I am following the MultiPaneStockChart example. I want to sync multiple chart and I want to sync it on x axis. but it’s not happening although zoom and pinch is working.
Can anyone point me what am I missing?

Hello!

Is there way to create surfaces in different threads (on the same WPF Window) and then synchronize them via groups – methods SciChartGroup.SetVerticalChartGroup() and MouseManager.SetMouseEventGroup() ? Now i catch threads access error 🙁

Thanks!

Hi,

I’m trying to create Multi-Pane Heatmaps by using your example for multi-pane stock charts. I need to have one colormap per viewmodel and I think this should be bound to one HeatmapColourMap each to display the values of color.
So the ItemSource of SciChartGroup is ChartPaneViewModels which contains x number of Viewmodels where I add HeatMapRenderableSeriesViewModel with dataseries to ObservableCollection. Is this possible? I’m having some trouble displaying the correct colors for the data.

Hi,

I want to style the splitter between panes of the SciCharGroup, like changing its height and color.

By using snoop, I can see that the splitter actually is a Thumb control, and SciChart applies a ControlTemplate on it(maybe I’m wrong).
But I still have no idea how to style it.

I need your help.

Hi,

I’m creating a CustomChartModifier which I am able to hook to a SciStockChart (a template item in a SciChartGroup MVVM) and now I’m having difficulties in adding the BoxAnnotation to the Chart.

This is the code I’m using in my ChartModifier and placing a breakpoint shows me that indeed the code runs through this method, however, I do not see any BoxAnnotation on my chart? I’ve even tried adding the Height and Width properties without any further success. Other CustomModifiers to draw Lines and Ellipses works without problems. Do BoxAnnotations work differently?

I’m looking to have the the user be able to draw a BoxAnnotation on the chart, free hand / dynamically.

SimpleBoxAnnotationModifier.cs

public override void OnModifierMouseDown(ModifierMouseArgs e)
{
        base.OnModifierMouseDown(e);

        var resources = new AnnotationStyles();
        // x:Key="BoxAnnotationStyle" TargetType="s:BoxAnnotation"
        var style = (Style)resources["BoxAnnotationStyle"];

        _annotationCreation = new AnnotationCreationModifier () { AnnotationType = typeof(BoxAnnotation), AnnotationStyle = style };

        this.ModifierSurface.Children.Add(_annotationCreation);
}

AnnotationStyles.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:s="http://schemas.abtsoftware.co.uk/scichart"
                x:Class="ChartModifierBinding.AnnotationStyles">

<Style x:Key="BoxAnnotationStyle" TargetType="s:BoxAnnotation">
    <Setter Property="BorderBrush" Value="#279B27"/>
    <Setter Property="Background" Value="#551964FF"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="IsEditable" Value="True"/>
</Style>

Thanks for any pointers or tips!

Hi,

I’m looking to draw a BoxAnnotation onto a SciChartGroup ItemTemplate SciStockChart where the user will left mouse click, drag to define the size and releases to create the BoxAnnotation.

How should I go about doing this? Should I be looking at CustomModifiers or CustomAnnotations?

Any pointers will be very helpful

Thanks

David

Do you have any examples for printing and screenshots when using a multi-pane chart using a SciChartGroup? Our application uses multi-pane charts and needs to be able to print and create screen captures of these as a single unit.

Hi,

I’ve been finding lots of examples of creating Custom Chart Modifiers however they are not using a SciChartGroup using a DataTemplate and not in a MVVM scenario.

I know MVVM is the preferred structure for WPF solutions, however it does introduces some complexities as well as using DataTemplates of a SciChartGroup, therefore, would someone please be so kind as to point me in the right direction for an example or two so that I can see how this all could work together?

I’m looking at Custom Chart Modifiers by use of a CustomModifier class. As this will give me the most flexibility in terms of what I would like to do in the future and I would also like to be able to switch between modifiers, such as Panning, Zooming and drawing annotations onto the chart.

Thanks everyone!

David

P.S. Andrew, if this requires a developer on your side to hash this out for an hour or so, let me know and I’ll be more than happy to pay for it.

I want to implement a requirement to stack several different y-axes on top of a common x-axis that shows time and that all y-axes share. Like the examples “Vertically Stacked Axes”, “Multi-Pane Stock Charts” and “16-channel EEG”.
The one the is the most similar to what I need is the “Vertically stacked axes” but the lines overlap and are not truly separated (possibly implementation detail).
Now two of the examples use a SciChartGroup and several SciChartSurfaces and one uses one SciChartSurface and changes the Y-Axes.
It is a technical Chart and not used for Stocks. Like several temperature (or even mixing with a pressure) lines but in separate charts like “Vertically stacked Axes” and synced to the timeline axis.
But the y-Axes are configurable with different styles and some could be automatically adjusting the range and some not. They will not share the same visual and behavioral styles and must not overlap.

