What data structure does it need?
There are two general data formats when dealing with dataframes and we'll use the terminology "long" and "wide". For reference, read the R Cookbook explanation on the difference between the two. Generally, a long format is one where each row contains all the information for a given record so you can append records one at a time.
name,variable,value John,apples,2 John,oranges,3 Jane,pears,1
A wide format is one that is column dependent
name,apples,oranges,pears John,2,3,0 Jane,0,01
highchARRRts prefers your data to be in long format except for categorical data, like the example above.
To convert from long to wide, use the dcast method in the reshape2 package for R. The R Cookpost post can tell you about all the different parameters you might need to use depending on the complexity of your data.
For everything else, long format is what you'll want, which is great because your data is probably already in long format.
highchARRRts has the following required parameters ...
highchaRRRts(dcasted_df, type, main, xlab, ylab, output, pal)
Then in your console, cd to the directory it just created, default name "chart_output". Then create a simple web server such as``` python -m SimpleHTTPServer ```
Then point your browser to 0.0.0.0:8000
highChaRRRts(dcasted_df, type="line", main="Title of the Chart", xlab="X Label", ylab="Y Label, output="chart_output", pal="RdYlBu")
And a colorful example...
library("devtools") install_github("highChaRRRts", "csvsoundsystem") library("highChaRRRts") # generate example data... group <- paste0("group_", 1:11) var1 <- rnorm(11, mean=100, sd=30) var2 <- rnorm(11, mean=100, sd=30) var3 <- rnorm(11, mean=100, sd=30) var4 <- rnorm(11, mean=100, sd=30) var5 <- rnorm(11, mean=100, sd=30) df <- data.frame(group, var1, var2, var3, var4, var5) highChaRRRts(df, type="column", main="Title of the chart", xlab="X Label", ylab="Y Label", output = "chart_output", pal="Spectral")
