Putting a step in x axis

Hi,

I'm trying to put the x axis with a step of 50 nm, but the output is 0 to 350 nm instead of 0 to 3600 nm.

subplot(2,1,2);
plot(lambda./1e-9, t/1e-9);
grid on;
axis tight;
set(gca,'XTickLabel', 0:50:3600);          
xlabel('Comprimento de Onda [nm]');
ylabel('Espessura mínima [nm]');

What I'm doing wrong?

Thanks!

 %if true
set(gca,'XTicks', 0:50:3600);          
xlabel('Comprimento de Onda [nm]');
ylabel('Espessura mínima [nm]');

Use XTicks

I already try that, but it seems my MatLab version does't support it. I get the error

Error using matlab.graphics.axis.Axes/set
There is no XTicks property on the Axes class.

What is the maximum value of lambda vector ? If it's 350nm then x-axis will display up to 350nm

3600 nm

%if true
ax = gca
set(ax,'xticks', (0:50:3600).*1e-09);          
xlabel('Comprimento de Onda [nm]');
ylabel('Espessura mínima [nm]');

Try using handle

[VBBV]

There is no 'XtickLabel' or XTick but use all in small case as xtick or xticklabel.

[VBBV]

%if true
xlim([0 3600*1e-09])

Use xlim after the plot

[VBBV]

I think you are dividing lambda with 1e-9 which gives you a large number. You have ylabel and xlabel in nm. So you should multiply with 1e-9 in plot.

%if true
subplot(212)
plot(lambda.*1e-9,t*1e-9)

I solved it with xtick instead of XTickLabel.

Thanks a lot VBBV!
