Show all items in X axis

Hi AlB  and Greg_Deckler,

my next try, maybe you will find a bug in my solution and will be more successful than I was.

My next idea is to use Report Themes - create a new JSON file with a report theme and apply it to every report. According https://docs.microsoft.com/en-us/power-bi/desktop-report-themes it is possible to set all column charts to categorical or continuous (check the JSON file at the end of the MS doc page). I've tried to set many different properties, they worked but setting axisType for categoryAxis didn't. 

Do you have any idea why the following JSON theme doesn't work?

{
    "name": "My Theme",
    "visualStyles": {
        "columnChart": {
            "*": {
                "categoryAxis": [
                    {
                        "axisType": "Categorical",
                        "fontSize": 14
                    }
                ]
            }
        }
    }
}
