| 5 | == Purpose == | ||
| 6 | |||
| 7 | It is a Jupyter Widget intended for the visualization of the interactive phase-plane. | ||
| 8 | |||
| 9 | It provides sliders for setting: | ||
| 10 | |||
| 11 | * ((( | ||
| 12 | The value of all parameters of the Model. | ||
| 13 | ))) | ||
| 14 | * ((( | ||
| 15 | The extent of the axes. | ||
| 16 | ))) | ||
| 17 | * ((( | ||
| 18 | A fixed value for the state-variables which aren't currently selected. | ||
| 19 | ))) | ||
| 20 | * ((( | ||
| 21 | The noise strength, if a stochastic integrator is specified. | ||
| 22 | ))) | ||
| 23 | |||
| 24 | and dropdown lists for selecting: | ||
| 25 | |||
| 26 | * ((( | ||
| 27 | Which state-variables to show on each axis. | ||
| 28 | ))) | ||
| 29 | * ((( | ||
| 30 | Which mode to show, if the Model has them. | ||
| 31 | ))) | ||
| 32 | |||
| 33 | Entering the coordinates in the X,Y Coordinate Boxes will generate a sample | ||
| 34 | trajectory, originating from the coordinates entered. | ||
| 35 | |||
| 36 | == Inputs == | ||
| 37 | |||
| 38 | Phase-Plane viewer will be represented in the beginning based on the parameters that it receives: | ||
| 39 | |||
| 40 | * Model (Generic2dOscillator, Epileptor, Hopfield, etc.) | ||
| 41 | * Integrator (HeunDeterministic, HeunStochastic, Identity, etc.) | ||
| 42 | |||
| 43 | == Requirements and installation == | ||
| 44 | |||
| 45 | Before installing the tvb-widgets library containing the PhasePlane widget, the following python libraries and Jupyter extensions should be installed: | ||
| 46 | |||
| 47 | * **Libraries:** | ||
| 48 | |||
| 49 | [[ipympl>>https://github.com/matplotlib/ipympl#installation]] | ||
| 50 | |||
| 51 | * **Extensions:** | ||
| 52 | |||
| 53 | (% class="box" %) | ||
| 54 | ((( | ||
| 55 | jupyter labextension install @jupyter-widgets/jupyterlab-manager | ||
| 56 | |||
| 57 | jupyter labextension install jupyter-matplotlib | ||
| 58 | ))) | ||
| 59 | |||
| 60 | Then, to install the tvb-widgets library, just type: | ||
| 61 | |||
| 62 | (% class="box" %) | ||
| 63 | ((( | ||
| 64 | pip install tvb-widgets | ||
| 65 | ))) |
