Contrary to your comment, questions that are only about how to use
ggplot2) are off topic here, whether for visualization or analysis or other purposes, and are regularly closed as such. The same is true for questions that are only about how to use
SAS, etc. A question such as, 'should I use barplots or boxplots for these data' is about data visualization, and is on topic here. A question like 'how to I make a barplot in seaborn' is not about data visualization, it is about how to use seaborn. Such questions can be on topic on Stack Overflow and regularly get good answers there.
I think this policy is applied consistently across software. Examine the questions listed under the ggplot2 tag. When viewed in the newest tab, you will see that all of the most recent 8 questions have been closed. But what about a question like: Visualizing highly dimensional data with response that can take only 3 values?, which is tagged with ggplot2 and wasn't closed? If you look at the thread, you will see the question reads,
I fail to think of a good way to visualize these data. I would like to visualize the space formed by the explanatory variables a,b,c,e,f and see which combinations is causing the the y variable to take one value or another.
That is a question about how to visualize data;
ggplot2 is simply the OP's preferred software. But the OP may not get an answer to that part, and it is part of the social contract here that that is OK. (In fact, neither of the two answers include
ggplot2 code; the one that has plots were made with
JMP.) This example provides another way to think about this issue:
- If a question could be well answered using other software, it is probably on topic here.
- If the answer doesn't matter, but only the code demonstrating the plot does, and it must use the same software, then the question is about the software, not the plot or the data. It is off topic on CV, but may well be on topic elsewhere (like SO).
As a technical detail, almost certainly the close votes were applied from the review queue. The views of the thread in the review queue do not count towards the views enumerated on the thread.
