Piece wise functions with 3 pieces

[steve]

I'm able to correctly graph a piece wise function with 3 pieces correctly by using the when function. When I graph my problem however, my 3 graphs are connected. I can tell where the end points of each graph are at, but is there a way to do it so that all 3 are not connected? I'm using the dot method for the graph.


Thanks

Hi steve,

Based on the information you have given me, I am unable to really make any conclusions at all. You definitely need to post the function you are graphing--you may know what it is, but we can't read your mind.

However, based on previous experience, you might try:

1) Check and see if discontinuity detection is on, which can be found in the Format menu ( [Diamond]+[|] ) of the graph screen.
2) If there are gaps between the functions (as in gaps in x-values), in the else portion of the final nested "when(" statement, use "undef" so it is not drawn.
3) When you are all done, you should only have one graph, no matter how many pieces you need, by multiple nesting the "when(" function.

Hope this helps!

Wonderful, steve!

If it wouldn't be too much trouble, could you post your problem, and how you fixed it? I know you already have your answer, but perhaps an explanation of your situation can be helpful to other users with similar issues.
