Draws a line between a set of two coordinates.
Line xStart, yStart, xEnd, yEnd, drawmode
Menu Location
This command can't be found in any menu besides the command catalog.
This command works on all calculators.
X byte(s)
The line command draws a line between two points. By default, the drawing mode is set to 1, which draws the line normally, so it doesn't have to be included if drawing a regular line.
Line 0, 3, 0, 9
Advanced Uses
The drawmode can be set to 0 to draw a "white" line, which will remove the pixels on the path of the line.
Line 0, 3, 0, 9, 0 //removes the line
You can also invert pixels on the line using -1 as the number argument.
Line 0, 3, 0, 9, -1
