1		-== Purpose ==
2		-
3		-It is a Jupyter widget intended for the visualization of brain signals represented as time series.
4		-
5		-== Inputs ==
6		-
7		-Time series can be given as inputs in two forms:
8		-
9		-* TVB TimeSeries datatype
10		-* Numpy arrays
11		-
12		-This widget supports 2D, 3D, and 4D arrays. In all three cases, there is a fixed shape that the TimeSeries widget expects:
13		-
14		-* for **2D**: (no_timepoints, no_channels)
15		-* for **3D**: (no_timepoints, state_variable/mode, no_channels)
16		-* for **4D**: (no_timepoints, state_variable, no_channels, mode)
17		-
18		-~* Note that the TVB TimeSeries datatype is always 4D and already has the expected shape.
19		-
20		-== Requirements and installation ==
21		-
22		-Before installing the tvb-widgets library containing the TimeSeries widget, the following python libraries and Jupyter extensions should be installed:
23		-
24		-* **Libraries:**
25		-** [[ipympl>>https://github.com/matplotlib/ipympl#installation]]
26		-* (((
27		-**Extensions:**
28		-
29		-(% class="box" %)
30		-(((
31		-jupyter labextension install @jupyter-widgets/jupyterlab-manager
32		-
33		-jupyter labextension install jupyter-matplotlib
34		-)))
35		-)))
36		-
37		-Then, to install the tvb-widgets library, just type:
38		-
39		-(% class="box" %)
40		-(((
41		-pip install tvb-widgets
42		-)))
43		-
44		-== API usage ==
45		-
46		-First, the correct matplotlib backend must be set, which enables the interaction with the TimeSeries widget, by running the following command:
47		-
48		-(% class="box" %)
49		-(((
50		-%matplotlib widget
51		-)))
52		-
53		- Then, the **TimeSeriesWidget** (from the tvb-widgets API) and the **//display//** function should be imported:
54		-
55		-(% class="box" %)
56		-(((
57		-from tvbwidgets.api import TimeSeriesWidget
	1	+TODO
	2	+! pip install -i tvb-widgets
	3	+from tvbwidgets.api import TimeseriesWidget
58	58	from IPython.core.display_functions import display
59		-)))
60		-
61		-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):
62		-
63		-(% class="box" %)
64		-(((
65		-tsw = TimeSeriesWidget()
66		-tsw.add_datatype(tsr)
67		-)))
68		-
69		-Finally, to display and interact with the TimeSeries widget, the **//get_widget//**// //method is used inside the //**display **//function:
70		-
71		-(% class="box" %)
72		-(((
73		-display(tsw.get_widget())
74		-)))
75		-
	5	+tw = TimeseriesWidget(...)
	6	+display(tw.get_widget())
