[Clearing a Constant Line]

 Ah ha! 

CC_HIDE is what I was missing.

Thanks very much.

[Clearing a Constant Line]

I don't see a ShowLine property for a Constant Line. 

Perhaps that was introduced in a later version...?

The properties that I do see are:  Axis Label LineColor LineStyle LineWidth Style Value

 

[Clearing a Constant Line]

I have a chart with two constant lines that I create with OpenDataEx COD_CONSTANTS 2I can clear both lines by using ClearData CD_CONSTANTLINESBut what if I want to clear just one line while leaving the other visible?I have tried setting the Value of one line to CHART_HIDDEN, but that makes the line appear at the bottom of the Y axis!  I can set the value to -99999, which does hide the line, but I am uncomfortable with that "solution" since my real data might include -99999.Is there a clean way to clear/hide just one constant line? 

Also...  Another question about a Constant Line:  If I have a chart with both a bar chart and a Constant Line, is it possible to have the Line appear "under" the bars of the bar chart?  Right now, my Line appears "on top" of the bars.  Can the "Z-order" be changed?

 

Thanks in advance for any help on this. 

Yes, I know I should upgrade, but...
