Home: Menu Reference: Graph Menu: Plot Points/Plot As (x, y)/Plot As (r, theta)
This command plots one or more points on the marked coordinate system at the specified coordinate location. If there is no marked coordinate system, Sketchpad creates a default coordinate system.
If you have two selected measurements or calculations and there’s a marked polar coordinate system, the command appears as Plot As (x, y) or Plot As (r, theta). When you choose the command, Sketchpad creates a new plotted point at the coordinates determined by the two selected measurements, with the first measurement used as the x or r coordinate and the second as the y or θ coordinate. As the measurements change, the position of the plotted point changes to match.
If you don’t have two selected measurements or calculations, the command is Plot Points. This command brings up a dialog box that allows you to plot one or more points on the marked coordinate system by entering the coordinates of each point to plot.
In the dialog box:
· Choose Rectangular to plot points using (x, y) values or choose Polar to plot them using (r, θ ) values.
· Click Plot to plot the current values; the dialog box remains open to allow you to plot additional points.
· After plotting your last point, click Done to close the dialog box.
You can type numbers with decimal points, or you can type expressions such as 2+3 and p/4.
