I'm trying to use radmap to show a number of objects that move (between updates, approximately every 500ms). I'm showing the track the object has taken as a number of line segments (currently using PolyLineView). I've bound the layer item source to a collection containing the object (as an image) and a line segment showing for each track update. Can you advise on the best way to cause the tracks to be redrawn when a track update happens? I've been using an observable collection but the layer does not seem to update in response to the addition of a new line segment view model.
The other problem I have is that I'd like to draw each line segment as a colored line with a shadow effect - I'm not sure if this is possible?
I'd also like each line segment to show a tooltip when the user hovers over the line segment - is there some way I can increase the size of the area the mouse has to be over to show the tooltip (i.e. if the line thickness is small the user have to position the mouse very accurately.
Thanks for any suggestions received,
