49		-== API usage ==
50		-
51		-First, the correct matplotlib backend must be set, which enables the interaction with the TimeSeries widget, by running the following command:
52		-
53		-(% class="box" %)
54		-(((
55		-%matplotlib widget
56		-)))
57		-
58		- Then, the **TimeSeriesWidget** (from the tvb-widgets API) and the **//display//** function should be imported:
59		-
60		-(% class="box" %)
61		-(((
62		-from tvbwidgets.api import TimeSeriesWidget
63		-from IPython.core.display_functions import display
64		-)))
65		-
66		-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):
67		-
68		-(% class="box" %)
69		-(((
70		-tsw = TimeSeriesWidget()
71		-tsw.add_datatype(tsr)
72		-)))
73		-
74		-Finally, to display and interact with the TimeSeries widget, the **//get_widget//**// //method is used inside the //**display **//function:
75		-
76		-(% class="box" %)
77		-(((
78		-display(tsw)
79		-)))
