Horizontal orientation for legend

Hi,

Is it possible to set legend item orientation to horizontal? Normally they all stack vertically.

Thanks,

Hi Charith,

Unfortunately, there aren’t any ways to do this except modifying control’s template. As a workaround, you could use VisualTreeHelper to get ItemsControl in code and change Orientation of used Panel, or replace it by another panel. Something like the following should help:

            var itemsControl = legendControl.Template.FindName("PART_LegendItems", legendControl) as ItemsControl;
            if (itemsControl != null)
            {
                var factoryPanel = new FrameworkElementFactory(typeof (StackPanel));
                factoryPanel.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);

                itemsControl.ItemsPanel = new ItemsPanelTemplate {VisualTree = factoryPanel};
            }

I logged your request and we will try to improve SciChartLegend in future.

Best regards,
Yuriy

Just to add my 2p: Funnily enough someone else asked a similar question today on email. I would suggest re-templating as then you can do anything (That's the power of WPF!) There is a forum post on custom templating the Legend Control here. Hope this helps! Andrew

Just an update, we are about to release SciChart v3.1, which will include a few enhancements to the legend. In v3.1, syntax to achieve a horizontal legend will include:

<!-- New to SciChart v3.1! LegendModifier exposes ability to dock a legend inside a chart, change orientation -->
<SciChart:LegendModifier  ShowLegend="True"
          LegendPlacement="Top"
          Orientation="Horizontal" 
          ShowSeriesMarkers="True"
          ShowVisibilityCheckboxes="True" 
          Margin="10" />

<!-- OR -->

<SciChartLegend Orientation="Horizontal"/>
