Rescaling axes using transform filter

Hello, my data is plotted on x-axis range 0-0.5. I used transform filter to rescale my x-axis with a factor of 0.0006 and hence the x-axis range becomes 0-0.0003. But when I plot my data on the transformed x-axis I get range of 0.00024 only and the last part of my data is not plotted. Please explain how to fix this. Picture is attached.
