Slowing of ggplot2 and plotly



Hi, all i m here to get some help that, what i have to do if ggplot2 and plotly takes too much time load for large data set. I am fed up but didn't find any proper solution.


How large is your dataset, and which kind of graph are you trying to plot?


I have list of customer about 100000, i am trying to plot scatter plot.


Welcome to!

There are a number of ways you might speed up your code. A good way to get specific advice on this is to provide a reproducible example (what folks usually refer to as a reprex) of your problem, data and code. (And I'd suggest offering a smaller, but representative dataset to start with).

In terms of general strategies to speed up your R-code (or any code for that matter), I would suggest checking out @csgillespie's "Efficient optimisation" chapter from "Efficient R programming". If you can overlook his (British) misspellings of optimisation, there's a wealth of good advice there.

Given the limited info about the issue so far, and just some ideas; I might work through

  • data loading, can you load your data faster? perhaps via a database?
  • are there computationally costly operations that can be avoided or optimized?
  • can you benefit from parallelisation?
  • can you reduce how much data your visualization needs to plot (eg smoothers or densities)?


Thanks a lot, in fact i am developing an R visual for power BI reporting, I developed it, but it's too slow. even I used BW theme.


Can you share some code? I find it odd that you experience that, as I for example work with 8 billion entries and it's rather fast.


It is surprising that ggplot cannot handle such small data. Can you provide your computer hardware info and structure of data?


this is the code:
names(Values)<-gsub('/','',gsub(' ','',names(Values))); #Values is the list of measures passed in power BI to that visual.
n<- names(Values)
value1<-eval(parse(text = st1));
value2<-eval(parse(text = st2));
value3<-eval(parse(text = st3));
base_p <- qplot(Values, aes(x=value3, y=value2,text=paste(st1,": ",value1)));
g= base_p + geom_pointr() +theme_classic()+ theme(legend.position="none") + labs(x = gsub('Values$','',st3),y = gsub('Values$','',st2));
p = ggplotly(g);
internalSaveWidget(p, 'out.html');


I believe that the problem here is not related to plotting but to the gsub and paste functions. I would try to opt for stringr or similar packages instead.
Also it's not optimal at all to include gsub functions on your gplot part. This section below for example is something avoid. Save the x as an object and you'll see that it will be faster.

I also don't really understand why do you run the plotly function on a ggplot object. It would be easier to simply run plot_ly, and the objects you want to plot.

In the overall this is not about ggplot or plotly but with the fact that you have too much stuff going around. Avoid gsub functions, and do not include them on the ggplot's arguments.


Ok Thanks alot I'll give you feed back soon.
