HP 50g normal distribution

[Cristi Neagu]

Hello,

I'm trying to plot a normal distribution on the 50g. I know the function NDIST gives the value of the curve at a given value of x, based on a mean and standard deviation. Problem is i can't figure out how to use it in a program or equation that i can then use in the plotting function.
I know that NDIST takes 3 parameters on the stack, but i can't figure out how to use it. I tried this:

Code:

<< X -> << 100 10 X NDIST >> >>

Which works as expected if i have a number on the stack, but when i go in the Y= window, i can't choose it if it's saved as a program. So i figure that the program i made must be formatted wrong, so it's not recognized as something that can be plotted. So i wrote a random equation in the Y= editor, and this is how it saved it:

Code:

<< X -> 'X+1' >>

So i tried using NDIST in that format, but i keep getting syntax errors.

So... how can i plot a normal distribution? Is using NDIST the right approach? Is there a better way?

Thank you.
