Matplotlib plt.imshow Parameters Guide

The parameters for the plt.imshow function are as follows:

1. X: Image data to be displayed. It can be a numpy array or a PIL image object.
2. cmap: Color mapping. Default value is None, which uses the default color mapping.
3. Normalization: A process to standardize data. The default value is None, indicating no normalization is performed.
4. Aspect ratio: The default value is ‘equal’, maintaining equal aspect ratio. It can also be set to ‘auto’ for automatic adjustment of the aspect ratio.
5. Interpolation: A method of filling in missing data points. The default value is None, which uses the default interpolation method. Common options include ‘nearest’ (nearest neighbor interpolation), ‘bilinear’ (bilinear interpolation), and ‘bicubic’ (bicubic interpolation).
6. Alpha: Transparency. The default value is None, which means it is opaque. It can be set to a value between 0 and 1 to indicate the degree of transparency.
7. vmin: The minimum value for the color mapping. By default, it is set to None and will use the minimum value of the image data.
8. vmax: The maximum value for the color mapping. The default value is None, which uses the maximum value from the image data.
9. The origin of the image coordinates. The default value is ‘upper’, meaning the origin is in the top left corner of the image. It can also be set to ‘lower’, with the origin in the bottom left corner of the image.
10. Extent: The boundary of the image. By default, it is set to None, using the full range of the image data. It can be set as a tuple (xmin, xmax, ymin, ymax) to specify the range of boundary to display.
11. Filter normalization: Normalizes the filter. The default value is True, which applies the interpolation method to the image data. If set to False, the interpolation method will not be applied.
12. Filter radius: The default value is 4.0 and is only effective when the interpolation method is ‘antialiased’.
13. Resample: A method used for resampling. The default value is None, which means the default resampling method will be used. Common methods include ‘nearest neighbor’ and ‘bilinear’.
14. URL: Image link. The default value is None, meaning no link will be added.
15. **kwargs: Additional keyword arguments. Can be used to set properties such as coordinates, titles, etc.
