Add any chart/image to map by DAX

[wujunmin]

How? 

First, you need a SVG map,  you could get them from https://www.amcharts.com/svg-maps/

Download the map and copy the code to Power BI.

Add a new measure, paste the SVG code:

The map could be shown by HTML Content:

Second, you need XY Value for every location.

Third, creat the chart measure: 

Column_Chart_Map= 
VAR MAX_Value =
    MAXX ( ALL ( 'table'[Province] ), [value] )
VAR MAX_Width = 40
VAR FontSize = 12
VAR Chart =
    CONCATENATEX (
        'table',
        "<text  x='" & [坐标轴_X] & "' y='" & [坐标轴_Y] + FontSize + 1 & "' text-anchor='start' font-size='" & FontSize & "' fill='Grey'>" & [Province] & "</text>" &
        "<rect rx='1' x='" & [坐标轴_X] - 5 & "' y='" & [坐标轴_Y] + FontSize + 1 - MAX_Width * [value] / MAX_Value & "'height='" & MAX_Width * [value] / MAX_Value & "'width='5' fill='"
            & IF ( [value] >= 50, "DarkCyan", "Tomato" ) & "'/>"
    )
RETURN
    SUBSTITUTE ( [MAP], "</svg>", Chart & "</svg>" )

Image_Map= 
VAR MAX_Value =
    MAXX ( ALL ( 'table'[Province] ), [value] )
VAR MAX_Width = 40
VAR FontSize = 12
VAR image = "http://*****.com/****.png
VAR imagemap =
    CONCATENATEX (
        'table',
        "<image xlink:href='" & image & "' x='" & [坐标轴_X] & "' y='" & [坐标轴_Y] & "' width='" & MAX_Width * [value] / MAX_Value & "' height='" & MAX_Width * [value] / MAX_Value & "'></image>" & "<text  x='" & [坐标轴_X] & "' y='" & [坐标轴_Y] + FontSize + 1 & "' text-anchor='start' font-size='" & FontSize & "' fill='Black'>" & [Province] & "</text>"
    )
RETURN
    SUBSTITUTE ( [MAP], "</svg>", imagemap & "</svg>" )

Again, you could see the result by HTML content.
