Thanks Jeff - that solved the stretching issue for me.
I've created a line chart in Graph Builder, with points marked along it. I want to highlight the points that represent a major change in the y-axis value (see the colored points below)
In JMP9, I could select all of the black points and "hide" them, leaving the line and just the colored points. In JMP10, I get this when I hide the black points:
The line disappears! This is also the case in the overlay plot where the line will only connect visible values. In effect, Hide seems to be doing the same thing as Exclude, and previously they were different.
Another change I've noticed in JMP10 is the way selection affects lines. If I want to box- or lasso-select the four highest points in the graph, it selects the entire series (the whole line, or all of the points in the table.) In JMP9, it would effectively ignore the line and just select those 4 points.
I can pass along a sample table if you can't reproduce this behavior. Thanks again for your help!
