At the moment the scatter plot does not offer any visual highlight for selection events (that is, the selection is registered, but the selected point is not visually differentiated from the others, see https://groups.google.com/d/topic/google-visualization-api/jwLMkhwKP6c/discussion), so plain setSelection won't work for you. Other team members might detail whether changes are happening in this area or not, because I'm not fully up-to-date on this.
In the meanwhile, since the scatterplot uses a separate color for each data serie (each datatable column) an alternative solution might be the following: - when a point is selected (via setSelection or by user click), identify the correspondent datatable row and move the cell containing the point value to a separate column (this will trigger a color change) and redraw the visualization. - when another point is selected, revert the previous change and apply the previous step. I haven't explicitly coded this, but I think it should work, although it's a non trivial amount of helper code to write. -- R.
