Using Sho Visualization from F# interactive

Question

Hi Everyone,

Please could someone post a little example of producing a plot from within F# interactive. I've have Yin's example of using the array library from within F# working but I just can't seem to get a plot to work. 

Also, I'd just like to add my support for Sho. Like many here I'm excited to see Sho (and technical computing in general) coming out of Microsoft. I am a long time user of Matlab (for quant finance) but I would really love to leave it behind for a modern language. I like python and I love F# and for me its the interactive visualisation part that still needs some work.

I've tried various 3rd party libraries and some are ok but I'd really like to see a single nice complete and consistent set of viz functions. Sho looks like its going that way. More please!

many thanks,

Paul.

Hi Paul,

 

Here is the code snippet you need:

 

 

// Reference Sho runtime
#r "MathFunc.dll"
#r "MatrixInterf.dll"
#r "ShoArray.dll"
#r "ShoViz.dll"
#r "PythonExt.dll"

// Open Sho namespaces 
open ShoNS.Array
open ShoNS.Visualization
open ShoNS.MathFunc  

 

 

 

// s is an sho array 

// Draw line chart with circles for each value

ShoPlotHelper.Plot(s, "ro-")


// Draw bar chart

ShoPlotHelper.Bar(s)

 

The visualization in Sho is a C# wrapper to Microsoft Chart Controls.

I would also like to recommend you two other F# wrappers to Microsoft Chart Controls:
