Selected indices are saved in the `ind` attribute. verts = [(0. e. pyplot as plt fig, ax = plt. Polygon Selector# Shows how to create a polygon programmatically or interactively Polygon Selector¶ Shows how one can select indices of a polygon interactively. Download Jupyter notebook: polygon_selector_simple. widgets import PolygonSelector from matplotlib. path import Path class SelectFromCollection : """ Select indices from a matplotlib collection using `PolygonSelector`. widgets import PolygonSelector Select points in the figure by enclosing them within a polygon. widgets import PolygonSelector Click on the figure to create a polygon. Once drawn individual vertices can be moved by clicking and dragging with the left mouse button, or removed by clicking the right mouse button. Place vertices with each mouse click, and make the selection by completing the polygon (clicking on the first vertex). Polygon Selector# Shows how to create a polygon programmatically or interactively import matplotlib. arange(grid_size), grid_si ze) grid_y = np. This lab demonstrates how to use the Polygon Selector tool in Matplotlib to select indices from a scatter plot. , reduces their alpha . path import Path class SelectFromCollection (object): """Select indices from a matplotlib collection using `PolygonSelector`. 1, 0. tile(np. However Matplotlib does provide a mechanism for handling mouse events and we can implement a custom polygon selection functionality using these event-handling capabilities. 9), (0. 3, 0.
