Control attributes of each individual point in one plot

[lockingnut]

Can I do it?  I create a spiral plot of about 490 points.  At each data point I check something, if good I want a green point along the spiral. If bad I'd like a red point.  So far, changing any attribute at any point in a plot changes them all, not just the one. I've tried having 2 different plots, one for the good condition and the other the bad. When overlapped their all the same.

anyone got an idea?

Having two plots, one for good, one for bad, is the easiest way to go. If good and bad overlap, you need to make a decision what to show in the foreground. This is independent on how you generate the graph. Maybe you can use different point style for the two plots , e.g. empty circles and X-es. 

Of course for full flexibility, you could built it all with a picture indicator, but that would require a bit more work.

Thanks.    Right after I posted I found a message saying the same thing,  tried and it works.  Once I knew what to do it didn't take long at all,  about 3 minutes.  I blew all day yesterday fighting it.

Again,

Thanks!!!!

Don,

With two plots change the values of the points you do not want displayed to NaN. The NaN points do not display. I am not sure how LV draws lines between the other points so this might take some experimentation.

Well  it works great, does just what I need it to do. I've included the code, the program's preliminary. Now I'll add the real code that decides when to change point color & style.
