In AChartEngine, how would one create a line plot with scatter residuals -- i.e. using vertical lines to connect the regression line to the scatter plot?
Or, for that matter, is there another Android charting library that can do this?
This is the behavior I'm trying to achieve:
AFAIK that library doesn't give that. For your question, if there's other library: I generally prefer afreechart library, Which, has a full section dedicated to scatter charts (http://afreechart.googlecode.com/svn/doc/screenshot/index.html -> "Scatter charts" heading)
