I am plotting the graph using stem. What code should I write to label the x-axis with spectrum? I have tried xticklabels but it is not working.

Do you want to include those x values to have ticks as well?
If that is not something you want to do, please specify exactly what you want to achieve.

The spacing is too close for extra tick labels to work well, probably. If the idea is to identify the values at the locations of the plotted values, an annotation/text at the locations of interest is probably the way to go. See <a recent thread> for the idea; salt to suit...

Hi Teoh Chee Jin,
As per my understanding, you are trying to have a xtick for each observation on the plot. We can change the input value to 'xticks' function to solve the problem. Let 'observations' be the array of x-axis co-ordinates then.
ticks = -2 : 2
ticks = sort([ticks observations])
xticks(ticks)
If you want to just label the locations of the plot values then read this thread.
For more information on ‘xticks’ function refer the following MATLAB documentation.
Hope this helps,
Thank You!
