Average,STDEV,count by hour+day of week

Hi, I'm trying to create a bar graph with:

y axis=hour

x axis=the following fields

I have a field that correspond to day of the week.

I'm trying to show in the previous graph (x=hour):

-count for the current day

-average count by day of the week, for those with same day of today (to graph with hour in the x axis)

-STDV by day of the week, for those with same day of today (same as average)

So: Tuesday count by hour, for past tuesdays AVERAGE AND STDV by hour.

I'm trying AVERAGEX fitering by day of the week, but the result have no sense.

Any ideas of where can I start?

thank you!

@alejandrofm,

Create the following measure in your original table.

```Measure = COUNT(Hoja1[codigo])
```

Then create the group table using DAX below. However, could you please describe more details about how you calculate average in Excel? As I notice that there is no 07:30 data for Jueves at 10/11/2018.

`GroupTable = SUMMARIZE(Hoja1,Hoja1[fecha],Hoja1[DiaSemana],Hoja1[Tipo],Hoja1[hora],"Total",[Measure])`

Hi, sorry for the lack of information in previous post, can't attach a file here so here's the google Drive link to excel input/expected result +pbix almost empty, every test I made give wrong results.

There you have the pbix with the excel loaded, the source excel and the expected output in excel:

-Raw has the database data

-In grouped I count records

-In AVG_STDV I calculate the average and DSTV from the current day and the values for today until the hour I extract the data.

-Then in the graph (I don't have much data now so it seems a little ugly but I show: current value, average and 1 standard deviation up and down to the average for each hour.

General idea: to know the normal process function and improve the management of the demand.

Thank you!

Thank you! I didn't know the SUMARIZE function, is like a GROUP BY,

To calculate the average y transform the N/A to 0, but that was because the system was in testing, I will have values for all interval (or I'll se how to fill empty values with "0"), I let that to another fase, I don't thing that will be so simple

thanks!
