Hi.

I have a series of data that I am plotting as either a column chart of Line Chart depending on user preference. If it is a ColumnChart I have to set the SwapRowsAndColumns but other than that the data displays fine.

Based on user input I want to be able to hide a series so when the user picks the series to be hidden I am finding the series within ultraChart.Series and then setting Visible on that series to be False. I then InvalidateAllLayers and call refresh on the chart. When I am using the LineChart this works as expected but when I am viewing the ColumnChart nothing happens. I am assuming that I am missing something simple but I cant see from teh docs.

Do I need to do something else when using a ColumnChart? I cannot use ultrachart.Data.IncludeColumn() because ultrachart.Data is not set because I am using a Series Collection.

Code Below to set visibel. Works fine with Line Chart but not with Column.

foreach (NumericSeries n in ultraChart1.Series)

{

n.Visible = streamDisplay[n.Label] ?

true : false;

}

ultraChart1.InvalidateLayers();

ultraChart1.Refresh();

Thks
