The SAR plot extends off the plot area.
If you consider this a bug in addSAR, then it's a bug in all the overlay functions (i.e. all moving averages, Bollinger Bands, ZigZag, etc.). It would be nice if the overlay functions checked and revised the y-axis limits, but it's probably more than a trivial patch.
Using chart_Series(..) it is the same except that the background colour of the plot is changed from white to black.
There is no add_SAR, so I'm not sure how you got (or expected) reasonable results by combining chart_Series with addSAR.
