Use the Scatterwidget with AnnData from Notebook

This tutorial is an example of how to use the Napari-Spatialdata ScatterWidget from a notebook.

Import packages and data

There are two options to install napari-spatialdata:

(1) Run pip install napari-spatialdata

or,

(2) Clone this repo and run pip install -e .

from napari_spatialdata import QtAdataScatterWidget
import squidpy as sq
import matplotlib.pyplot as plt

Load in the AnnData:

adata = sq.datasets.visium_hne_adata()

The following line is needed to initialize a widget without a QApplication:

%gui qt5

Open the ScatterWidget:

widget = QtAdataScatterWidget(adata)
widget.show()

The widget:

plt.imshow(widget.screenshot())
plt.axis('off')

(-0.5, 861.5, 719.5, -0.5)

Some examples of scatterplots:

plt.imshow(widget.screenshot())
plt.axis('off')

(-0.5, 861.5, 719.5, -0.5)

plt.imshow(widget.screenshot())
plt.axis('off')

(-0.5, 861.5, 719.5, -0.5)
