How to fix cursor at one particular value X?

[Ben121]

Thank you for pointing it out. I removed the case structure. Now I am able to move the cursors and select the desired section in continuous mode. 

One more problem I am having in this VI. Why the fitted curve using polynomial fitting is giving wrong Y axis values?

"Wrong" is a useless word unless you tell us in what way it is wrong (not a good fit, missing, wrong size, wrong alignment, etc.)

I cannot test, because I don't have your data. To get the subset between datapoints of an array, use a locked to plot cursor, and the cursor index property  as follows. Note that the min&max function ensures that the cursor order does not matter.
