Power BI Visual Not Showing All Categories

Hi Nabha-Ahmed 

There are several reasons why a visual in Power BI won’t show all the categories from your column — and it’s not necessarily related to the number of rows in the table. A few key points to check:

1. Visuals do not display row-level data
A bar chart shows aggregated values.
If your categories repeat across rows, Power BI will group them and show only the unique categories that actually have a value under the current filter context.
So even if the source table contains many rows, the visual may show fewer categories.

2. Filters and context
Check for:

Visual-level filters

Page-level or report-level filters

Hidden filters from slicers

Interactions with other visuals
Any of these can remove categories even if the source table includes them.

3. Categories with no data
If a category has a blank or zero measure result, many visuals will hide it by default.
This is common when the measure returns BLANK() after filtering.

To give more accurate guidance, it would really help if you can share:

A small PBIX with a mock dataset that reproduces the issue

A screenshot of the expected outcome

That will allow checking the model structure, relationships, and measure logic.

Thanks everyone for the insights.
I tried a few checks on my side and found what was causing the issue:

I noticed that some categories were not appearing because the measure was returning BLANK() for them under the current filter context.
Once I adjusted the logic to return 0 instead of BLANK(), all categories started showing correctly in the visual.

I also verified that:

There were no hidden visual/page/report filters affecting the chart

Interactions with other visuals were correctly configured

The field used on the axis had no unwanted filtering applied

After updating the measure and refreshing, the missing categories appeared as expected.
