Live Debug Data Plotting in F#

ILNumerics Array Visualizer is an interactive, graphical debug tool for Visual Studio. During your debug session it connects to the Visual Studio debug engine and allows immediate insight into the data of your F# program. Arbitrary array data are plotted in various, interactive chart styles: as 1D and 2D line plots, scatter plots, bar plots, as 3D surface plots, and images. Easily describe the data via arbitrary expressions. Export data in a large number of external formats, including charts, HDF5 and Microsoft Excel. Follow your data with each debug step to quickly find bugs in the algorithm.

Visualizing Debug Data - 3 Simple Steps

1. When halted in your Visual Studio debug session go to the Visual Studio View menu:    

VIEW -> Other Windows -> ILNumerics Array Visualizer

2. Enter the name of an array variable from your current debug scope into the expression text area of the Array Visualizer.

3. (Optional) Choose a plotting type from the list of available 2D and 3D plots.

4. (Optional) Apply further configurations to the plot.

Plotting Array Expressions in F#

The capabilities of the Array Visualizer for F# projects match up with the C# options very closely. Please consult the C# Array Visualizer tutorial in order to learn all details.
