Probably a silly question:
I want to illustrate what happens to median and mean when you change a data point. But whenever I grab a point and pull it somewhere else, it immediately jumps back to its original position .
Is it impossible to move a data point dynamically, by dragging it in the graphics window??
Hi Joachim,
Definitely not a silly question as being able to drag points is important in CODAP.
I’m confused. Your first paragraph implies that you are able to move a data point, right? If you have the mean and median displayed, you should be seeing them change while you are dragging the point. When you release the point it will slide back to its original place.
Your second paragraph implies that you are not able to drag a data point. Here are the conditions under which that would be true:
- The point’s position is defined solely be categorical values.
- The point’s values are computed from a formula.
If this remains unclear, perhaps you could share a document?
