The next thing you may want to do is choose the graphing options that you want. You can choose the size and the shape of the data points, the density of the graph, and the scale of the X and the Y axes. It is useful to note that by placing the X and the Y axes in the right place and scaling the axes to the proper size you can "zoom" in on any part of the coordinate plane.
GRAPHING
At this point you have written a function, edited it into a standard form, set all the graph options for your graph, and moved the axes to the best position for your function.
You are now ready to plot your function.

There is one feature of the plotting mechanism that experienced users of HyperCard may want to know about. This stack uses the painting tools to plot the data points of your functions. In effect it's taking a paint brush and dabbing it on the the right spots. With the options card you can set the size of the paint brush.
I assumed that most people wanted the data points in black, but if you prefer you can set the pattern to something else besides "black". If the pattern is not black you will be warned before plotting your function.
You can create great effects with this. Try plotting a function with a large black circle, and then plotting the same function with a smaller grey circle. Pretty neat.
