Drawing Pixels
TI-84 Plus C Pixels
A pixel is a square dot on the TI-84 Plus C display. The Pxl- (pixel) instructions let you turn on, turn off,
or reverse a pixel (1x1 pixel) on the graph using the cursor. When you select a pixel instruction from the
DRAW POINTS menu, the TI-84 Plus C returns to the home screen or the program editor. The pixel
instructions are not interactive.
