Power BI Visual data points limitation

Hi pankajnamekar25 

It shouldn’t normally be an issue with only ~20 points on the X-axis. The limitation is likely caused by the number of categories in the legend or by the combination of multiple categories and years, which can result in a high total number of data points.
To understand the problem better, it would help to see your actual data structure and intended output.
Please share a link to a cleaned PBIX file (with any sensitive data removed) hosted on a public service, so we can review the setup and suggest a proper workaround.

Hi pankajnamekar25 

Visuals won’t render more than 3,500 data points (for stacked column charts), so when you have many years × many categories, some values get dropped.
To work around it, you can:

• Reduce the number of categories or years shown at once  e.g., filter to a shorter date range or top N categories.
• Pre-aggregate data in Power Query/DAX so the visual plots fewer total points (e.g., combine smaller categories into “Other”).
• Switch to a different visual type like Table or Matrix (they can handle more points) or a Line chart with fewer series.
• Use slicers or drill-through so users can explore subsets instead of loading all data in one chart.

There’s no setting to “turn off” the limit  the fix is to reduce data density or choose a visual that can handle more points.
