J jamesnz Active Member Licensed User Longtime User May 5, 2017 #1 I've had a brief look at many of the graph/chart/plotting libraries but I dont see anythig that allows me to move an image over the view. I want to be able to touch the chart ( preferably showing some sort of slider) and this will change the data shown on the map. Here is an example of what I'm trying to emulate.(29 seconds)(except that under the users finger will be some sort of indicator that moves with the finger) "" I also hope to do this in B4i. Can anyone advise a library or tell me what components I can use that will allow me to draw lines whilst overlaying a slider that will raise events on movement.

The indicator can be implemented with a view that is moving with the finger. Example: https://www.b4x.com/android/forum/threads/indexedtable.60300/#content Upvote 0
