Monitor plots improvements
Add scale to color bar in monitors with bokeh image displays.
On monitor pages like the dark monitor, in the Mean Dark Image tab, the color bar needs a scale to show what the colors actually represent. The image is yellow, but we don't know what yellow means.
Also, the x and y axes are not clear. If they are meant to be rows and columns of an image, a MIRI image is about 1024 by 1024 (1032 with reference pixels). The scale in the image on this page looks like it's a 10x10 pixel region, which doesn't make sense. This should be a bit clearer.
@bourque and @cracraft I found out the yellow square issue. When the DB is empty and there is no data available, a 10x10 array of zeros is generated to take the actual data's place. When the data is uniform, I think bokeh might have a hard time interpreting the values on the color bar.
As a test, I went and changed the from data = np.zeros(10, 10) to data = np.random.rand(10, 10) + 1e3 and obtained this image:
Looks like bokeh templating works well, it is just a data issue. Maybe we can put in the title (empty database table, this is fake data) or something?
It would be ideal if the webpage could just display some sort of "no data available" message instead of rendering a plot altogether, but if that is too complicated/difficult to implement, I think @mfixstsci's solution is a good option.
