Problems with legend function for plotting figure

Hi,

Below is a copy of my script for graphing a figure that has 22 inputs of data. Each input of data comes from a different variable, and I have assigned each variable a name in the legend. I would like to make a loop for the list names instead of having to input the name manually. Plus, each time I have different number of variables I'm plotting, I have to either add or remove names from the legend.

Write loops aren't a problem for me, what the problem is getting the right amount of names for the legend function. I've tried making a variable that has a list of the names, then tried to index the variable while inside the legend function, but I can't seem to get that to work either.

Any help is appreciated

Perhaps this would be a good area to use the eval().

here is an example:

bird_id = '123';pix_size = '10';stim_dir = 'N'; bdistance = '12';
legend_text = [];
for bnum = 1:3
     legend_text = [ legend_text '[''Bird' bird_id ' with ' pix_size stim_dir ' at ' bdistance '''],'];
end

 legend_text  = [legend_text '''location'',''NorthWest'''];

What the for loop does is creates the text for what goes inside the legend (location pasted at the end.

 ['Bird123 with 10N at 12'],['Bird123 with 10N at 12'],['Bird123 with 10N at 12'],'location','NorthWest'

so when i call it in

 eval(['legend(' legend_text ')'])

it should do everything inside of your long legend callout.

This works beautifully, thanks a lot!

I've never used the eval() function, thanks for showing it to me.

use it sparingly and with caution. I lost the links saying why you shouldn't default to it. But it boils down to its harder to debug.
