Dashboard GeoPoint Maps now with Clustering, Bubbles, and Pies (Available now in 14.1)

DevExpress Data Blog
05 June 2014

We’ve release 14.1! It would be a travesty if I didn’t talk about a couple of additions to our GeoPoint map included in our dashboard tooling.


Before 14.1 our GeoPoint map sometimes did something like this:

Ugly GeoPoint Map

This is indeed violated our aesthetic sensibilities. In 14.1 we added a Clustering option under the data interactivity section of this great dashboard element.

Enable Clustering

The theory is that zooming out should automatically cause aggregation and zooming in should de-aggregate as space allows. As you can see, this is exactly how we implemented it:

Zooming with Clustering


GeoPoint Map Bubbles

While this seems similar to the clustered bubbles above, the size of the bubble in this instance is actually a separately bindable element.

In this case the wright of the bubble is dependent on the Production size field. Additionally you can also add a color element to the bubbles by dropping a field onto the color section. The color gradient is automatically created on your behalf (this can also be changed). Finally you can control the information on the tooltip by dropping fields into the Tooltip Data Items section.

These additional items (Weight and Color) also have their own individual legends that can be easily set using the dashboard item design options:

Almost forgot! These bubbles can also be clustered as well! In this particular case, we are simultaneously showing 6 dimensions without hurting anyone's head (and that’s not even including the clustering option).


GeoPoint Map PIe Charts

We’ve also added pie charts! In this case (above) I have also clustered them in order to give a better appearance. In essence now you can create a set of pie charts that have locational meaning. Setting this up is not too difficult.

Notice in this case we have subdivided the Production field by EnergyType. You also have the same legend options as the Bubble GeoPoint map. As you can see, the resulting visualization is not only very appealing but extremely informative to boot.

Parting Words

As we continue to innovate in this space you will see more and more features added to the dashboard component that truly gets the pertinent answers from your data.

As always, if there are any comments and/or questions, feel free to get a hold of me!
