Graphing functions that can only evaluate whole numbers won't show any points* (Grapher app cannot render singular points on graph)

[bala7sc]

Describe the bug

Graphing functions such as "x!" that can only evaluate when x is an whole number will lead to an "empty" graph but in reality the graph isn't empty and just can't render the singular points properly as you can move to the points

Screenshots

To Reproduce

Steps to reproduce the behavior:

1. Go to the 'GRAPHER' app
2. Type 'x!'
3. Plot Graph

Expected behavior

The points should be rendered properly, Example for x! from casio classpad. (i tried with numworks board but that didn't work either)

Environment
