86 improve xrd plots

[ka-sarthak]

• Zoom along both axes of XRD line plots.
• Center the title for the plots
• Use 'plotly_white' theme for a white background in plots
• RSM
  • format the axis label
  • format colorbar ticks and title
• Add default name of the result section
• If sample_id is not found in raw file, do not initiate a sample. Pass an empty list to samples instead.
• Add intensity vs q_norm plot in XRD 1D results
• Add plot annotations to XRD 1D results for the following quantities: intensity, two_theta, q_norm

I added the old plot_annotations to generate plots for the quantities. Also, I created an additional quantity index_array which acts as a placeholder for the x-axis in the plots. For instance, the plot for two_theta would be "two_theta vs index_array" rather than "intensity vs two_theta" (as was the case before). The same goes for intensity and q_norm. These plots simply visualize the values of the quantity vector. It's interesting to see that the q_norm plot is slightly curved, while the two_theta plot is straight.

index_array is not defined as a derived quantity nor it is populated by the normalizer. Even so, I found that when it is added as the x-axis for plots in quantities, it acts as if it contains range(0,len(<whatever_quantity>).

The only issue is that display annotation does not work. I set it as

a_display={'visible': False}

for index_array but it still shows up on the GUI. Here's the documentation link I followed: https://nomad-lab.eu/prod/v1/staging/docs/reference/annotations.html#display-annotation-for-quantities

Any idea why this is the case?

Just the small changes from our call

[ka-sarthak]

@hampusnasstrom Thanks for the review over our call.

Here are the changes I made:

• Italicized variables like Intensity, θ, ω, q
• Removed formatting from log symbol, absolute symbol
• Removed bold for q components (perpendicular and parallel) on plot axis
• Changed the zoom from scroll to dragmode for all plots
• Add tooltip for datapoints in the plot using hovermode
