Adding variable values into legend

1.060 views (last 30 days)
Hello, i am looping over different valuesthat effect the plot and i can get a legend that shows how these values relate to the lines shown in the plot. However i would also like to add another legend or something similar that will show some parameters that are manually set in the program.
ie: If gravity would effect the shape of my plot and i set gravity to 10 i would like to be able to have it show on the firgure that "10" was the value of gravity used for run of the plot

There are several ways to do that.
One is:
plot((1:100), rand(1, 100).*sin(1:100))
gravity = 10;
gravstr = sprintf('Gravitational Acceleration is %.1f today',gravity);
Experiment to get the result you want.

As always, my pleasure.
I don’t entirely understand what you’re doing.
The legend call wants one plotted object (line, marker, etc.) for each item in it, and will complain if there are more legend items than plotted objects. In that context, the text call is likely your best option. I’ve used an ‘empty’ subplot position for a legend location from time to time, using the 'Position' property to place it.

Maybe this code can help you:
x = 1:.1:3;
colors = jet(5);
for n = 1:5
hold on;
