I am trying to build a multi-dimensional image viewer using Panel and Bokeh and I would like to provide a slider to modify the scale of the intensities shown on the image.
For this, I would need to modify the color mapper of the Bokeh figure image. I first tried to set the argument
fig.image to a string
color_mapper so I could set it in a
ColumnDataSource but it does not work.
Is that possible to set a new color mapper attached to a Bokeh image? Or even better to modify the high and low parameters (avoiding the unnecessary recreation of the color mapper object).
The same question also applies to the palette used in the
ColorMapper . That would be nice to be able to ‘dynamically’ modify it.
