I correct my post.

• The channel name was incorrect. Please use `K1:CAL-CS_PROC_DARM_DISPLACEMENT_DQ`. I attach the example of noise budget  including the current sensitivity.

Future work memo

• Implement the checkbox to tuen on/off the noise curves for `current best` and `O4a target (3Mpc)`.
• Implement the arbitral color options (to keep robustness, the usage will be not so simple)
• Implement the category (group?) appearance in the legend. There are two categories in the legend : refernce and noise budget. By using indent, it might be possible to implement.
