Hi. I have a single image (numpy array) that I wish to display at several points on my figure. I initially tried providing the array in the image parameters along with a source CDS for the X and Y locations but it didn’t like that stating that it was expecting the image to also be in the source. So now I’ve added the image array to each row in the CDS, the key to which is now used in the image parameterisation along with X and y. This works, but it does mean I’ve increased the html filesize unnecessary through duplicating my array.
Therefore my question- is there a way I can plot images but make it share the image array for each location I want to plot it at, in order to save memory/simplify the code? I didn’t really want to have a separate file somewhere in order to use the imageURL method.
Thanks in advance for any help, may well just be me getting something wrong.
