2		-! pip install -i tvb-widgets
3		-from tvbwidgets.api import TimeseriesWidget
	1	+== Purpose ==
	2	+
	3	+It is a Jupyter widget intended for the visualization of brain signals represented as time series.
	4	+
	5	+
	6	+== Inputs ==
	7	+
	8	+It supports time series inputs of two types:
	9	+
	10	+* TVB TimeSeries datatype
	11	+* Numpy arrays
	12	+
	13	+The widget supports 2-, 3-, and 4-dimensional arrays. In all three cases, there is a fixed shape that the TimeSeries widget expects:
	14	+
	15	+* for **2D**: (no_timepoints, no_channels)
	16	+* for **3D**: (no_timepoints, state_variable/mode, no_channels)
	17	+* for **4D**: (no_timepoints, state_variable, no_channels, mode)
	18	+
	19	+~* Note that the TVB TimeSeries datatype is always 4D and already has the expected shape.
	20	+
	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
4	4	from IPython.core.display_functions import display
5		-tw = TimeseriesWidget(...)
6		-display(tw.get_widget())
7		-
	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	+)))
	77	+
