Description
I've been using MPL finance for quite some time now, everything is flawless and i'm impressed by the new features!
I'm trying to fix a problem that has to do with Matplotlib itself too: once i add to my chart two horizontal lines that are far from the last price, the candles will get compressed and the chart becomes harder to read. Now i know that this happens because of the horizontal lines, but i was wondering if there is some way/method/function to scale the chart so that the candles stay less compressed while keeping the lines. Thanks in advance!
```
fig, axlist = mpf.plot(df, type='candle', figscale=2, figratio=(50, 50), style=s, returnfig=True)
ax1 = axlist[0]
ax1.axhline(8000)
ax1.axhline(14000)
```

Research direction
No repository file or test is named. Start by reproducing the supplied mpf.plot example and inspect the relevant Matplotlib axis-scaling behavior; done would require a clearly defined, supported way to keep the horizontal lines while avoiding unreadable candle compression.
