Re: Having problems clearing Design time "random" values when starting real timechart

[User (Legacy)]

Gary, 

 hi, you can try looping through the x and y values, setting them to 

CHART_HIDDEN . This will make the values off the chart, 

and therefore not show up. This method, however, will leave 1 series 

present. 

Alternatively, you can remove the first, (and only upon startup)series, 

by 

performing an OpenDataEx-CloseData sequence specifying one less series, in 

this case, 0. 

hope that helps!

ps. what did you mean by the chart "compressing" itself?
