Fix colour scale for adjuster plots

[zakwatts]

Currently on the adjuster page, the values have largely differing scales which can make it difficult when comparing charts.

Firstly it would be good to have a scale that is centred around the value 0.

We could also fix the scale so that -3500 to 0 could be one colour that gets more intense the more negative the value is. And then likewise for 0 to +3500 in the positive direction.

Theres plenty of different options for what we could do here in terms of colour choices, but I think keeping it simple would be good.

The RdBu could work well. This colour scale could be introduced here

It would be also useful to add that a note on the adjuster page to say that the adjuster values are taken away from the forecast. (So positve adjuster values will reduce the forecast).

Hi @peterdudfield @zakwatts
Could you please assign this to me.
i would like to work on this.
Thank you!

Perhaps even using the ocf colour scheme would be good - https://coolors.co/p/KMrlGnOQMc3Q15XXXCMe

@ram-from-tvl do you know where to change the code for this?

[ram-from-tvl]

I was thinking the same thing, @peterdudfield. Shall I make these changes in adjuster.py ..?

[peterdudfield]

That would be great @ram-from-tvl - thank you.

Just flagging this in case it got lost — looks like feedback was provided earlier and the PR has been open for a while.

Happy to leave this as-is, close it, or reassign if that makes sense. Up to you 👍

I am working on this. Please give me one day. I am finalising on the PR raised.
Thank you!
