Challenge Creating Cumulative Chart in Power BI with Distinct Token Count

[marquesjef]

In a table named 'token_ativos' with a column named 'created_at' for dates and a 'token_id' column containing the IDs of active tokens, where the 'created_at' column represents the creation date of the active tokens. In Power BI, I need to create a chart that provides the sum of active tokens for each month. For example, if there were 2 active tokens in February and 2 more were created in March, the chart should display 2 for February and 4 for March. Please create a DAX expression that gives me this cumulative total when placed on the X-axis with 'created_at'.

When I place the distinct count of 'token_id' on the Y-axis and 'created_at' on the X-axis, the chart only returns the count of tokens created each month. I need the cumulative count instead.

Hi @marquesjef ,

Hope everything is going well.

Please follow these steps:

1. This is the original data I created.

2. Create a measuring value, the DAX syntax is as follows:

Cumulative Total = 
CALCULATE(
    COUNTROWS('token_ativos'),
    FILTER(
        ALLSELECTED('token_ativos'),
        'token_ativos'[created_at] <= MAX('token_ativos'[created_at])
    )
)

3. Put the Created_at on the X-axis and Cumulative Total on the Y-axis.

At this point, you have realized your needs. If you have other questions, please contact me at any time.

The pbix file has been attached.

HI,

I recommend checking out this article by SQLBI: Computing running totals in DAX - SQLBI
Also in February Power BI udate visual calculations are now available in preview. Here is an example video about these: Power BI Feb 2024 Update: Visual Calculations Walkthrough! - YouTube

As for your dax:
var _mdate = max('Calendar'[date)
return
CALCULATE(COUNT('token_ativos'[ 'token_id']), ALL('Calendar'),'Calendar'[date]<= _mdate) 

This assumes ou have calendar table and relation between it and your fact table.

Here is an alternative with YTD.

CALCULATE(COUNT('token_ativos'[ 'token_id']),DATESYTD('Calendar'[date])).

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!
