Sort by column not working

[sdavidson]

Hi,

I am trying to create a visual that shows the time a person is called out to a job out of hours.

I can get it to show with an inverted normal distribution, where the x axis runs from 00:00 to 23:59

I would prefer the axis to run from 18:00 - 06:00 to show this data in a normal distribution in the middle of the plot. (not wrapping around each end of the visual )

I thought i could do this by creating an index table (below), creating a relationship between the times and sorting the time by the index. But when i click on the time column and say 'sort by index', nothing changes. 

If possible i would also like to group the data into 30 min slots to make it look a bit less busy but havent worked that bit out yet.

Any ideas why my data isnt sorting? any help would be really appreciated!

Hi @sdavidson ,

According to your statement, I think you are using "Continuous" in X-aixs Type. I think you can select “Categorical” in X-axis Type. 

However this will expand your X-axis in your visual and show all time. Result is as below.

You can add a new Timegroup column and New Index for this group in Power Query Editor.

New Time Table:

let
    Source = List.Times(#time(18, 0, 0), 1440, #duration(0, 0, 1, 0)),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "Time"}}),
    #"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"Time", type time}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index for Time", 1, 1, Int64.Type),
    #"Inserted Hour" = Table.AddColumn(#"Added Index", "TimeGroup", each #time( Time.Hour([Time]),0,0)),
    #"Grouped Rows" = Table.Group(#"Inserted Hour", {"TimeGroup"}, {{"Rows", each _, type table [Time=nullable time, Index for Time=number, TimeGroup=time]}}),
    #"Added Index1" = Table.AddIndexColumn(#"Grouped Rows", "Index for TimeGroup", 1, 1, Int64.Type),
    #"Expanded Rows" = Table.ExpandTableColumn(#"Added Index1", "Rows", {"Time", "Index for Time"}, {"Rows.Time", "Rows.Index for Time"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Expanded Rows",{"TimeGroup", "Index for TimeGroup", "Rows.Time", "Rows.Index for Time"}),
    #"Renamed Columns1" = Table.RenameColumns(#"Reordered Columns",{{"Rows.Time", "Time"}, {"Rows.Index for Time", "Index for Time"}}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns1",{{"Index for Time", Int64.Type}, {"TimeGroup", type time}})
in
    #"Changed Type1"

Sort TimeGroup by Index for TimeGroup and create a the visual. Result is as below.

Thanks! Switching to categorical has sorted the x axis issue. 

Sorry im pretty new to BI, where do i enter the code for the time group table?

That should work if your column is a true time column and does not have a seconds component.
