I need to produce a combination line/stacked bar graph that has two y axes (one for the lines and one for the stacked bars) and MULTIPLE stacked bars per label. (For example, let's say the labels are month names - for each month, I need to see a stacked bar showing the sale of products A and B in 2005 AND a stacked bar showing the sale of the same products in 2006 for comparison.) I can't figure out how to specify the data series for each of the multiple stacked bars... Is this even possible with FusionCharts? Thank you for your help!
