Is it possible to use ScottPlot with Data Binding on plottables?

I couldn’t find anywhere if it is possible.

I’ve used Syncfusion SfChart before, and it is possible to bind the the chart with it’s series collection, for exemple: <chart:SfChart x:Name="SfChart1" Series="{Binding SeriesCollection}" >

Thant would be amazing to do something similar with ScottPlot, so whenever I update a plottable, the chart updates. <WpfPlot Name="wpfPlot1" Plottables={Binding PlottablesCollection} />

Also, if there is any material about using ScottPlot with mvvm pattern, I would appreciate.

The last question about this, you said about declaring xs[] and ys[] in my ViewModel, not in my View.xaml.cs (code behind). In my ViewModel I’m unnable to interact with wpfPlot and it’s Plottable.

You can create WpfPlot in ViewModel:

public class SomeViewModel: INotifyPropertyChange
{
    public WPFPlot plotControl {get;set;} 
    public SomeViewModel()
    {
       plotControl = new WPFPlot();
       plotControl.Width = ... // manual setup control
    }
}

and bind it in you view:

<ContentControl Content={Binding plotControl}>

It’s bad pattern bring control to VM, but it should work.

I checked the GrovingData demo but I couldn’t find it’s source code.

Hey @eduhza, thanks for raising this issue, and @StendProg for your insightful comments along the way.

@StendProg described the state of ScottPlot very well, and I’ll just add a couple comments for additional context.

MVVM pattern is very common in the .NET word (and is used by many .NET charting libraries, especially for WPF) but ScottPlot’s API was designed to mimic that of matplotlib (a very popular charting library for Python) which uses sequential method calls to load data with numerous optional arguments for style customization.

ScottPlot was designed to make it as easy as possible to create plots from console applications (with WinForms and WPF controls provided as lite wrappers to provide interactivity in GUI environments). As @StendProg noted, adapting it to fit MVVM would be pretty difficult to do well. The best way to go, for now, is for the programmer to control data updates and rendering manually.

@eduhza if you have more questions along the way let us know! Similarly, if your tests reveal interesting findings feel free to share them here. I’ll close this issue for now, but thanks again for opening it initially.
