Problem using zoom/pan in series with invisible points
Posted: Wed Aug 05, 2009 5:02 pm
I have an application where I use hidden points as a trick to diplay multiple data traces in a single series on a line plot. Specifically, I have (say) x-axis coords which range from 0 to 10 and 3 different y values for each x value. I know this could be done with 3 separate series, but for various reasons I want it presented as a single series to the end user. So I append all the data pairs in a single array, and put a hidden point between the "sets" to keep the last point in one set from connecting back to the first point in the next set in my line plot. This works OK until I try to pan or zoom my plot, at which point all but the first "set" of points (or so it seems) frequently disappear, so my plot now looks like 1 line instead of 3 lines. Can you replicate this problem? Is this a bug? Is there some workaround I can employ? Thanks so much for any help you can provide!
