Hi, I tried to use ggobi to display my data, and use the brush to select some data and calculate a particular value for the data points in the brush, then some points need to change the colour according to the particular values. Does anyone knows the way that I can change the colour of some of the points without redraw my current plot and reset the colour to default when the brush moves on?
