Hi,

I am working with a large data set, and I am using Graph Builder to display the results. My problem is that if I use lines on Graph Builder to display the data, there is some smoothing taking place, and the shape of the line does not accurately represent the data. If I use dots on Graph Builder, the data is accurate, but it is a little hard to see. I can use the Overlay platform to achieve lines that accurately display the fine shape of the data, but the Overlay platform does not filter data as cleanly as in Graph Builder.

Does anyone have any suggestions about how I can use Graph Builder to accurately display the fine shape of the data? I am using JMP11.

Thanks!

Solution

In JMP 12 the Graph Builder lines look "right" out of the box; it plots slower but without the automatic interpolation that happens in JMP 11 for large data sets.

If you reduce the number of rows (e.g. by truncating or summarizing) the stepwise line pattern will be correctly displayed in JMP 11 too. I tried to reduce the number of rows to 100000 and then it looked OK.
