Horizontal bar charts

[talderton]

Hi everyone,

I have created the table shown below that shows the % of positive answers by students for each school.

I have used the following calculation in my table:

Positive response percentage of students = DIVIDE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLSELECTED(('MACSIS 2019 and 2021 survey restructured'[Positive_response]))))

(The variable 'positive response' is a simple binomal variable with the categories 'positive' and 'negative''

I now want to do the following:

Create a horizontal bar chart from the tabular data showing schools down the side rank ordered by the % positive. I also want to remove the 'positive response' column. Please see what I mean from the viz created in Tableau.

Any ideas how I do this in Power BI?

Thank you!

Thanks.

It didnt like this formula.

So I changed it slightly to get the correct variable names.

Now it still doenst like one aspect of it (shown in red below):

DIVIDE (CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),('MACSIS 2019 and 2021 survey restructured'[Positive response]=("Positive"), CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),('MACSIS 2019 and 2021 survey restructured'[Positive reponse]] in {"Positive","Negative"}))))))

Can you advise?

Thanks

Hi @talderton 

Whether you mean to show the ratio of negative types and positive types, if you need to calculate this, you can consider the following two methods

1.Put the [Positive response] into a slicer, then create the measure

Positive response percentage of students = DIVIDE (CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),'MACSIS 2019 and 2021 survey restructured'[Positive reponse]] in {"Positive","Negative"}))

2.You need to create two measures, one is positive, the other is negative. the measure can refer to the original measure I offered before. The originsl measure calculates positive type, then you need to create a new measure to calculate negative type.

Hi @talderton 

Please try the following code again

Positive response percentage of students = DIVIDE (CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students])),CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),'MACSIS 2019 and 2021 survey restructured'[Positive reponse]] in {"Positive","Negative"}))

Hi @talderton 

I made some change on it please try the following code

Positive response percentage of students = DIVIDE (CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students])),CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),'MACSIS 2019 and 2021 survey restructured'[Positive reponse] in {"Positive","Negative"}))

THanks very much. That now works to create the variable.

But how do I now use that to create the visualisation in my first post? i.e. with schools on the Y axis, the survey year on the X axis showing this calculated as the measure with the change between the two latest years shown in the final column?. Like this:

Hi @talderton 

You can use the following visual

But it cannot display the change , the default visuals power bi have offered cannot do this

Hi @talderton 

You can refer to the following measure

Positive response percentage of students = DIVIDE (CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),[Positive_response]="Positive"),CALCULATE (sum('MACSIS 2019 and 2021 survey restructured'[Number of students]),ALLEXCEPT('MACSIS 2019 and 2021 survey restructured','MACSIS 2019 and 2021 survey restructured'[Enumber]),[Positive_response] in {"Positive","Negative"}))

 

Then put the measure to the visual and set sort by Measure

Best Regards!
