Map Chart performance is very slow

Shaigokul — Fri, 12 Sep 2025 09:32:39 GMT

Hi everyone,

On our side, the development has been completed at both the mashup level and in Qlik Sense. However, the entire dashboard is experiencing performance issues due to the Map chart.

The Point layer works fine, but when we add the Area layer at the state level, it significantly impacts performance.

Could anyone suggest a solution for this?

maybe this?

1.Are all layovers need at all time , all zoom levels , you can specify the zoom level for each layer?

2. Use If(GetSelectedCount(State) > 0, 1, 0) to show the Area layer only when relevant selections are made.

We tried adjusting the zoom levels, but the chart still takes time to load.
We are using two area layers:
- One to display the unselected state borders with an outline, using the condition: if(getSelectedCount(state) > 0).
- The second area layer is used to show the state areas with colors representing values.

The issue is that when both area layers are removed, the dashboard performance is very good. However, as soon as we add the area layers, the performance significantly degrades.

HI @Shaigokul

Did you upload area layers as KMLfiles or are you relying on lookups based on online available geo location. In this case obviously KML will be recommended.

cheers

We created the kml but it stored in qvd format
