measures do not work in line charts

Measures do not work in some charts. Line charts for example. Yet they do work in others. Scatter plots for example. Why the inconsistency?  When will this be fixed?

Re: measures do not work in line charts

Hi @friedcc,

 

What version of PBI are you using? And how are you setting up you line chart, this can happen due to context on your chart I have several charts with several measures and they all work not one that as error.

Re: measures do not work in line charts

I just downloaded the Desktop January 2018 update.  There is not much to setting up a line chart. I add a line chart to the report, then I try to drag and drop into the Axis and Values fields.   If I drag a field or calculated column from a table into Axis, it works. If I drag a measure, nothing happens. 

How can I change the "context" of a line chart?

Re: measures do not work in line charts

I have two measures:

 

Meas **bleep** Total = CALCULATE ( SUM ( WM_FIELD[REC_RES]),
    ALL ( WM_FIELD ),
    WM_FIELD[DISC_DATE2] <= EARLIER (WM_FIELD[DISC_DATE2])

 

Meas Seq No = CALCULATE ( COUNTROWS(WM_FIELD),
    FILTER ( ALLSELECTED ( WM_FIELD ), WM_FIELD[DISC_DATE2] <= MAX ( WM_FIELD[DISC_DATE2]) ))

 

They *sometimes* work in scatter plots:

They never work in line charts (or bar charts, I have not all the other visualizations):

Re: measures do not work in line charts

Hi @friedcc,

 

This is not a bug it's related with the type of charts you choose, on a line or column chart you need to select a column as your axis and a measure will no work, however since the scatter plots is a way to show correlation between two variables you are able to use the measures.

 

Depend on what you want to show and how.

Re: measures do not work in line charts

So this is not a "bug" it is a "feature."  Classic.

Re: measures do not work in line charts

What do you exactly want to achieve? Can you give some sample data?

 

Maybe it's not a question of using the measures but the way you setup your data.

Re: measures do not work in line charts

Below inserted is a small sample of data. I do not see anyway to attach a file here, so this is pretty limited. It should however be sufficient to demonstrate that Power BI cannot do what is needed. What is needed are charts like the following, which can be filtered to show the curve for different subsets of data.  Here Value would be the Quantity, and Rank would be the Meas Seq number.  That MUST be a measure, as when filters are applied, the data must be resequenced. In the past I have worked around PBI limitations by doing complex queries in SQL before importing to PBI. However in this case, with the requirement to resequence after filtering in PBI, that is not possible.  So I guess we will have to stick with Excel, as it appears to me (at least with the PBI "feature" that measures can not be used in most charts) that Power BI is incapable of producing this chart 😞

Re: measures do not work in line charts

Hi @friedcc,

 

Clearly on your chart this is a scatter chart and not a line chart because you have a relation between the two axis.

 

What is the base of the ranking? What is the value you want to sum/average/count and the value (Log) is based on what column.

 

 

Regarding the adding files just put your files on Onedrive / Google drive / Wetranfer and add the link to the post.

regards

MFelix

Re: measures do not work in line charts

Ok, here is a subset of sanitized data:

https://docs.google.com/spreadsheets/d/1AKjXhV8OGbhMF00GqLdP4y5SiFAJXGbx9H0ilVfMoU4/edit?usp=sharing

 

This was built in Excel, but Google docs appears to have converted that to Google's format. But there is a chart in that worksheet of a running total vs a sequence number. Both would be measures in Power BI, as they need to recalculate when the rows are filtered.  Unfortunately, PBI charts do not work with measures for axis values.  The PBI scatter plot visualization seems to accept them sometimes, although I find that is not consistent. 

 

What use are measures if you can't use them in visualizations? 

 

Clearly this seems to be a bug, as it is not documented anywhere that I can find, and there is no error or warning message when attempts are made to use measures in visualizations.  At this point, I can only conclude that PBI is not able to do what is needed, and we will have to leave this application in Excel. Sadly, that is more difficult to publish, and it is a reversal of our efforts to move to PBI for this kind of thing.

 

Thank you for any help you may be able to provide.
