morris.js from rCharts

Getting started

---

This is a near exact replica of the morris.js getting started tutorial. All credit and attribution should be directed there. See the copyright and license at the end of this page.

---

The original tutorial says, "Add morris.js and its dependencies (jQuery & Raphael) to your page." Fortunately for us, rCharts handles this for us, and slidify can access this rCharts' brilliance through the ext_widgets: {rCharts: "libraries/morris"} line in the header of this markdown. The config.yml in the morris directory performs the magic.

Your first chart

Instead of the <div> and <script> in the original tutorial, we will build this chart all with the R code below. You should notice a lot of similarity.

#if you have not installed slidify, slidifyLibraries, or rCharts
#require(devtools)
#install_github('slidify', 'ramnathv', ref = 'dev')
#install_github('rCharts', 'ramnathv')
#install_github('slidifyLibraries', 'ramnathv', ref = 'dev') # optional

require(rCharts)
#specify the data
data = data.frame(
  c('2008', '2009', '2010', '2011', '2012'),
  c(20,10,5,5,20),
  stringsAsFactors = FALSE
)
colnames(data) <- c("year","value")
#build the plot
m1 <- mPlot(
  x = "year",
  y = "value",
  data = data,
  type = "Line"  
)
m1$set( labels = "value" ) 
m1

What Next?

Check out the rest of the documentation (which we will also eventually replicate using rCharts):

• Line and area charts
• Bar charts
• Donut charts
  

Also, check out Ryan Bates's excellent RailsCast #223 Graphs and Charts (note:requires subscription).

Thanks to:

• Ramnath Vaidyanathan for his incredible slidify, rCharts, and more specifically help with this post
• Olly Smith for his very nice morris.js charting library.
