Reduce gap between candles

[barnabee]

Story

As a trader
I want the gaps between candles to be a as small as possible
So that I can see more candles for a given interval

Acceptance Criteria

• There should be a min gap when zoomed out
• There should be a max gap when zoomed in
• The gap should scale between these based on zoom level
• Ensure that the studies underneath the main candles plot align with the candles

I would like to also point out I dont like the new colours...

[Osthumus]

The volume section is way bigger than necessary and not aesthetic. Also the colour saturation seems to be too high (not sure if that's a bad thing).

I was making some screenshots today— I think it'd be great for the initial chart setup to perhaps look something like this (all supported already, just setting zoom and sizes and what's enabled), thoughts?

[Osthumus]

Yes, looks much cleaner. Current size of indicator is too chunky and overwhelming.
User can change it anyways if they wanted bigger size.

See these examples for the candle/bar spacing issue in Pennant. In short, candles should be a fixed spacing apart (looks like 1 or 2 pixels?) regardless of zoom, but Pennant grows the gaps as it grows the bars.

Barney requested to widen the starting gap slightly ... @macqbat can do this with a param.

Re-opening this until we get the full fix in

I think after review with Barney the conclusion is what we actually need is:

• A max gap when zoomed in
• A min gap when zoomed out
• Linear scaling based on zoom in between

Can we achieve this?

I've added new param which determines max gap in pixels (default 2px). Next to the previous parameter, which determines the size of the space in relation to the width of the chart bar, this new one gives us possibility to fully control over dimmension of the gap. This dimmension will be always the smaller of these two. So in high zoomed in chart we will always have max only 2px (or other value given as param) and bars will stop to diverge.
Since everything on candles chart are keep in time units (milisecond), pixels are not really strictly calculated, but converted to miliseconds, hence they could have not always the same dimension like pixels on the page, but difference should be not relevant
