21		-== Requirements and installation ==
22		-
23		-Before installing the tvb-widgets library containing the TimeSeries widget, the following python libraries and  Jupyter Notebook extensions should be installed:
24		-
25		-* **Libraries:**
26		-** [[ipympl>>https://github.com/matplotlib/ipympl#installation]]
27		-* (((
28		-**Extensions:**
29		-
30		-(% class="box" %)
31		-(((
32		-jupyter labextension install @jupyter-widgets/jupyterlab-manager
33		-
34		-jupyter labextension install jupyter-matplotlib
35		-)))
36		-)))
37		-
38		-Then, to install the tvb-widgets library, just type:
39		-
40		-(% class="box" %)
41		-(((
42		-pip install tvb-widgets
43		-)))
44		-
45		-
46		-== API usage ==
47		-
48		-First, the correct matplotlib backend must be set, which enables the interaction with the TimeSeries widget, by running the following command:
49		-
50		-(% class="box" %)
51		-(((
52		-%matplotlib widget
53		-)))
54		-
55		- Then, the TimeSeries widget (from the tvb-widgets API) and the display function should be imported:
56		-
57		-(% class="box" %)
58		-(((
59		-from tvbwidgets.api import TimeSeriesWidget
60		-from IPython.core.display_functions import display
61		-)))
62		-
63		-Assuming that the user has already created or imported a valid input, this is how the widget can be initialized and how an input can be assigned to it, using the //**add_datatype** //method (example below assumes that **//tsr//  **is a TVB TimeSeries datatype):
64		-
65		-(% class="box" %)
66		-(((
67		-tsw = TimeSeriesWidget()
68		-tsw.add_datatype(tsr)
69		-)))
70		-
71		-Finally, to display and interact with the TimeSeries widget, the **//get_widget//**// //method is used inside the //**display **//function:
72		-
73		-(% class="box" %)
74		-(((
75		-display(tsw.get_widget())
76		-)))
