i am taking data from my server and database. and each time i update my database manually but my sketch data is not update and its running previous data in loop.
i want that if i change or update database then my sketch data is automatic update when sketch is complete run .
i want use redraw(); but i don’t know how to use it and where is use it.

Hey. Can you post some code so we can see where the problem is?
To redraw(): It only sets a “flag” that the sketch has to be redrawn. It is not redrawn immediatly.
Where do you call it?

in the draw() function at last

Calling redraw in draw can lead to problems. Maybe this could be one error

You could try to move everything but the connection to the database inside draw. From there you can update the scetch and dont have to call redraw
