View Full Version : Graphing Software
October 2nd, 2012, 10:50 PM
Is there graphing software available that would allow me to graph the little empty circles (or some other recognizable symbolism) at points where the function is discontinuous? See the picture for what I mean.

You could do that in R (http://cran.r-project.org/). It's a very powerful statistical analysis software, with a particular strength in making graphs. I know people in the past to have made very powerful and complicated graphs using this software.
It's a bit of a steep learning curve though! You can use the following three web pages to help get you started if you like though
To install R, search synaptic (or the Ubuntu Software Centre actually) for r-base and install that. To run R, simply (!) open a terminal and type
That took me ages to work out when I first started using R!
Post back here (or start a new thread) if you need further help.
Oh -- and since Googling for 'R' is a pain in the Rs, you might like to try using the r-seek (http://www.rseek.org/) website instead.

If the OP would like to program R from a nice GUI, the open-source project RStudio from www.rstudio.org provides a deb binary package for Ubuntu, it works like a charm once you install R from Ubuntu repos.

I used to use Rcmdr, but Rstudio looks nice too!

Here are some examples...
Interactive Pie Charts (http://bl.ocks.org/2212156) (Complexity = Simple)
Interactive Bar Charts (http://bl.ocks.org/2141479) (Complexity = Simple)
Interactive Radial Browser (http://bl.ocks.org/3169420) (Complexity = High)
Interactive Graph (http://bl.ocks.org/2879486) (Complexity = Moderate)
You can find tons more examples, like the graph your trying to build at D3js.org (http://d3js.org/).
I hope this helps and you find it useful because this library was VERY useful for me.
