Questions

Hi,

I’ve got a collection on FastLineRenderableSeries which are set to Visible true/false based for some boolean properties. At the moment I’ve been using IsVisible property and apparently it’s not working very reliably. Most of the time it works without issue. But time to time chart comes to a stage which it does not respect IsVisible property and make all series are Visible. It’s quite difficult to identify reproducible steps and it occurs randomly.

<visuals:SciChartSurface.RenderableSeries>
                                <renderableSeries:FastLineRenderableSeries x:Name="vaSeries" DataSeries="{Binding Path= Series[0], Mode=OneWay}" 
                                                                IsVisible="{Binding ElementName=ChkVa, Path=IsChecked, Mode=OneWay}"
                                                                SeriesColor="{StaticResource VaColor}" Style="{StaticResource SeriesStyleWithPoints}" />
                                <renderableSeries:FastLineRenderableSeries DataSeries="{Binding Series[1], Mode=OneWay}" 
                                                                IsVisible="{Binding ElementName=ChkVb, Path=IsChecked, Mode=OneWay}"
                                                                SeriesColor="{StaticResource VbColor}" Style="{StaticResource SeriesStyleWithPoints}" />
                                <renderableSeries:FastLineRenderableSeries DataSeries="{Binding Series[2], Mode=OneWay}" 
                                                                IsVisible="{Binding ElementName=ChkVc, Path=IsChecked, Mode=OneWay}"
                                                                SeriesColor="{StaticResource VcColor}" Style="{StaticResource SeriesStyleWithPoints}" />
                                <renderableSeries:FastLineRenderableSeries DataSeries="{Binding Series[3], Mode=OneWay}"
                                                                IsVisible="{Binding ElementName=ChkVr, Path=IsChecked, Mode=OneWay}"
                                                                SeriesColor="{StaticResource VrColor}" Style="{StaticResource SeriesStyleWithPoints}" />
                                <renderableSeries:FastLineRenderableSeries DataSeries="{Binding Series[4], Mode=OneWay}"
                                                                IsVisible="{Binding ElementName=ChkVs, Path=IsChecked, Mode=OneWay}"
                                                                SeriesColor="{StaticResource VsColor}" Style="{StaticResource SeriesStyleWithPoints}" />
                                <renderableSeries:FastLineRenderableSeries DataSeries="{Binding Series[5], Mode=OneWay}"
                                                                IsVisible="{Binding ElementName=ChkVt, Path=IsChecked, Mode=OneWay}"
                                                                SeriesColor="{StaticResource VtColor}" Style="{StaticResource SeriesStyleWithPoints}" />
                            </visuals:SciChartSurface.RenderableSeries>

1. Any idea how this could happen?
2. Noticed that there two properties for the purpose of making its visibility ‘IsVisible’ and ‘Visibility’. What is the most reliable property to use for setting Visibility of FastLineRenderable series?

Thanks!
