
  % Create the image
  title(sprintf('Angle = %f, Power = %f, Exposure = %f', ...
        angle{i}, power{i}, exposure{i}));
end

Are you sure that the data are stored in a CELL? If you use DOUBLE arrays instead, you need round paremthesis instead of the curly braces.
