Hi … i used to use this code in r studio to generate individual plots for each id and save them as combined pdf for the offline evaluation. can someone help me to translate code to julia.

```julia
pdf("path\\indplots.pdf")
for(i in unique(df$ID))
{
  print((ggplot(subset(df,df$ID == i),aes(x=TAD,y=DV))+
           geom_point()+
           xlab("TAD (hrs)")+
           ylab("Plasma concentration (mg/L)")+
           ggtitle(paste(as.character(i)))+
           theme(panel.grid.minor=element_blank(),
                 panel.grid.major=element_blank(),
                 panel.background = element_blank(),
                 plot.title=element_text(hjust=0.5),
                 legend.position="right",
                 legend.key=(element_rect(colour='white',fill='white')),
                 plot.margin=unit(c(0.5,0.5,0.5,0.5),"cm"),
                 legend.text=element_text(colour="black",size=10),
                 axis.text.x=element_text(colour="black",size=10),
                 axis.text.y=element_text(colour="black",size=10),
                 axis.title=element_text(colour="black",size=14),
                 axis.line.x = element_line( colour="black",size=1,linetype ="solid"),
                 axis.line.y = element_line( colour="black",size=1,linetype ="solid"))))
}
dev.off()

```

here i am focusing more on saving the individual plots as combined pdf ,than the codes to customise plot.  
Thanks.

It is tested on Linux, OS X, and Windows and does not require (manual) installation of external tools. Besides simple installation, it provides a convenient way to produce a PDF file containing multiple plots on different pages.

That would be a `GR` solution:

```julia
using GR
beginprint("plots.pdf")
for i in 1:10 plot(randn(10,4)) end
endprint()

```

`Plots.jl` doesn’t support it natively. But you can trick `Plots`:

```julia
using Plots

Plots.GR.beginprint("plots.pdf")
gr(show=true)

for i in 1:10 plot(randn(10)) end

Plots.GR.endprint()

```

Not very pretty, but works.

Please use the following:

No, that was not the idea. You probably forgot to restart Julia and “used” both GR and Plots, which cannot work.

Thank you, it works now.  
my purpose is to get a separate for each indiviadul . but this code gives me a plot od all values in single page . please rectify the code  
this is the code i have used

```julia
df = DataFrame(id = 1:5, a = 10:14, b = 5:9)
Plots.GR.beginprint("plots.pdf")
gr(show=true)
for i in df.id GR.plot(df.a,df.b) end
Plots.GR.endprint()

```

i want df.a vs df.b plot for each id in a separate pages of pdf file.  
Thank you

for i in df.id plot(df.a,df.b .* i) end
Plots.GR.endprint()

```

The result is **one** PDF with **5** pages.

Are you in a notebook? Did you really restart the Julia kernel? Or, do you “auto-load” packages in your startup files?

this worked after changing the plot to Plots.plot.  
but all the 5 pages have same plot.  
plot i want is ,  
10 on x , 5 on y for id 1 in first page,  
11 on x , 6 on y for id 2 in second page  
.  
.  
14 on x , 9 on y for id 5 in last page.

just plots for individual id’s.

is there a way to get that. Thank you

thank you very much for your support.

can you say , how you got plots.  
each id was printed in separate page ?