What would be the best way to go or recommended? SciChartGroup or one SciChartSurface. Would it be even possible to implement the behavior on one surface? Any alternatives?

Update
What makes me ask the question?
I had some code in xaml and could style and databind it but the more this gets configurable and unpredictable at design time I end up creating everything in code. I think especially when using multiple SciChartSurfaces. This deprives me of the possibilities of XAML I believe. I still want to have the possibility to style and bind it without coding tons of lines.

Hi,
I have a SciChartGroup with 2 SciChartSurfaces…
It seems the SciChartGroup is adding the surface Title on its own somewhere.
What do I have to do to not display the 2nd surfaces title in white in the top-left corner?
Thanks!

Here is a screenshot of what I’d like to remove:

enter image description here

(I’d attach the project, but the buttons on the ask page aren’t attaching anything – in chrome anyway…)

Here is the codebehind:

using System;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.Windows;
using System.Windows.Input;
using Abt.Controls.SciChart;
namespace nameOn2ndSurface
{
    public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
}
public class datamodel : INotifyPropertyChanged
{
    #region PropertyChanged

    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, e);
    }
    protected void notifyPropertyChanged(string propertyName)
    {
        PropertyChangedEventArgs e = new PropertyChangedEventArgs(propertyName);
        OnPropertyChanged(e);
    }

    #endregion

    ObservableCollection<DataModelGraph> graphs;

    public datamodel()
    {
        graphs = new ObservableCollection<DataModelGraph>();
        graphs.Add(new DataModelGraph() { Title = "graph1" });
        graphs.Add(new DataModelGraph() { Title = "graph2" });
    }
    public ObservableCollection<DataModelGraph> Graphs
    {
        get
        {
            return graphs;
        }
    }
}
public class DataModelGraph : IChildPane, INotifyPropertyChanged
{
    #region PropertyChanged

    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, e);
    }
    protected void notifyPropertyChanged(string propertyName)
    {
        PropertyChangedEventArgs e = new PropertyChangedEventArgs(propertyName);
        OnPropertyChanged(e);
    }

    #endregion

    string title;
    public DataModelGraph()
    {
        title = "graph";
    }
    public string Title
    {
        get
        {
            return title;
        }
        set
        {
            if (title != value)
            {
                title = value;
                notifyPropertyChanged("Title");
            }
        }
    }

    public ICommand ClosePaneCommand { get; set; }
    public void ZoomExtents()
    {
    }
}

}

Here is the xaml:

<Window x:Class="nameOn2ndSurface.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="clr-namespace:nameOn2ndSurface"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <local:datamodel x:Key="data" />
    <Style TargetType="s:SciChartSurface">
        <Setter Property="Foreground" Value="Red"/>
        <Setter Property="ChartTitle" Value="{Binding Title}"/>
    </Style>
</Window.Resources>
<Grid DataContext="{DynamicResource data}">
    <s:SciChartGroup x:Name="group"
                     ItemsSource="{Binding Graphs}"
                     >
        <s:SciChartGroup.ItemTemplate>
            <DataTemplate>
                <s:SciChartSurface />
            </DataTemplate>
        </s:SciChartGroup.ItemTemplate>
    </s:SciChartGroup>
</Grid>

Does anyone know why I would use a SciChartGroup instead of a simple ItemsControl? I tried to use an ItemsControl to show a vertical stack of charts, but I’m getting some weird internal exceptions in SciChart. I’m wondering if the SciChartGroup is a workaround for that?

I need normal (not categorical) x-axes and hence need the SciChartSurface rather than SciStockChart but SciChartSurface does not seem to have the property “IsXAxisVisible” and a number rather vital properties. How can I create a multi pane chart group where I can use SciChartSurface and still retain the ability of, for example, a shared x-Axis?

Thanks

How do you enumerate child charts on a chart group?

My purpose is to try to call ZoomExtents() for each chart in a group after I an event is triggered from the ViewModel which reflects on code-behind of the Window.

Thanks.

Hi Guys

I am using an ItemsControl to display a collection of SciStockCharts. I want to be able to use a single SciChartOverview (not part of the Item Template) to set the visible range on all of the charts displayed in the ItemsControl. Is this possible and if so how would I go about achieving it.

Thanks in advance
Regards
Ian Carson
