45 -== API usage ==

47 -First, the correct matplotlib backend must be set, which enables the interaction with the TimeSeries widget, by running the following command:
48 -
49 -(% class="box" %)
50 -(((
51 -%matplotlib widget
52 -)))
53 -
54 - Then, the **TimeSeriesWidget** (from the tvb-widgets API) and the **//display//** function should be imported:

56 -(% class="box" %)
57 -(((
58 -from tvbwidgets.api import TimeSeriesWidget
59 -from IPython.core.display_functions import display
60 -)))
61 -
62 -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):
63 -
64 -(% class="box" %)
65 -(((
66 -tsw = TimeSeriesWidget()
67 -tsw.add_datatype(tsr)
68 -)))

70 -Finally, to display and interact with the TimeSeries widget, the **//get_widget//**// //method is used inside the //**display **//function:

72 -(% class="box" %)
