Using these tables with relationships connected, although I can not get all data to plot on line chart for each person.

Hey @TonesTables,

It looks like the issue might be related to missing data or filters in your model. Here are a few things you can try to troubleshoot the problem:

  1. Check for missing UUIDs or names
    You mentioned that not all rows have a UUID or person's name. If your visual relies on a relationship to a person table (or if you’re using a slicer), those rows might be excluded. Try removing any filters or slicers on people to see if more data appears.

  2. Test your data with a table visual
    Before using the line chart, I recommend creating a simple table visual with the following fields:

    • UUID

    • Event

    • EventType

    • EventDate

    • EventScore

    This helps verify if the expected events are actually present and have valid data (especially EventDate and EventScore).

  3. Avoid overlapping data points
    Since your Y-axis only uses values 1, 2, and 3 (for EventScore), multiple events might overlap on the chart. This can make it seem like some data is missing.

  4. Try a scatter chart instead
    If the line chart still isn’t displaying everything, try switching to a scatter chart with:

    • X-axis: EventDate

    • Y-axis: EventScore

    • Legend or Details: EventType or UUID

This often gives you a clearer picture when dealing with discrete values like 1, 2, and 3.

Hope this helps! Let me know if you want help checking your data model or relationships.

Hi @TonesTables ,

 

Lookslike your Data model is mssing relationships.

can you share a snapshot of it?

 

Thanks and Regards,

Hi @TonesTables 

If your goal is to create a chart where:

Y-Axis: EventScore (1, 2, or 3)

Legend: EventType (Lifestyle = 1, Education = 2, Sport = 3)

Data Label / Title: Event Name (e.g., “Xmas Break”, “Study Period”, “Test Match”)


then the issue is that Power BI does not automatically display a text event name as a data label unless it is used on the axis or provided through a measure.

Here are the correct configurations to make it work:


---

✔ Option 1 — Column/Bar Chart (Recommended)

Use the event name as the X-Axis to allow Power BI to show it as a label.

Fields:

X Axis: EventName

Y Axis: EventScore

Legend: EventTypeName (Lifestyle, Education, Sport)


Then enable labels:

1. Go to Format


2. Expand Data Labels


3. Turn Data labels = On


4. Turn Category labels = On (this ensures the event name appears)

 

This configuration displays:

EventScore on Y

EventType as Legend

Event names as visible labels

 

---

✔ Option 2 — If you need the Event Name as a label on a Line/Scatter chart

Create a DAX measure to use as the label:

Event Label = SELECTEDVALUE(Event[EventName])

Then:

1. Go to Format → Data Labels


2. Set Label Style = Category


3. Ensure Data Label = On

 

This forces Power BI to show the event name on each point.
