I've been trying to create a horizontal bar 3D bar graph with alternating rows of red and white in the background and blue bars. I've looked into alternate formatting commands and I've come up with what would be a good solution, except where the risers are there extends black and white border lines at each point in the graph where I set a separation. I want to eliminate those but everything I've tried has had no effect on them. I was wondering if any graph experts here either knew of a solution or had an alternate solution for this.

To further see what the issue is, I've written a simulation of this against the car file:

SUM SEATS

WHERE CAR EQ 'AUDI' OR 'BMW' OR 'DATSUN' OR 'JAGUAR' OR 'JENSEN' OR 'TOYOTA'

setAltFmtFrameSeparator(getO1AltFmtFrame(2),2);
setAltFmtFrameSeparator(getO1AltFmtFrame(3),3);
setAltFmtFrameSeparator(getO1AltFmtFrame(4),4);
setAltFmtFrameSeparator(getO1AltFmtFrame(5),5);
setFillColor(getO1AltFmtFrame(0),new Color(255,250,250));
setFillColor(getO1AltFmtFrame(1),new Color(255,0,0));
setFillColor(getO1AltFmtFrame(2),new Color(255,250,250));
setFillColor(getO1AltFmtFrame(3),new Color(255,0,0));
setFillColor(getO1AltFmtFrame(4),new Color(255,250,250));
setFillColor(getO1AltFmtFrame(5),new Color(255,0,0));
setFillColor(getO1Label(),new Color(0 0 255));
setRiserWidth(40);
setFillColor(getFrame(),new Color(255 250 250));
setFillColor(getSeries(0), new Color(0 0 255));
setFillColor(getSeries(1), new Color(0 0 255));
setFillColor(getSeries(2), new Color(0 0 255));
setFillColor(getSeries(3), new Color(0 0 255));
setFillColor(getSeries(4), new Color(0 0 255));
setFillColor(getSeries(5), new Color(0 0 255));
ENDSTYLE
END

Thanks.
