Try to get two values (outside temperature and wind speed) in one chart. It works with single charts (One for temp and one for speed) but not combined together.
#Items
Group gChartTempWind
Number WS_Aussentemperatur "Außentemperatur [%s °C]" <temperature> (gChartTempWind) {knx="<9.001:6/6/10"}
Number WS_Wind_km "Wind speed [JS(windspeed.js):%s]" <wind> (gChartTempWind) {knx="<9.005:6/6/30"}
Number Weather_Chart_Period

Here is the result.
