A new addition to the Google Maps family. This extensions will take your data points and produce a heatmap on top of a Google Map.
A good tool easily spot areas with higher intensity of data points. There is no selection support for this extension has there is no markers available at the moment.
You can either use the extension 'as is' or use it as a base to further customize it to fit your needs.
Finally tracked down the errors when you tried to pass in faulty data.
Added a check that QV passes valid data points to Google. If you are passing an invalid data point it will log it to the console in your browser.
Also enabled weighted data points. Now the weight if your data point in the heatmap will correspond to your expression value. If you want equal weight between the points, e.g the original heatmap where the number of data points determined your heat level, set a arbitrary value of =1
If you build something awesome please share it with the community!
Im having problem with heatmap. I was trying to modify your cluster extension to work like heatmap for quite a while now, but without any success. When this extension and example got out, I was hoping that i would find out what mistakes I've made. But this extension dosen't work for me at all, even on your example. It doesn't even load the map.
Cluster extension works great. I work on QlikView 10.
I have not tried it on QV10 but most likely you have not set up your chart properties correctly. Your dimensions should be latitude and longitude and your expression can be just =1 for testing purposes.
If you upgrade to QV11 you will get the benefits of better properties dialogs in extensions.
I downloaded the QVW and the QAR file. I deployed the QAR file for Desktop and Server usage accordingly but when I try opening the QVW, I do not get the app to display the map in Web View (using Desktop). Am I missing anything?
