interpolation distribution curve

[Dermot1000]

Hello,
I have a statistical histogram that I want to turn into a curve.
I have a 2D Array with 10 Points from the histogram that I added a first and a last point so that the curve starts and ends in zero. I tried the spline and the polynomial interpolation but always get funny curves, that do not fit my purpos. What kind of interpolation recognizes maximas and minimas? Because if the points of my histogram have to be maximas or minimas if they do not lie between other points.
Greetings Dermot

Could you provide a bit more detail. You say you have a 2D array. What is in the second dimension?

What is the purpose of the interpolation? Do you have any additional knowledge about the histogram data? For example if it is expected to be a Gaussian distribution, you could fit it to a Gaussian curve.

It is not clear what you mean by the maximas/minimas statements. Could you provide an example?

Sorry - that sure was to little information.
I added a VI that shows what I try to do.
I have about ten measured values of the same process and want to display the frequency distribution. Because I only have a few measured points. I won't always get a gaussian curve. I don't like the histogram view so I want to fit a curve in the histogram.
Best regards Dermot
