In a dual axis combination chart add the option to show markers (DOTS) on the bars with no line. Merged

This feature would allow users to show two sets of data for the same sample each with their own scale.   No line is needed since the samples are completey indepent of each other and the trend a line shows really does not exist.  Example:  Mass spec protein expression data results shown as bars for each sample.  Dots on the bars show the level of correspording RNA expression.   RNA expression level (dots) and protein expression level (bars) for each individual sample relate to each other, but no line is needed since each sample is completely independent of the other - therfore no trend = no line needed.   This can be done in Tableau and I have attached an example screenshot compared to spotfire.
