Forced to summarise

[Prinsh]

Hello everyone,

I was working on some data viz for ASX ETFs by sectors for comparision. Got some clean data off yfinance and built a dataset as such:

On excel I am able to generate a time vs close price line chart for a sector. I was trying this out on PowerBI with all the sectors, so date on X, Sector on Legend and close price as Y, however I keep getting forced to summarise the field, even though on the table view I have it set to decimal and don't summarise. Could this be an issue with my dataset? or maybe I am not using the plot for its intended use? Any insights are welcome!

Hi @Prinsh 

Whatever field placed in Y-axis has to be summarized one way or another. After all, that is meant to show the summarized data by legend or X-axis columns. Not summarizing works on tables and matrices (column/row headers) where each distinct numeric value can be in its own row.

Hi,

Even if you click on the SUM function, it should not matter because there will always be onely 1 instance of a date and sector record.

Hi @Prinsh ,

The issue you're facing is likely due to the structure of your dataset. Since your dates are in columns (wide format), Power BI struggles to treat them as a proper time series. To build a time vs value plot with sectors on the legend, you’ll need to unpivot your data first.

Here’s what you can do:

1. In Power Query, select all the date columns (e.g. 4/01/2023, 5/01/2023, etc.)
2. Right-click and choose Unpivot Columns
3. This will give you a new structure like:

   ASX Code | Sector | Date       | Value
   A200     | Financials | 4/01/2023 | 102.5
   AAA      | Real Estate | 4/01/2023 | 98.3
   ...

1. Now in your visual:
   • Put Date on the X-axis
   • Value on the Y-axis
   • Sector in the Legend

This will allow Power BI to treat the dates as a continuous axis and plot each sector’s trend over time.

Let me know if you need help with the unpivot step or setting up the visual.

Use MIN., MAX or AVERAGE to summarize

You know that a sector does not have more than one ticker price for a date,

but Power BI does not know that.

It need MIN., MAX or AVERAGE to compute a scalar value to plot a line graph.
