FSharpChart - Wrapping System.Windows.​Forms.DataVisua​lization.Charti​ng

Hi,

I did an extension to FSharpChart to be able to customize the look of the points (so I can use red crosses like Matlab, for example). Here's the code:

type SeriesProperties with
    
    member series.Marker<'T when 'T :> GenericChart>(?Style, ?Color, ?Size, ?BorderColor, ?BorderWidth) =
        fun (ch:'T) -> 
            Style |> Option.iter ch.Series.set_MarkerStyle
            Color |> Option.iter ch.Series.set_MarkerColor
            Size |> Option.iter ch.Series.set_MarkerSize
            BorderColor |> Option.iter ch.Series.set_MarkerBorderColor
            BorderWidth |> Option.iter ch.Series.set_MarkerBorderWidth
            ch

Would you like to incorporate that into FSharpChart?

The indentation was lost. I've put the snippet here: https://gist.github.com/1305917

Let me look at adding a .Marker into the new minor release. Nice suggestion.

Add ?BorderColor and ?BorderWidth to WithLegend

Hi. Thanks for the suggestions. There are several With... and StyleHelper calls that do not support all posible properties. I am currently looking to see if there are some obvious ones that should be added. I will try and add then soon and issue a new minor release.

Add parameters Title, TitleAlignment, TitleFont and TitleForeColor to WithArea.AxisX and WithArea.AxisY
I've updated https://gist.github.com/1305917 to include this

#load "FSharpChart.fsx"

I got this
FSharpChart.fsx(2934,33): error FS0001: This expression was expected to have type
    int    
but here has type
    int ref    

Are you using version 0.5 of the download. The code in questions seems to be:
    let createCounter() = 
        let count = ref 0
        (fun () -> incr count; !count) 

Yes, I was using version 0.5. It is wired that when I load the script in my home machine (vs2010sp1) I got the error. However when I use it in my office (f# ctp 2011) everything works just fine. I'll do more investigation and let you know if I find something. 
Besides that, I want to know how can I use your lib in a F# project. Apparently I cannot load the FSharpChart.fsx file in my project. 
 
 

To use the code in a project you can either just use the project that one downloads as part of your solution or just compile the code and reference the DLL. In the next release I am hoping to include a DLL that one can use to simplify this process.

When #load "FSharpChart.fsx"
I got this error
