I need to display line chart for very long vector ( about 200.000 points ). The time of chart loading is very long ( The 20.000 points chart loading gets about 20sec ). Each action required redrawing in the chart area, like zoom or series enable/disable, causes to refresh for long time too. Could you let me recommendation how I can improve a chart performance? Thanks, Elina

I try to realise the zoom functionality in my application used ChartFX. Actualy I need something (little bit) more complicated than Magnifier. First of all, I have number of different charts in my application, part of them have one panel with different series, and one is multipanel chart. If on the one panel chart I can use ZoomStyle = ZoomStyle.Strip (or Auto) mode and it works satisfactory, but on the multipanel char If I'll set the next mode: After a first selection I'll get the ArgumentException: An item with the same key has already been added. If I use Zoom.Style = ZoomStyle.Scroll, I could select only once, after then I get the scroll bars and can't select more. My customer want to make sequence of nested zooms and option to zoom out. How could I make sequenced selection and get the min and max points of the selected area after each selection ( I need zoom only by axes X has date/time format ) Thanks WpfApplication1.zip

I'm again. I've gotten the tooltips for LegendBox iems in this way. What do you think, Is it right way? <cfx:LegendBox.ContainerStyle> <Style TargetType="{x:Type ItemsControl}"> <Style.Setters> <Setter Property="ItemContainerStyle"> <Setter.Value> <Style> <Style.Triggers> <Trigger Property="Control.IsMouseOver" Value="True"> <Setter Property="Control.ToolTip" Value="{Binding Content}"/> </Trigger> </Style.Triggers> </Style> </Setter.Value> </Setter> </Style.Setters> </Style> </cfx:LegendBox.ContainerStyle>

Thanks. That's as exactly as I need! Now, I need to attach a Tooltips to LegendBox items. I use the vertical Legend on the right side with fixed width, and the long items aren't visible fully. I can add ToolTip to all the LegendBox, but I don't know how to add tooltip to each item and bind the Item Content as the tooltip text.

Any ideas about my issue?

Hi, JuanC I use the multiply panes chart and my LegendBox contains two groups for separate the series from different panes. I want to separate the Legend to two different boxes ( if it's possible, of course ) and align each of them to appropriate pane. What about the Q2: Tooltips for Legend Items? Thanks P.S. How can I add pictures from my computer and not from URL?

I use the version 8.0.3581.26941 I have two Q. 1. How do I do 2 different LegendBoxes instead use a grouping in one Legend? 2. I haven't added tooltips for LegendBox Items ( I won't use a scrool bar in the legend box, but tooltip for the long items only). I've tried to add a tooltip definition to DataTemplate\ContentControl like this, but it's not working. What can I do? <DataTemplate x:Key="CheckableLegend"> <DataTemplate.Resources> <cfxConverters:VisibilityToBooleanConverter x:Key="VisibilityToBool"/> </DataTemplate.Resources> <Grid Name="grid"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" SharedSizeGroup="FirstRow" /> <ColumnDefinition Width="*" SharedSizeGroup="FirstRow" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions><CheckBox VerticalAlignment="Center" Background="{Binding Path=Fill}" IsChecked="{Binding Path=Series.Visibility, Converter={StaticResource VisibilityToBool}}" Grid.Column="0" Margin="1,0,1,0"/><cfxControls:MarkerLegendControl Content="{Binding Path=Self}" Grid.Column="1" /> <Border Background="Transparent" Grid.Column="2" VerticalAlignment="Center"><ContentControl IsHitTestVisible="false" ToolTip="{Binding Path=Content}" Content="{Binding Path=Content}" ContentTemplate="{Binding Path=ContentTemplate}"Foreground="{Binding Path=Foreground}" FontFamily="{Binding Path=FontFamily}" FontSize="{Binding Path=FontSize}" FontStyle="{Binding Path=FontStyle}" FontWeight="{Binding Path=FontWeight}"/> </Border> </Grid> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Path=Dimmed}"><DataTrigger.Value>True </DataTrigger.Value> <Setter Property="Opacity" Value="0.25" TargetName="grid" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate>Thanks, Elina
