Plotting (Printable)

clearplot, clear-plot [Observer, Turtle]

Clears everything drawn by all plot pens, and resets all pens to (0, 0).

plot y-value [Observer, Turtle]

Plots a point at y-value, then increments the x-value of the plot pen by 1. The pen will rescale itself when it reaches plot-xmax.

plot-title [Observer, Turtle]

Returns the title of the plot.

plot-xlabel [Observer, Turtle]

Returns the value of the label of the x-axis of the graph.

plot-xmax [Observer, Turtle]

Returns the maximum x-value of the plot.

plot-xmin [Observer, Turtle]

Returns the minimum x-value of the plot.

plot-ylabel [Observer, Turtle]

Returns the value of the label of the y-axis of the graph.

plot-ymax [Observer, Turtle]

Returns the maximum y-value of the plot.

plot-ymin [Observer, Turtle]

Returns the minimum y-value of the plot.

pp integer [Observer, Turtle]

Selects a plot pen (e.g. pp 1). Subsequent plotting commands are executed by the selected plot pen. There are ten plot pens, numbered 1 through 10.

ppc [Observer, Turtle]

Returns the current plot pen color.

ppd [Observer, Turtle]

Puts the plot pen down, so that it draws connected graphs.

ppreset [Observer, Turtle]

Clears everything this plot pen has drawn and resets its position to (0, 0).

ppu [Observer, Turtle]

Lifts up the plot pen, so that it plots points individually (not connected).

ppxcor [Observer, Turtle]

Returns the x-value of the current plot pen.

ppycor [Observer, Turtle]

Returns the y-value of the current plot pen.

setplot-title name [Observer, Turtle]

Sets the title of the plot to be name.

setplot-xlabel label [Observer, Turtle]

Sets the label of the x-axis of the graph to label.

setplot-xmax value [Observer, Turtle]

Sets the maximum value of the x-axis to be value.

setplot-xmin value [Observer, Turtle]

Sets the minimum value of the x-axis to be value.

setplot-xrange value1 value2 [Observer, Turtle]

Sets the minimum value of the xy-axis to be value1, and the maximum value of the x-axis to be value2.

setplot-ylabel label [Observer, Turtle]

Sets the label of the y-axis of the graph to label.

setplot-ymax value [Observer, Turtle]

Sets the maximum value of the y-axis to be value.

setplot-ymin value [Observer, Turtle]

Sets the minimum value of the y-axis to be value.

setplot-yrange value1 value2 [Observer, Turtle]

Sets the minimum value of the y-axis to be value1, and the maximum value of the y-axis to be value2.

setppc color (or number) [Observer, Turtle]

Sets the color of the current plot pen to be color.

viewplot, view-plot [Observer, Turtle]

Opens the Plot Window.
