Hi, my code plots 3 lines onto one plot
The x-axis scale is very big, 0 to 40,000, while the y axis is very small (between +/- 0.06)
When I do my plot the x-axis shows the scale 0 to 4, (x 10^4). How do I change it so that it simply says 0 to 40,000 instead?
Thank you!

hAx=gca;
hAx.XAxis.TickLabelFormat='%d';
hAx.XAxis.Exponent=0;

hello Megan
you have to create a specific XTick / XTickLabel to represent the number the way you prefer
here an example with 5 values of the x data vector used to create the new XTick / XTickLabel
x = (0:40e3);
y = randn(size(x))*0.02;
N = 5;
xt = linspace(min(x),max(x),N);
XtLabels = num2cell(xt);
plot(x,y);
set(gca,"XTick",xt,"XTickLabel",XtLabels);
