I would like to do a graph with two y axes. I have found this. I have two questions that have no answer here:
1.how to have the two axes simply in black and not in blu and orange (very strange default choice).
2.How can I choose the limit of each axes? I usually use ylim([]), but now how can I choose the right or left axis?
Thank you

x = linspace(0,25);
y = sin(x/2);
yyaxis left ;
plot(x,y,'k');
ax(1) = gca ;
r = x.^2/2;
yyaxis right
plot(x,r);
ax(2) = gca ;
% change axis colors
ax(1).YColor = 'g' ;
ax(2).YColor = 'm' ;
ax(1).YLim % set your value here
ans = 1×2
0 350
ax(2).YLim % set your value here
ans = 1×2
0 350

Try using ylim after the plot twice.
