Change color based on date slider

Community Support

I am trying to change the fill colors on some square glyps based on a date slider. The colors are based on some values in the ‘data’ param of ColumnDataSource. Is there a way to make the slider values a date and each step be by minute?
From the docs: slider = Slider(start=0.1, end=4, value=1, step=.1, title=“power”, callback=callback)
My markers I am trying to change: p.square(x, y, size = 15, alpha=0.5, source=source, fill_color=colors)
I am trying to see the progression of my scatter objects over a time period with changes in color using CustomJS. Any tips on getting a date selection slider or how to incorporate the fil_color param with callbacks would be greatly appreciated! thanks

You should just need to specify the color change in a callback on
Slider. You can see lots of examples of using callbacks with
sliders in the examples:

Post some code if you can’t get it to work.
