问题
I am developing a Shiny app which I hope to look like the picture below:
However, as I try to achieve this, I am only able to get the following form:
I am looking for how to make the output neatly collected, and would appreciate any help. I have looked at a couple of other similar questions here, viz. this and this, but don't think they answer my question (the first talks about adding a mainPanel, but I am using FludiPage and FluidRows. I had thought the columns and rows would automatically adjust to screen size, and that 12 columns are designed to fit into a screen size, but apparently I am wrong?
Many thanks for the help.

Edit:
Following is a code to generate the CSV file to be fed to this app.
earnPtsRange <- 12000:18000
earnCountRange <- 1000:10000
redemPtsRange <- 10000:20000
redemCountRange <- 10000:20000
churnRange <- 1000:10000
acquisitionRange <- 800:15000

redemCount <- sample(x = redemCountRange, size = 190)
churnCount <- sample(x = churnRange, size = 190)

## merge the generated data
toyData <- data.frame(dateValues = dateValues, earnPts = earnPts, earnCount = earnCount, redemPts = redemPts, redemCount = redemCount, churnCount = churnCount,
acquisCount = acquisCount)
## write the data to a CSV file
write.csv(x = toyData, file = './toyDataset.csv', row.names = FALSE)
Many thanks in advance.
回答1:
I have just pushed what I think is a fix to your issue on my fork of rCharts. It solved my issues with responsiveness and auto-resizing with rCharts. The way you use it is by specifying a width and height parameter in showOutput. Default width is 100% and default height is 400px.
Example call would be showOutput("myGraph", "nvd3", height=555)
You can download from: https://github.com/clecocel/rCharts
And you can install it by using: devtools::install_github("clecocel/rCharts")
