i have on the tablet a MagicMirror installation , where i can show Weather , News etc
also possible to show part of a website scrollable ( i have only about 300px height) , there i want to show Volkszaehler data but plot and data are too much for this height

in Wiki there are the possible config parameter /?hide=#xx for hide some parts of Volkszaehler frontend
When /?hide=#plot is used, you get a java / website error message

Error: Invalid dimensions for plot, width = 0, height = 682 (windows)
java runtime error : uncaught error invalide Dimension for plot widght=0 hight=300 (android)

all other hide funktion works good
