Change x-axis.

I wanna start x-axis from 1500.Is there function for that. using axis([1500 1600 0 inf]) doesnt work

Use xlim and ylim

It shows blank fig....actually i wanna show x-axis in term of wavelength starting from 1500

[Azzi Abdelmalek]

xlim([1500 inf])

[sashish acharya]

Its out of range

[Azzi Abdelmalek]

You asked how to set x-axis from 1500, that's what the picture shows, what is you problem?

[sashish acharya]

But sir its not showing the graph...I want graph in that range starting form 1500 instead of zero.

[Azzi Abdelmalek]

xt=get(gca,'xtick')
xt1=linspace(1500,1600,numel(xt))
xtck1=arrayfun(@num2tr,xt1)
set(gca,'xticklabel',xtck1)

You have no data at x=1500, so why would you want to start it there? If you mean that you want to relabel the x-axis, you can use

xticklabels = get(gca,'xtick');
xticklabels = xticklabels + 1500;
set(gca,'xticklabel',xticklabels)

Oh, it looks like you want to convert frequency to wavelength. That has been asked many times, e.g. http://www.mathworks.com/matlabcentral/answers/80537-how-do-i-convert-the-x-axis-of-an-fft-from-frequency-to-wavelength
