Dragable Point Data on Scatter Plot

Thanks David!

Hey Niklas, I'm sorry I didn't respond sooner.  The use cases I'm seeing for this are Rate Transient Analysis, Neutron Density Clean/Shale Point picking for scatter plots, Picking inflection points in a histogram bar chart.  I think technically there are actually 2 feature requests tied to this. 

1. The ability to plot a Reference Point in addition to "Lines & Curves" in scatter plots (perhaps map chart)
   • that feature would very helpful for label placement for chart visualization, which are often times in the most intuitive place a plot.
   • This can be accomplished hackishly with 2 intersecting lines, or a crazy if statement
     • If(x>=${ShaleNPHI}-0.01 and x<=${ShaleNPHI}+0.01,${ShaleRHOB}, null)
2. The ability to drag a Line(horizontal or vertical) or Reference Point (feature 1 above) interactively in a visualization if it is activated and tied to a Document Property (or properties in the case of a data point) changing the underlying document properties.

The ability to plot Reference Points by picking document properties for X, Y, and the ability to change a document property by dragging it around a visualization, would be transformational, making Spotfire a more intuitive interpretation tool.

Hi David, thanks for sharing your ideas. I think I understand the request, but it would be interesting if you could elaborate a bit on the use-cases you are thinking of for this idea?
