Hello,
I'm looking for some help in how to count two columns against the same value. The data is regarding visits into and out of an area (for example, a shop, or a ward in a hospital), I have the data split into date/time columns and then the into hour and out of hour, how do I create a table that shows by hour of the day, how many people went into the area, and a second column to show those leaving the area. Example below:
Hour of the day | Count into area | Count leaving area |
0 | 2 | 6 |
1 | 3 | 8 |
2 | 4 | 0 |
3 | 0 | 0 |
4 | 6 | 0 |
5 | 0 | 2 |
6 | 0 | 1 |
7 | 5 | 3 |
Thank you in advance,
Step 0: I use these data.
Step 1: I add a 'Date' column on Power Query Editor.
- Before -
- After -
Step 2: I add a 'Time' column on Power Query Editor.
- Before -
- After -
Step 3: I change the type of 'Time' column.
'Time' column: 'Time' --> 'Decimal Number'
Step 4: I add a 'Hour' column below.
Step 5: I change the type of 'Hour' column.
'Hour' column: 'Decimal Number' --> 'Whole Number'
Step 6: I click 'Close & Apply'.
Step 7: I make a matrix on Power BI Desktop.
Hi @KRD - Create a calculated table and in your dataset hope you have hour in and out columns.
HourlySummary =
VAR IntoCounts =
SUMMARIZE (
'YourTableName',
'YourTableName'[Into Hour],
"Count Into Area", COUNTROWS('YourTableName')
)
VAR OutCounts =
SUMMARIZE (
'YourTableName',
'YourTableName'[Out Of Hour],
"Count Leaving Area", COUNTROWS('YourTableName')
)
RETURN
ADDCOLUMNS (
GENERATESERIES (0, 23, 1),
"Count Into Area",
COALESCE (LOOKUPVALUE (
IntoCounts[Count Into Area],
IntoCounts[Into Hour],
[Value]
), 0),
"Count Leaving Area",
COALESCE (LOOKUPVALUE (
OutCounts[Count Leaving Area],
OutCounts[Out Of Hour],
[Value]
), 0)
)
