During his June 5, 2018 Explorers Series presentation, Kaiser Fung pointed out that only the final plotted symbol is visible when the same value occurs multiple times, resulting in overplotting. It would be helpful to have a standard feature that would allow one to examine the overploltted points to get a feel for what lies beneath the visible plot symbol. Two options come to mind:
(1) Think Map software uses a branching tree to graphically display data values. You can grab individual data points or a node and move it out into a clear area of the chart to examine it more closely. When you relase the node or point, it springs back into place and you can continue to explore.
(2) Clicking on a point could pop up a new window that lists all overplotted data values, as well as highlighting them in the worksheet. A Pareto chart by a stratifying variables would reveal patterns in the mix. Additionally, a time series plot would be great,since the final plotted symbol represents the last data value in worksheet order, so time may be an contributing factor.
