Changing the title of a barchart with json (setting up custom theme)

[addd123]

Im using the option to create a custom theme in Json.

I cant seem to find the option to alter the font or fontsize of the title of the graph. 

In the code below i guess it would work putting "title" in the place "legend" but it doesnt. In the documentation (https://powerbi.microsoft.com/en-us/documentation/powerbi-desktop-report-themes/) and in the editor (https://powerbi.tips/tools/report-theme-generator-v3/) I have seen no way to alter the settings for the “title” of the graphs, is it not available yet or am I missing something?

{"name":"My Theme",
	
		"visualStyles":	{

			"barChart":{
                            "*":{   
                                    
                                    "legend":[{"fontSize":9,"fontFamily":"Segoe UI"}],
                                    "categoryAxis":[{"fontSize":10,"fontFamily":"Segoe UI"}],
                                    "valueAxis":[{"fontSize":11,"fontFamily":"Segoe UI"}]
                                }
                            }

                         }
}
