一、如何画多个子图组合的图，以及修改标题和曲线名字

目前我还没法解决显示中文的问题

最终效果

效果

要修改的参数

需要设置的地方

核心代码

p1 = plot(x,y,title = "price",label = "price",legend=:topleft)       #图1的内容
p1 = plot!(x,z,label = "commax_price")                                  #图1继续添加内容
p2 = plot(x,hc_ary * (-1),title = "drawdown",label = "hc",legend=:topleft)   #图2的内容
plot(p1,p2,layout = @layout grid(2,1))  #多图组合

全部代码

function draw2(df)
    df = @linq df |> where(Date("2017-01-15") .< :日期 .< Date("2020-06-01"))   
    
    a = df.组合
    cummax_a = cummax(a)                  #累计最高值 
    hc_ary = @.(100 * (a / cummax_a -1))  
    max_hc = minimum(hc_ary)

    x = df.日期    
    p1 = plot(x,a,title = "price",label = "price",legend=:topleft)  
    p1 = plot!(x,cummax_a,label = "commax_price")
    p2 = plot(x,hc_ary * (-1),title = "drawdown",label = "hc",legend=:topleft)
   
    plot(p1,p2,layout = @layout grid(2,1))
end
draw2(res_df)
