Hi Leute,

ich hab mir heute ein mini Script gebaut um mir Graphen usw als Bild an Telegram schicken zu lassen.

Bis jetzt funktioniert das soweit prima.

Was ist zutun?

• apt install cutycapt
• apt-get install xvfb
• DP erzeugen (String)
• Blockly importieren
• DP mit gewünschter URL füllen

Ich hoffe ich konnte damit jemandem helfen.
