How to get plot to show exactly the x-axis range desired?

Hello

My question might be a bit odd but I have used plot in matlab and obtained some figures. The ones that I have obtained look something like this:

Which as it can be seen, it covers competely the x-axis and shows the x-axis only for the desired values.

Now I am plotting the same function but varying another variable which is

 tau1=0.01:0.01:0.10
 

when plotting the figure I get:

How can I get rid of the extra space in the x-axis where my function has no values?

Thanks!
