Frame a graph and verify its values with Table.
A correct expression can still look wrong when the graph window is poorly framed. Use Window, Fit, Zoom, Reset, and Table to separate display problems from mathematical ones.

What should you do when a Callie Pro graph looks blank or too small?
Fit adjusts the visible bounds around supported plotted content, while Window gives direct control over graph limits and Zoom changes the current scale. Reset returns the view to its standard state.
Table lists sampled values for visible expressions, which helps confirm whether the expression is producing sensible output even when the graph framing needs work.
Diagnose the view before changing the math.
- 1
Confirm the expression is active
Make sure the intended expression is valid, visible, and selected before changing the graph window.
- 2
Try Fit
Use Fit when the curve exists but appears too small, too large, or outside the current view.
- 3
Set or adjust the Window
Enter useful horizontal and vertical bounds when the problem requires a deliberate domain or range.
- 4
Verify in Table
Open Table to compare sampled x-values and function values without depending on the visual scale alone.
Try a concrete case.
A parabola outside the current view
Use Fit, then inspect Table values around the vertex before choosing a tighter Window.
Y1 = (x - 20)^2A trigonometric comparison
Use a suitable trigonometric window, then compare sine and cosine values at the same sample positions.
