Description
Hi,
I appreciate your work!
How would I plot multiple candles together side by side on the same figure?
I want to compare 1. original data, 2. modified data side by side.
So for each x value there will be 2 candles.
My first attempt was scale the width and maybe offset each candle to the side. But I could not find any option to do that.
It would be nice to have horizontal_offset keyword to place candles offset from the centre. Is what I want to achieve possible?
Hopefully I want to achieve the same with volume plot too.
If it is not possible, how about having two separate scale width for each? The candles will still be overlapped but at least they can be distinguished.
`plot2 = fplt.make_addplot(data2,type='candle')`
`fplt.plot(data, type='candle', style=s, volume=True, addplot=plot2, scale_width_adjustment=dict(candle=0.5))`

Research direction
Start with the fplt.make_addplot and fplt.plot calls shown in the issue, then trace how candle addplots and scale_width_adjustment are handled. Define and implement a supported way to display original and modified candles side by side, including the requested volume behavior, and verify that both datasets are visibly distinguishable.
