Hi, I'm trying to use the user input from input as a legend for graph in a plot function. I would like my function to use the string input from the user as legend.
for jj = 1:dim
legend2 = ['Enter a legend for curve ' num2str(jj) ': '];
LegendCell(jj) = input(legend2);
end
[...]
l = legend(LegendCell,'Location','southwest');
For now, no legend is added to the plot, and I already tried differents conversion from string to string cell, array etc...
When I do this outside of the function, it works fine, so my guess is that the problem is from the data coming from the "input"
Legend(1) = "Sine";
Legend(2) = "Cosine";
x = 0:0.1:10;
y = sin(x);
y2 = cos(x);
figure()
plot(x,y)
hold on
plot(x,y2)
legend(Legend)

Change the input call to:
LegendCell{jj} = input(legend2,'s')
That worked (for one legend entry) when I tested it.
