Here sections for my x and y data:
X:
0, 0.048522, 0.097044, 0.145566, 0.194088, 0.24261
and Y:
-0.626144, -3.172536, -2.938785, -3.454333, -3.813695, -1.108578
I want to know the y value for specific x values, such as 0.04, 0.08, etc.
Edit: I have attached the whole data here if you want to take a look.

What you want is impossible without fitting a function to your data. This can be achieved in many ways, for example by fitting a quadratic curve to your data with polyfit.

My point still stands. You need to fit a function (or use a spline method) before you can interpolate data. That you have 400 points instead of 6 doesn't really matter (although it may improve the fit).
