5 User Editing of Charts with Mouse - ID: 499412

Last Update: Comment added ( xwedge )

Details:

I want my users to be able to drag nodes on my
linechart up and down. To do this (Java newbie), I
guess I would have to add a mouse listener to get the
mouse down event, detect which node the mouse is over,
and calculate the new value when the mouse button is
released. The only problem I think I'll have is trying
to detect which node the mouse pointer is over. Does
each dot on a line chart have a fixed width in pixels,
or even better, is there a function to give me the
data item clicked on?

thanks,
Kristian.

Date: 2002-01-04 17:57 Sender: jjsimas Logged In: YES user_id=179964 This is possible to do, and I think you are on the right track in implementing this, but I this will be pretty difficult. My understanding is that you want the user to be able to edit the dataset graphically. Out of curiosity, may I ask for what purpose? Chart2D was not designed with this in mind, and you'd have to do some real digging in the source code in order to accomplish this. For LB charts, you'd be digging in the LBGraphArea and the LBChartArea classes. My guess is that it would take me about two days to implement this feature. Without any knowledge of Chart2D's code, it might take you twice that. I don't offer very much free support, if you would like more support on this issue, then for $25 I can guide you through the code and tell you the places you need to look and so on. For $150 I can implement this feature for you. Jason
