13 13  Starting with //**tvb-widgets 1.5.0**, //the TS widget comes in 2 forms, corresponding to the 2 different libraries (we called them backends) used for plotting: **matplotlib **and **plotly**. The matplotlib backend, build on top of the **mne** library, offers more advanced scientifical features, while the plotly backend has a more appealing look and moves faster when talking about the basic interactions.

119 +To modify the spacing between the channels, go with your cursor over the beginning/end of the Y axis (where the channels list is) and drag it to the outside of the plot area. To decrease the spacing, drag your cursor to the inside of the plot area. To reset the spacing to the default values, click on the 'Reset axes' button (Home icon) from the plotly tools area.
