Improve the pdos plot

[superstar54]

Ensure band plot is the same when combined with PDOS or when not combined (combined looks better). See also other issue being discussed by C&G. In particular, have horizontal line at Fermi level.

Default PDOS zoom/scaling: for the starting one, scale PDOS max value only in visible range (if you do PDOS of gold, it’s very tiny because, out of scale, there are the semicore p levels). Only use the max pdos from the home.

Default zoom: PDOS look tiny. I would do zoom within the visible range.

If I do autoscale, I see why - semicore p at ~-60eV.

PDOS selectors:

• Do not require ‘update plot’ button. If you want it only for the text box ‘select atoms’, move button to the right and call it ‘apply’, only for select atoms.
• In select atoms, leave in gray an example of the syntax, e.g. “1,2,4-6” or similar
• Do not sum “1s” and “2s”
• Change “Update plot” to “apply selection”. And selection from the dropdown should affect immediately.
