TkPlotter is a lightweight 2D function plotter built with Tkinter. It allows users to visualize mathematical functions interactively, supporting zoom, pan, and customizable plot ranges.

• Function plotting: Enter any mathematical expression in terms of x (e.g., sin(x), x**2, etc.)
• Interactive controls: Zoom and pan using mouse and hotkeys
• Customizable ranges: Set x_min, x_max, and step size
• Grid and axes: Auto-generated grid and axis labels
• Collapsible hotkeys panel: View and hide available hotkeys
• Robust evaluation: Safe math expression evaluation

Run the application:

python main.py

• Function input: Enter the function to plot
• Range controls: Set x_min, x_max, and step
• Plot/clear/reset buttons: Control the plot display
• Canvas: Interactive plot area
• Hotkeys panel: Shows available shortcuts

• Mouse wheel: Zoom X (Ctrl for faster)
• Shift + wheel: Zoom Y (Ctrl for faster)
• Left mouse: Box zoom
• Esc: Cancel box/reset
• Right/Middle mouse: Pan
• Enter: Plot
• R: Full reset
