C# WPF OxyPlot error plot does not exist in namespace

Question

Hi I have a problem configuring oxyplot in WPF. I have found a few solutions but nothing works. I have found out that this is the best http://blog.bartdemeyer.be/2013/03/creating-graphs-in-wpf-using-oxyplot/ but something still wrong and I get this error in XAML file:

the name plot does not exist in the namespace codeplex

MainWindow.xaml FILE:

<Window x:Class="OxyPlotDemo.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:OxyPlotDemo"
     xmlns:oxy="http://oxyplot.codeplex.com"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">

<Grid>
    <oxy:Plot x:Name="Plot1" Title="A Graph" Model="{Binding PlotModel}" Margin="10" Grid.Row="1">
    </oxy:Plot>
</Grid>

MainWindow.xaml.cs

using System.Windows;
namespace OxyPlotDemo

{

public partial class MainWindow : Window
{

    private ViewModels.MainWindowModel viewModel;
    public MainWindow()
    {

        viewModel = new ViewModels.MainWindowModel();
        DataContext = viewModel;

        InitializeComponent();
    }
}
}

MainWindowModel.cs

using  System.ComponentModel;
using OxyPlot;


namespace OxyPlotDemo.ViewModels
{
    public class MainWindowModel : INotifyPropertyChanged
    {
        private PlotModel plotModel;
        public PlotModel PlotModel
        {
            get { return plotModel; }
            set { plotModel = value; OnPropertyChanged("PlotModel"); }
    }

    public MainWindowModel()
    {
        PlotModel = new PlotModel();
    }

    public event PropertyChangedEventHandler PropertyChanged;

    //[NotifyPropertyChangedInvocator]
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
    }
}
}

Maybe someone has better solution. I just need to display a few charts, that contains a lot of data from sensors, not in real time.

Answer 1

I had the same issue. So what i did was downgrade my "OxyPlot.Wpf" to version 1.0.0. and the example you speak of works fine, without the error "the name plot does not exist in the namespace".

 <oxy:Plot x:Name="Plot1" Title="A Graph" Model="{Binding PlotModel}" Margin="10" Grid.Row="1">
    </oxy:Plot>

<Window x:Class="Universal_trc_csvParser.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Universal_trc_csvParser"
        xmlns:oxy="http://oxyplot.org/wpf"
        mc:Ignorable="d"
        Title="Window1" Height="450" Width="800">

    <Window.DataContext>
        <local:MainViewModel/>
    </Window.DataContext>


    <Grid>
        <oxy:PlotView Model="{Binding MyModel}"/>
    </Grid>
</Window>

public class MainViewModel
    {
    public MainViewModel()
        {
        this.MyModel = new PlotModel { Title = "Example 1" };
        this.MyModel.Series.Add(new FunctionSeries(Math.Cos, 0, 10, 0.1, "cos(x)"));
        }

    public PlotModel MyModel { get; private set; }
    }

This worked for me.

I've had a same issue with OxyPlot lib from NuGet, when migrating from lib version 1.x to 2.1. SO i found, that in version 2.1 Plot class is moved to another library, see releases history at their github page. That worked for me:

xmlns:oxy="http://oxyplot.org/wpf"

xmlns:oxycontrols="http://oxyplot.org/wpf/contrib"

<oxycontrols:Plot .../>
