Native Histogram VI seems to have error

[Goju-Ryu]

Dear all,

I've been working on something where I need histograms but it seems to me that there is something wrong with the LabVIEW native VIs.

As an attachment, I send you an example I made to support what I'm saying.

I want the histogram to have 1000 bins with the minimum boundary equal to 0 and the maximum boundary equal to 1. The histogram is built from 500 random values.

The problem is that I cannot make the histogram to have the bins limited between 0 and 1, including 0 and 1.

Maybe I'm just interpreting something wrong but it would be interesting to have your feedback.

Thank you very much in advance!

Best regards!

You should read the "detailed help" for the histogram function. The X values are the centers of the bins. For 1000 equally-spaced bins over the range of 0 to 1, the first bin goes from 0 to 0.001 (center 0.0005) and the last from 0.999 to 1 (center 0.9995). The histogram function is doing exactly what it is documented to do.

If you want your bins numbered from 0 to 1 inclusive, you need 1001 of them, over a range of -0.0005 to 1.0005.
