我是一个相对较新的 Julia 编码器，我想在一个循环中绘制多个 Gadfly 图并将它们保存为 pdf。
如果我在没有循环的情况下执行此操作，仅针对一个块，代码如下：
plot(x=[0, B_length[2,1,1],B_length[2,1,1],0],
y=[0,0,1,1],
layer(x=[B_length[2,1,1]/2], y=[0.5], label=[string("Spec: ", string(K_names[Kblock1[1]]))], Geom.label(position=:centered)), #specialty label for block 1
layer(x=[B_length[2,1,1]/2], y=[4.5], label=[string("Surgeon: ", string(S_names[Sblock1[1]]))], Geom.label(position=:centered)), #surgeon label for block 1
layer(x=[B_length[2,1,1]/2], y=[2.5], label=[string("No. P = ", string(Pblock1), " L = ", string(Lblock1))], Geom.label(position=:centered)), #number of patients and emergency
layer(x=[0, B_length[2,1,1],B_length[2,1,1],0],y=[4,4,5,5], #Surgeon - Block1
Geom.polygon(fill=true),
Theme(default_color=color("#00CCCC"))),
layer(x=[0, block2pt_end,block2pt_end,0],y=[2,2,3,3], #Patient and Emergency - Block1
Geom.polygon(fill=true),
Theme(default_color=color("gray"))),
Geom.polygon(preserve_order=true, fill=true))
并生成此图：
当我返回并用它们的变量替换值并在循环中构建时，我有以下代码：
for i=1:I
for r=1:R
B2used = sum(x_blockval[i, :, 2, r])
if (B2used >= 1)
k_block2[i,r] = findfirst([x_blockval[i,k,2,r] for k=1:K]) #block=1
s_block2[i,r] = findfirst([x_sval[r,i,2,s,k_block2[i,r]] for s=1:S])
p_block2[i,r] = x_pval[r,i,2,k_block2[i,r]]
l_block2[i,r] = x_lval[r,i,2,k_block2[i,r]]
block2pt_end[i,r] = F_lμ[k_block2[i,r]] + F_lσ[k_block2[i,r]]
println("Block 2 used on Day ", i, ", Room ", r, ", Specialty = ", k_block2[i,r], ", Surgeon = ", s_block2[i,r], ", num emergent patients = ", p_block2[i,r], ", num emergency patients = ", l_block2[i,r], ", end time of surgery = ", block2pt_end[i,r])
plot(x=[0, B_length[r,i,2],B_length[r,i,2],0],
y=[0,0,1,1],
layer(x=[B_length[r,i,2]/2], y=[0.5], label=[string("Spec: ", string(K_names[k_block2[i,r]]))], Geom.label(position=:centered)), #specialty label for block 1
layer(x=[B_length[r,i,2]/2], y=[4.5], label=[string("Surgeon: ", string(S_names[k_block2[i,r]]))], Geom.label(position=:centered)), #surgeon label for block 1
layer(x=[B_length[r,i,2]/2], y=[2.5], label=[string("No. P = ", string(p_block2[i,r]), " L = ", string(l_block2[i,r]))], Geom.label(position=:centered)), #number of patients and emergency
layer(x=[0, B_length[r,i,2],B_length[r,i,2],0],y=[4,4,5,5], #Surgeon - Block1
Geom.polygon(fill=true),
Theme(default_color=color("#00CCCC"))),
layer(x=[0, block2pt_end,block2pt_end,0],y=[2,2,3,3], #Patient and Emergency - Block1
Geom.polygon(fill=true),
Theme(default_color=color("gray"))),
Geom.polygon(preserve_order=true, fill=true))
end
end
end
但它不会产生任何图表。理想情况下，我想将所有图表保存在 pdf 中。我知道我可以使用'draw（PDF（“filename.pdf”，6inch，9inch），vstack（p 1，p [2]）'或类似的东西......
