Is it possible to draw polylines with points from a JSON string like in Android Classic?
If so, how?
Thanks for any help!
Yes. Will it work?
Thanks, I saw that block, but the text block doesn’t connect to that.
Why do you need to connect a text block to this block? A list with coordinates or a variable with the desired data type can be connected to this block.
There are about 350 points in the polyline. I don’t want to enter them one by one, but in a Json string.
From the text string, you can create a list of data in the required format.

I think I get it, thanks. Will report back here with the result.
Now I feel like an idiot. 
There seems to be no ‘create list with’ block… There is only the create list with repeated items block.
To improve your mood, a simple example with JSON data for a polyline. 
I also show the magic of turning a string into a numeric type.

That’s fantastic. Thanks for your help!
OT: it’s strange how the json format differs. In Android Classic only [[mydata],[otherdata]] will work, not [{mydata},{otherdata}]
Yes, in Thunkable X uses an array of objects, and Thunkable Classic uses a multi-dimensional array.
