you can reset the ydata using:

ydata += 50
myline.set_ydata(ydata) # pass new data to line object
Does this work for you?
Yes. Altough I dont understand why I have to set it again (the ydata
still belong to the curve)
Thanks,

Hi Ole,
I think the ydata of the line is updated, but the plot is not updated. To
achieve the latter, you need to use set_ydata. I'm sorry if this was your
original question and I didn't get this.
From the source code of set_data another way seems to be possbilbe - although
quite strange:
ydata += 50
# setting the line invalid in order to force a redraw during draw
myline._invalid = True
draw()
Maybe someone else has an idea about that.
regards Matthias

The when you use set_data, the widget is aware the data has changed and sets its _invalid member to True, which triggers a full redraw. When you just modify the array, the line object isn’t aware that the data has changed, and thus just redraws from its (I believe) cached version.
