I have encountered a couple of problems while working on this and would greatly appreciate if somebody could help/point me to the right direction.
I have about 5000 points that I am returning from a database, parsing them, and displaying on my map (a state in the USA). When my app finishes rendering, the entire state is full of points and you cant make anything out of it. Now, so my understanding, simplemakersymbols, when declared have pixel size, so you cant increase the size dynamically when zooming in. Is there any alternative to this?
I tried first declaring a smaller size, and then once zoomed in to a certain scale, I redeclare all the points with a larger pixel size value. Hence all this rendering and rerendering takes a while before all the points are displayed again. So is there a better way to accomplish this task?
Edit 1.0: I am using arcgis 10.1 and create points based on data i receive from database on fly.
