问题 I would like to add some extra values to the standard Highcharts tooltip via rCharts. Example code: require(rCharts) df <- data.frame(x = c(1:5), y = c(5:1), z = c("A", "B", "C", "D", "E"), name = c("K", "L", "M", "N", "O")) h1 <- hPlot(x = "x", y = "y", data = df, type = "scatter", group = "z") This generates a tooltip with the x and y values. And the series name z as title. Now I also want the to add the name values to the tooltip. However I have no idea how this is done. 回答1: After several

问题 I'm trying to use display categorical levels in the x-axis of my line chart.

I could first create a variable that puts time on a linear scale, e.g. mydata$time_linear <- 1:3 then try to plot library(rCharts) p <- nPlot(value ~ time_linear, data = mydata, type = "lineChart") p$chart(useInteractiveGuideline = TRUE) p but I

问题 I am having a little trouble to draw a horizontal line by using rcharts (highcharts) on a plot. I would like to use the plotLines from highcharts library to do this. Below is my code: a$yAxis(title='my_Yaxis name', plotLines=list(color='red', value=10, width=2)) Without the plotLines, my chart display with no problem. Once i added in the plotLines, it is not working. I am not sure if rcharts support plotLines in highcharts? Appreciate if any experts here can give advice. Thanks! 回答1: Hello

问题 Is there any way to reorder the factor as such Red,Black,Brown,Blond require(rCharts) hair_eye_male <- subset(as.data.frame(HairEyeColor), Sex == "Male") n2 <- nPlot(Freq ~ Hair, group = 'Eye', data = hair_eye_male, type = 'multiBarChart') n2 Thanks 回答1: Reordering factors is an old art. Not to knock it...it's fun In this context I'd revalue the data first. So if you wanted to have red,black,brown,blond appear in that order on the x axis...Add a new variable to your initial dataframe that

问题 when I run the r code in the console, I get the output I expected, but when I run it in rmarkdown I get this result: The complete rmarkdown minimum example looks like this: --- title: "Untitled" author: "sda" output: html_document --- ```{r} library(dplyr) library(tidyr) library(rCharts) library(data.table) ``` ```{r results = 'asis', comment = F, message = F, tidy = F, echo=F, cache=F} myData <- data.table(XAxis = rep(seq(0,length.out = 3),each = 2), Value = c(0.6,0.8,0.4,0.55,0.87,0.42),

问题 I have a simple shiny application (consisting of two files, server.r and ui.r) which uses the rCharts package with Highcharts.

问题 I would like to add several vertical lines indicating particular events in a line chart created with nPlot. Any suggestions? library(reshape2) library(ggplot2) library(rCharts) ecm <- reshape2::melt(economics[,c('date', 'uempmed', 'psavert')], id = 'date') p7 <- nPlot(value ~ date, group = 'variable', data = ecm, type = 'lineWithFocusChart') Final goal: add vertical lines with labels at 'date' = '1967-11-30', '2001-11-30', '1968-01-31', etc. 回答1: Ok, so this should answer the question.
