Hello,
I am trying to make different color for chart legend created by Rcharts in Rshiny. For example: I want to make chart legend font and label font in yellow color text instead of the black color text (because I customized my panel in dark grey. The default black color of the font from Rchart makes any font hard to tell). But I could not find how to do it. Any help will be greatly appreciated!

hair_eye = as.data.frame(HairEyeColor) p2 <- nPlot(Freq ~ Hair, group = 'Eye', data = subset(hair_eye, Sex == "Female"), type = 'multiBarChart' ) p2$chart(color = c('brown', 'blue', '#594c26', 'green')) p2 p2$chart(showLegend=TRUE) p4$chart(labelType="value")

I am trying to reproduce the shiny app as described here
However, when using

choices = sort(unique(dat2m$country))

I get the numbers 1 to 35 as possible choices, NOT the names of the countries (as one would expect).
If I use

choices = c("Belgium","Canada")

it does display these two countries correctly...

I am working on a Windows 7 platform,
using RStudio Version 0.98.1102,
rCharts 0.4.5,
and Shiny 0.11.1

Sorry to bring this up, as it looks like it was fixed in a commit 22 days ago, however the online shiny app still displays numeric country choices for me (screenshot taken 03/06/2015):

I looked at the code, which seemed like it couldn't possibly create numeric choices, so I cloned the files and ran a local version of the app. It's indeed correct:

Might the code have been fixed on github, but not updated on the shiny server?

This didn't really bother me; I just wanted to drop a courtesy note in case you weren't aware!

Am I doing something incorrectly?

Just downloaded the zip, extracted, cd'd to the rChartOECD dir and:

Hi Ramnath:

You are doing great work in this area. Quick question for you - i installed the rCharts package and tried a test plot but 'printChart' sets up the server at port 8100 but the web browser is unable to display anything.

Do I need to install anything else, like the polyCharts library in addition to rCharts, or is it all self-contained and there's something else going on.

Thanks

Hi,

Thanks for providing such a powerful tool. I want to share the rchart with other people, how can I paste the chart into a email? I tried to use the html, but the chart doesn't show up.

Best,
Rita

Hi there,

Awesome package -- I wanted to reproduce the example in Shiny with the code for this example: http://ramnathv.github.io/rChartsShiny/

Running the code in global.R and subsequently storing ui.R and server.R in a folder, I executed runApp and had this error returned:

runApp(".../rchart/")

Listening on port 8100
Error in addResourcePath(LIB$name, LIB$url) : object 'LIB' not found

I've Googled this error but couldn't find a solution. I did not edit any code whatsoever, I simply tried to reproduce the example. Could you help me out with this error?

Thanks!

Quick edit: I'm using R version 2.15.3 (2013-03-01) on OS X

I've got another question --

With the rPlot(), under ui.R I simply have to pass the identifier over to showOutput. Say the identifier is "chart", then I'd pass that to showOutput("chart", "polycharts").

Regarding nvd3Plot(), how would I go about displaying the plot in Shiny? showOutput() didn't work for me.

Thanks!

Alan
