Link table data with measures data and display in a visual

Hi Gruja 

ComparisonTable is a calculated table. A calculated table cannot be filtered by filters or slicers in the report. You can consider its data is static when you interact with the report. 

To have a dynamic result displayed, you need to use a measure to populate the column visual. 

A common practice is to add an additional table which has category values to be displayed on x-axis. For example, table 'DimCategory':

Create measures to calculate the Forecasted value and Actual value separately. For example, 

Forecasted = 
SWITCH(
    SELECTEDVALUE('DimCategory'[Category]),
    "Office Space", [Bürobedarf],
    "Storage Space", [Lagerbedarf], 
    "Laboratory Space", [Gesamt Laborbedarf]
)

Actual = 
SWITCH(
    SELECTEDVALUE('DimCategory'[Category]),
    "Office Space", SUMX(FILTER('Export RDB', 'Export RDB'[DIN277-1] = "NUF2"), 'Export RDB'[Raum - Fläche in m²]),
    "Storage Space", SUMX(FILTER('Export RDB', 'Export RDB'[DIN277-1]  = "NUF4"),'Export RDB'[Raum - Fläche in m²]), 
    "Laboratory Space", SUMX(FILTER('Export RDB', 'Export RDB'[DIN277-1]= "NUF3"), 'Export RDB'[Raum - Fläche in m²])
)

Place the new 'DimCategory' table's [Category] column to X-axis, and place the two new measures to Y-axis. 

Hope this would be helpful.
