"Too many values" - increase limit

[hraz]

I'm using Microsoft Gantt Chart (custom visual open source). I have data with ~470 task rows after filtering (~50 distinct values), and I'm getting a "Too many values" warning, and I have missing blocks in the visual.

It is much lower than the default 1000 items for the custom view (Source). I need it to support up to 5000 items.

I tried to build the Gantt custom visual from the source, and I changed the `capabilities.json` to:

But with no luck (I was able to import my visual, but it still remove blocks).

How can I increase the data limitation for that visual?

Hi @hraz ,

As far as I know, It is possible to increase it up to 30000.

You have to add "dataReductionAlgorithm" to the capabilities.json file. Please check this offical blog, I hope it could help you solve your issue.

I added the `dataReductionAlgorithm` (as can you see in the original post) but it isn't working for me.

The Gantt Chart source code is here: microsoft/powerbi-visuals-gantt
Can you please let me know how should I edit the `capabilities.json` file to support more items?

Hi, Looked at the source code and noticed you all removed the dataReductionAlgorithm. I'm running into a similar issue on my custom visual. How did you all solve this?
