Performance-Visualizer-API-Template

Don't know XAML at all, so what exactly do I need to change in the XAML User Control Manifest?

CODE:

<UserControl x:Class="PerformanceVisualizers.UserControl1"
             xmlns="<a href="http://schemas.microsoft.com/winfx/2006/xaml/presentation" target="_blank">http://schemas.microsoft.com/winfx/2006/xaml/presentation</a>"
             xmlns:x="<a href="http://schemas.microsoft.com/winfx/2006/xaml" target="_blank">http://schemas.microsoft.com/winfx/2006/xaml</a>"
             xmlns:mc="<a href="http://schemas.openxmlformats.org/markup-compatibility/2006" target="_blank">http://schemas.openxmlformats.org/markup-compatibility/2006</a>" 
             xmlns:d="<a href="http://schemas.microsoft.com/expression/blend/2008" target="_blank">http://schemas.microsoft.com/expression/blend/2008</a>" 
             xmlns:local="clr-namespace:PerformanceVisualizers"
             xmlns:
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid>

    </Grid>
</UserControl>

It would be really helpful if a sample code would be available at https://www.wealth-lab.com/Support/ExtensionApi/PerformanceVisualizer. The "meager documentation" eats up hours of effort and causes unnecessary inquiries in the discussion board.

Thansk!

Would something like this do the job?

CODE:
<uc:VisualizerBase
    x:Class="PerformanceVisualizers.UserControl1"
    xmlns="http ://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http ://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http ://schemas.openxmlformats.org/markup-compatibility/2006" 
    xmlns:d="http ://schemas.microsoft.com/expression/blend/2008" 
    xmlns:uc="clr-namespace:WealthLab.WPF;assembly=WealthLab.WPF"
    mc:Ignorable="d" 
    d:DesignHeight="450" d:DesignWidth="800">
<Grid>
</Grid>
</uc:VisualizerBase>

Remove the space between "http" and "://..." - I inserted it to work around the website's syntax highlighter kicking in even in code blocks.

Thanks, that has worked...

Now to my actual problem: How do I get the GetPositionsAllSymbols() function in the Populate() method, so that I can generate and aggregate the list for the line chart for the CreateLineSeries() method?

CODE:

using System.Windows.Media;
using WealthLab.WPF;
using WealthLab.Backtest;
using WealthLab.Core;
using Steema.TeeChart.WPF;

namespace PerformanceVisualizers
{
    public partial class OverlappingPositions : VisualizerBase
    {
        public new IStrategyHost ParentStrategyWindow;
        public new Backtester Backtester;
        public new Backtester BacktesterBenchmark;

        public OverlappingPositions()
        {
            InitializeComponent();
        }

        public override void Populate(Backtester backtester, Backtester backtesterBenchmark)
        {
        }

        public override void Initialize()
        { 
        }

        public void ChartSetup(TChart chart)
        {             
        }

        public System.Windows.Shapes.Line CreateLineSeries(TChart chart, Color color, string title)
        {
            return null;
        }
    }
}

The WL7 API documentation is really very thin. Under Quantacula, Glitch allways published a sample code snippet....

WealthScript methods do not operate inside Visualizers. Backtester backtester has the Positions property you're looking for.

I guess I must be blind, at least I can't find what I am looking for...



Why not just publish a code example showing how the backtester information interacts with the charting functions? I can imagine that questioning and time wasting immediately stops ;-)

On top of your screenshot...

CODE:
public PositionList Positions
public PositionList OpenPositions

I hear you, the API Extension documentation could use some fleshing out. We have a large backlog of feature requests however, so it's just a matter of prioritizing. Also, by answering questions here we're building up our online knowledge base so we can point future questions here as they come up.

The Backtester class (https://www.wealth-lab.com/Support/ApiReference/Backtester) is documented, along with the Positions property therein, and we'll expand and improve the docs once the backlog goes down some.

Glitch,
Unlike the Quantacula forum, in the new WL7 forum you have to fight for every straw, which makes you defenesive over time, which again can't be the goal of a community sharing ideas among each other. Anyway, I'll be patient in that case, since extensions are obviously not an absolute priority.

Just putting this item to the feature request list.
