# Plot not displaying given axis limits

When trying to plot a graph I have set the limit using the following code:
ylimit = 1.5;
ylim([-ylimit,ylimit])
axis equal
But the plot produced does not have that axis limit:
Does anyone know why this is happening and how to stop it?

Comment axis equal and plot it
%if true
% code
% end
ylimit = 1.5;
ylim([-ylimit,ylimit])
%axis equal

Or use xlim just like ylim. Ylim seems to work fine.
% if true
% code
%end
xlimit = 3;
xlim([-xlimit,xlimit])
%axis equal

We don't see enough of your code to see what's causing that. It could be caused by any of these possibilities or another reason
• The cirlce isn't complete and the axes are fine.
• you're Setting xlim somewhere
If you're setting axis equal prior to ylim, it would also cause this problem. For example,
th = linspace(0,2*pi,100);
x = sin(th);
y = cos(th);
plot(x,y,'r-')
hold on
plot(-3.5, 0, 'g*')
axis equal
ylim([-1.5, 1.5])
grid on

Hi,
From my understanding you are trying to limit your plot axis."axis equal" command uses the same length for the data units along each axis but not exactly plot in that range.
