如何在曲线R中固定条的宽度

Question

Plotly is one of the most useful plotting packages in R, but I am facing a very basic issue with it.

When I am drawing a barplot , it looks ok in a small screen, but as soon as I resize the window , it covers the whole window, making it ugly.

As my requirement is dynamic , number of bars on the plot changes, but I want to keep the bar width look decent.

But when it gets resized

the code which I am using to plot the barplot is simple and I hope need not be explained . The width option doesnt make any impact on the graph.

Am I missing anything?

 ds <- as.data.frame(matrix(c('some_name',2300),nrow = 1,ncol=2))
colnames(ds) <- c('name','value')

plot_ly(ds,x=name,y=value,type='bar') %>% layout(width = 0.1)

Answer 1

ploty中没有名为bar size的选项，但您可以在布局中使用bargap选项。

Answer 2

Yes, you need to set the autosize=F . So correctly it should be :

plot_ly(ds,x=name,y=value,type='bar') %>% layout(width = 100, autosize=F)

Another option is to set width and height in the plotlyOutput (keeping the autosize=T ): plotlyOutput("plot", height="700px", width="200px")))

Answer 3

I could not find the answer either, but I found an alternative solution, which is to use dot plot, instead of bar chart.
