Question

I am plotting two curves in different axes in the same figure with plotyy. The first curve ranges from 10^-4 to 10^-1 and the second curve ranges from 0 to 10. If I plot in the following way,

[AX, H1, H2] = plotyy(x, y1, x, y2, ‘semilogy’, ‘semilogy’);

They will both plotted as semilogy and with correct scale in y. But I don’t want to show y2 in log10 scale, so I change

[AX, H1, H2] = plotyy(x, y1, x, y2, ‘semilogy’, ‘plot’);

However, then on left and right y axis, the tick only show the min and max range, all detail inbetween gone. Why’s that?

Answer 1

Try this:

%# create some data resembling what you described
x = 1:100;
y1 = rand(size(x))*1e-1 + 1e-4;
y2 = rand(size(x))*10;

%# plot
hAx = plotyy(x,y1, x,y2, 'semilogy', 'semilogy');
set(hAx(2), 'YScale','linear')
