Plot Times Series of Sentiment by Company in R -


i make sentiment analysis in r. in have dataset column "svolume" values 1,5,41,... column different names of company. last column dates yyyy-mm-dd.

i plot times series dates each company, if have 3 company, have 3 lines, on x axis dates, , y axis svolumes.

i wrote :

data2=data[order(as.date(data$date, format="%d/%m/%y")),]

in order order data dates.

plot.ts(data2$svolume) axis(1,1:40,data2$date)

and plot time serie of svolumes , put dates on x axis. have 2 problems: have 1 line can't see difference between 3 company (i love have line of total if possible), , second problem it's impossible read dates there horizontal , wrote 1 on each others. there way write dates verticaly example in order read it?

i have plot this: times series plot 1 instead of "websites" have "volumes" , instead of "shoes,socks,lace" have name of companies/subjects

or svolumes time series plot 2

that's how data looks like:
