scatterPlot
Short Description
The scatterPlot function can be used to create scatter plots of single-cell spatial data. This function can be used to visualize the spatial distribution of positive cells for a given marker, providing a quick and intuitive way to view the final predictions.
Function¶
scatterPlot(csObject, markers=None, cspotOutput='cspotOutput', x_coordinate='X_centroid', y_coordinate='Y_centroid', poscellsColor='#78290f', negcellsColor='#e5e5e5', s=None, ncols=5, alpha=1, dpi=200, figsize=(5, 5), invert_yaxis=True, outputDir=None, outputFileName='cspotPlot.png', **kwargs)

Example
# Prohect directory
projectDir = '/Users/aj/Documents/cspotExampleData'
# path to the final output
csObject = '/Users/aj/Desktop/cspotExampleData/CSPOT/cspotOutput/exampleImage_cspotPredict.ome.h5ad'
# Plot image to console
cs.scatterPlot(csObject,
markers=['ECAD', 'CD8A', 'CD45'],
poscellsColor='#78290f',
negcellsColor='#e5e5e5',
s=3,
ncols=3,
dpi=90,
figsize=(4, 4),
outputDir=None,
outputFileName='cspotplot.png')
# Same function if the user wants to run it via Command Line Interface
python scatterPlot.py --csObject /Users/aj/Desktop/cspotExampleData/CSPOT/cspotOutput/exampleImage_cspotPredict.ome.h5ad --markers ECAD CD8A --outputDir /Users/aj/Desktop/cspotExampleData/CSPOT
