You will need to know the real names of your columns. Most likely you have imported your data from excel into SharePoint.
When you create a list from Excel it will not use the column names from your Excel as the column names in SharePoint, it will generate its own column names (initially).
Once a column is named, it can never be renamed. That is, the "real" name of the column can never be renamed. You can rename in SharePoint, but it is "visual" only. The Real name will not change.
PowerApps works with the Real names for controls like the charts.
The only way to resolve is to build another list and create your columns and name them all manually. Then you can copy your data over from the other and use the new list for your PowerApps.
So, if you stick with the list you have, then you will need to look at the real names of the columns to know which is which. To determine a column's real name, you can click on the column in the List Settings of your list and then in the address bar of your browser, look at the end of the URL - it will show the real name.
As for your Items property of the chart, you will want something more like this:
AddColumns(
GroupBy(
AddColumns(yourDataSource,
"_outageType", Outage_Type.Value
),
"Market", "_outageType", "_data"
),
"_outageCount", CountRows(_data)
)
Now, the above is a general formula (and again, the field names in the above need to be replaced with the Real names), but I am not entirely sure what you are trying to count and how you are trying to display the data.
The above will provide a set of Market and Outage Type records with a count as to the number of records associated with those records.
I hope this is helpful for you.
