Tradingview上两个指标代码合并后无法同时显示（一个正常显示一个被缩小到看不到）

在Tradingview上两个指标代码合并后，，无法同时显示（一个正常显示一个被缩小到看不到）。代码小白求助大佬帮忙

两个指标：乖离率的指标和MACD指标两个指标结合在一起。

代码如下.

//@version=4
study("price divergence"  title="MACD", shorttitle="MACD", resolution="")
cs=(close-ema(close,20))/ema(close,20)*100
sm=(ema(close,20)-ema(close,60))/ema(close,60)*100
ml=(ema(close,60)-ema(close,120))/ema(close,120)*100
plot(ml,"ml",color.silver,linewidth=3,style=plot.style_histogram)
plot(sm,"sm",color.black)
plot(cs,"cs",color.red)
plot(cs, title="KG", style=plot.style_area, color=(cs<=0 ? color.red : color.blue ), transp=70 )
plot(0, color=color.black, transp=0, title="Zero")

// Getting inputs
fast_length = input(title="Fast Length", type=input.integer, defval=12)
slow_length = input(title="Slow Length", type=input.integer, defval=26)
src = input(title="Source", type=input.source, defval=close)
signal_length = input(title="Signal Smoothing", type=input.integer, minval = 1, maxval = 50, defval = 9)
sma_source = input(title="Simple MA (Oscillator)", type=input.bool, defval=false)
sma_signal = input(title="Simple MA (Signal Line)", type=input.bool, defval=false)
// Plot colors
col_grow_above = #26A69A
col_grow_below = #FFCDD2
col_fall_above = #B2DFDB
col_fall_below = #EF5350
col_macd = #0094ff
col_signal = #ff6a00
// Calculating
fast_ma = sma_source ? sma(src, fast_length) : ema(src, fast_length)
slow_ma = sma_source ? sma(src, slow_length) : ema(src, slow_length)
macd = fast_ma - slow_ma
signal = sma_signal ? sma(macd, signal_length) : ema(macd, signal_length)
hist = macd - signal
plot(hist, title="Histogram", style=plot.style_columns, color=(hist>=0 ? (hist[1] < hist ? col_grow_above : col_fall_above) : (hist[1] < hist ? col_grow_below : col_fall_below) ), transp=0 )
plot(macd, title="MACD", color=col_macd, transp=0)
plot(signal, title="Signal", color=col_signal, transp=0)
