Data Probe

John_Powell_JMP

A data probe would be a way to drop an annotation or marker at a point on a contour plot (or maybe any graph) and JMP would display the interpolated data (z value and/or other column data) at that point. There could be an option to always display the data value(s) (like a marker label) or only display the value when hovering over the point - like a hover label that could be pinned.

An alternative (or additional) implementation would be an enhancement to the cross hair tool that would display interpolated data in addition to the x and y coordinates. 

This idea was inspired by the following discussion on the JMP User Community:

https://community.jmp.com/t5/Discussions/Finding-values-on-contour-plot/m-p/638494/emcs_t/S2h8ZW1haWx8ZGlnZXN0X25vdGlmaWNhdGlvbnxMSUhFNUVCWlM3UERVN3wtMXxPVEhFUlN8aEs#M83635

Note that users can already display data points in Contour Plots and hover to get their data, but the data probe would allow the user to discover the interpolated value between data points. For example, what would the interpolated z value be at the green point below?  The color legend only tells us that it's somewhere between 0 and 2.

Currently, the Crosshairs tool does a visual zoom, but does not query data.  The hover label infrastructure is based on point-samples, without interpolation.  One general way to consider this wish is for behavior similar to the Profiler to be supported in more graphs.  It would sample the underlying model (in the case of Contour Plot, a linear interpolation in the triangulation) to display the corresponding value.  For Graph Builder smoother curves, it could sample the underlying curve based on the factor/response axes.
