Showcase Screenshots

The Main UI Contains

New Child Window
Exit Current Window
Enter and Clear the Equation (Enter the equation is triggerd by pressing Enter)
Enter Limits (from, to, and step)
Graph and Clear Buttons (Disabled Until write Equation)

After Drawing a Simple Graph it Shows with a Random Color and Legend With the Function Definition

Can Insert Multiple Graphs at the Same Screen

Invalid Equations Popup Window

Invalid Range Because of From being greater than to
