Line Graph with 10 Minute Intervals on x-axis

Hello Power BI Users

Please I started working on a personal IT project that uses Power BI to create dashboards.

I want to create a line graph with 10 minutes intervals that shows a plot of KPI like ASR (Answer Seizure Ratio). The attached image below is a similar example.

    Create another calculated column

    Setup Time2 =
DATE ( YEAR ( 'BI Folder'[Setup Time] ), MONTH ( 'BI Folder'[Setup Time] ), DAY ( 'BI Folder'[Setup Time] ) )
    + TIME ( HOUR ( 'BI Folder'[Setup Time] ), FLOOR ( MINUTE ( 'BI Folder'[Setup Time] ), 10 ), 0 )

     

    And an extra measure

    ASR in last 10 mins = CALCULATE(DIVIDE (SUM ('BI Folder'[Answer Status]), COUNTA('BI Folder'[Session Status])),LASTNONBLANK('BI Folder'[Setup Time2],""))

    EAfang so is your question related to getting 10 min interval on x-axis from the date time column that you will have ? if yes then you will first have to calculate difference between two time columns that you will have, change their data type to duration and then using Rounding function to make it 10 mins interval.

      Thanks for taking out time to help. Let me try my best to explain what I want to achieve with Power BI more clearly. The link below is a sample file I created from the actual dataset to quickly recreate the problem.

       

      https://drive.google.com/file/d/0Bz0yHmC0QyGYYVNhZ1RickN0MVU/view?usp=drivesdk

       

      There are three columns. 'Setup Time', 'Session Status' & 'Session Duration'
      A 'Session Status' of 3 means that the call was answered.
      A 'Session Status' of 2 means that the callee's phone rang but no pickup.
      A 'Session Status' of 1 means that the call didn't get to the callee's phone or it was switched off.

      The KPI I'm interested in at the moment is ASR.
      ASR means Answer Seizure Ratio in percentage. So this is how I intend dealing with it;

      1. I know that every ROW of data represents one session / call, so a row count should give me number of calls.
      2. So I created a calculated column called 'Answer Status'
      Answer Status = IF('BI Folder'[Session Status] = 3, 1, 0)
      3. I then created a measure called ASR as follows
      ASR = DIVIDE (SUM ('BI Folder'[Session Status]), COUNTA(BI Folder'[Session Status]))

      I want to get the ASR at every 10 minutes interval (and it doesn't have to be on a line graph, I could use a card that updates with the latest 10 minute interval.
      Instead Power BI will give me ASR by aggregations of Year, Month or Day. I want it in 10 minutes interval instead. Please how can I achieve this?

       

      Power BI unaggregated to the minutes
