I am playing with an example using the SPCBatchVariableControlChart usercontrol. Is there a way to change the Symbols on the Control Chart programatically? I can not find a property to set that will change the symbol, symbolsize, or fillflag. None of the sample projects do this.

Thanks for any help.

You will find some examples on page 237 of the manual. Here are a few that should let you change all of the attributes you list:

this.PrimaryChart.ProcessVariableData.LineMarkerPlot.SymbolAttributes.PrimaryColor = Color.Yellow;
this.PrimaryChart.ProcessVariableData.LineMarkerPlot.SymbolAttributes.FillColor = Color.Yellow;
this.PrimaryChart.ProcessVariableData.LineMarkerPlot.SymbolAttributes.SymbolSize = 18;

this.PrimaryChart.ProcessVariableData.LineMarkerPlot.SymbolAttributes.FillFlag = true;
this.PrimaryChart.ProcessVariableData.LineMarkerPlot.LineAttributes.PrimaryColor = Color.Blue;
this.PrimaryChart.ProcessVariableData.LineMarkerPlot.LineMarkerSymbol = ChartObj.SQUARE;

The symbol attributes apply to every point of the plot, with only the symbol color allowed to change in response to an alarm condition.

Thank you, that did it. I didn't see any of the properties I was searching for on that page, but you got me going in the right direction now.
