public class Continuity
extends SimpleGraph

This applet extends the SimpleGraph configurable applet. It adds up to 6 DrawGeometrics, useful for showing discontinuities. You specify the location of the points in the examples by following the limits with another semicolon, followed by one of "open" or "closed", a comma, and then a pair of comma-separated numbers. You can add more than one by including another semicolon and repeating. The pair of numbers represents the x,y coordinates of the point. For example, here is the param value string for an example of a function with a jump discontinuity:

A Jump Discontinuity;(x<1?1:2);;open,1,1;closed,1,2

The first part is the title, the second is the function definition, the third (two semicolons in a row) is for the limits (which are missing in this example), the fourth part (i.e., open,1,1) is the coordinates of the open point, and the last part (i.e., closed,1,2) are the coordinates of the closed point.
You can also specify dashed-lines for use as asymptotes by setting the first element to "asymptote", followed by a comma and then four comma separated numbers, representing the x,y coordinates of two points on the line. For example, to show a vertical asymptote:

A vertical asymptote;1/(x-1);;asymptote,1,0,1,1
which will draw a line through (1,0) and (1,1).
You can also add labeled tick marks to the x and y axes using the "XTick" and "YTick parameters, the values of which are the labels of the tick. Like points, these are only shown when an example calls for them using an element like "xtick,1.5" to indicate that an x tick should be shown at x = 1.5.
If you use XTick, you also have the option, via "UseTable", to add a table of values at the left side of the applet. This shows several values near the current value of xtick. If no xtick is used in an example, the table is hidden.
