I don't think that's possible, widgets have a limited set of views, the tutorial to create widgets can be found HERE

You can draw chart on bitmap canvas and show it on imageview

Click to expand...

You might be able to do it using the BroadcastReceiver library.

@urikupfer: how does it work? is that like building a bitmap image and saving it? i think that will wear down the flash storage very quick.

i think it is called a simple line chart. it must be updated round about every 5minutes

yes, this will work for me! :sign0060:

but i have a question about that timer. it is set to 1000 ms (equals 1 sec), but i just want an update of the chart every 5 or 10mins, so i can do it just by setting the minutes in the configurehomewidgets and kick the timer away - right?

is the bitmap/canvas just inside my tablets RAM or is it stored and rewritten on and on inside the flash memory?

I think that The bitmap is in the ram, anyway it`s small.
I put 1000 ms in the timer just for the sample. You can change it, but according the widget configuration help the smallest time is 30 min.
