Trying to plot a variety of functions and nothing shows up in the plots.
I have 23 yrs of MathCad experience, but cannot figure out what Smath is looking for to plot three very simple function (See attached file).
Additionally, I am not sure why an equation needs vectorized to output the answers in the normal distribution equation.

Equation 1 - Normal distribution does not solve as a function until it is vectorized. Why?
Equation 2 - f(x):x^3+2*x*sin(0.25) solves without vectorization but will not plot. Why?
Equation 3 - f(x):vectorize(1/{σ*sqrt(2*π)}*e^{-1/2*({x-μ}/σ)^2}) solves with vectorization but does not plot (2D or X-Y plot method). Why?

Equation 2 also needs vectorized to get the correct results.
You don't have to do this in MathCad, why here?

You have defined a vector of values ​​for x. If you use the X-YPLOT plugin you need to change the variable. If instead you use SM native 2D graph then it already works as you expect

First Solution Found
This allowed me to plot Normal Distribution Function.
augment(x,f(x))

Solved for now. On with the learning experience.
Thanks....

Hi, if you need a quick plot I recommend you use 2D standard plot you can plot functions f(x) directly , if you need a more configurable plot use XY plot but you need to put your data in a special format. File not found.File not found.

You don't need to use range() and augment() if you want to plot sections.
You can limit it with if-else() or cases().

1. Show the two other ones on same document for doctoring.
2. Your sigma makes no sense !
3. BTW, in Samples you should find my Stat Treasury [10 WS]
Hard to find such immense Compendium.
4. If you can't download, please let me know

... besides the pure statistical application,
you can use to fit data sets [Fréchet US Rainfall ...]

There is about 24 built-in PDF in Smath ... f(x) menu
as well as CDF, ICDF

1. Discretize the range you want and plot ... No vectorize.
2. Plot scalar directly.

... in most applications inc(Low,High,step,f(#)) is preferred

Scalar plots have limited use, mostly confirm the project.
Discrete plot can be used for subsequent application/export.
1. Collapsed the algo at top utilities.
2. Use it infinitely in-situ use [range each f(x) at will].

Try this file.
