WAD - 2 geocharacteristics in the drilldown

Hey experts,

I am working on geovisualization. What I try to do is, to show dynamic geo-characteristics, as points or so with the help of the coordinates of longitude and latiude. After some struggeling, this works fine, and I receive a map with triangles at the corresponding places.

Any idea where to change the format of these triangles (shape --> converting it into a circle, or the color)?

Going further: What I want to implement next is this map with the point layer with an underlying map with the borderlines of a country, states, postalcode areas etc. The background is, that it is indeed a lot of work to display dynamic geographic information (or static with geo-characteristics), but it`s in the end not worth that much.

My vision is to show e. g. customers per state, which means all the customers of one state are drawn as points within this state on the map. This could, in my opinion, be a great and efficient way to analyze customer`s density.

Now: The problem of the WAD is, that only one geographical characteristic at a time can be in the drilldown. For my case I would need more than one, or I had to solve it by different layers. But that does unfortunately not work yet.

Any solutions/ tips/ experiences? Thank you sooo much!

    Marcus,

    Way to be persistent...

    1) The marker size and shape settings are in the maplayer settings. I have played with the marker size, but am not sure about shape.

    2) I have been able to implement multiple map layers in the same map item. Each layer can be tied to a different data provider. For the layer with the regions, display it first with color shading rendering. Use a KF that forces all the regions to be white.

    Hope that helps.

    Thanks

      Hey Vineet,

      thank you for your solutions.

      I will elaborte on my solutions a little more in detail, if anyone else is interessted:

      1) Choose symbol as a map renderer and you can make all the desired options like shape or alternate the color.

      2) fits perfectly! I guess you musn`t choose the same map renderer for different layers.

      Do you experts know, how to set the initial zoom level? My map is displayed with the right key figures, but I always have to use the geo-toolbar to zoom in, for it is far too little... (I`ve read about a solution, which advices to append parameters to the URL -> aren`t there any more appropriate approaches?)

      Regards

      Marcus
