how to draw double lines & double column with due-yAxis in Vizframe

Hi Guys,

I found example on http://veui5infra.dhcp.wdf.sap.corp:8080/demokit/explored.html with only single y-Axis, and combination only for single line& column combination.

However, I would like to create a Vizframe with four measures, two of which are column, and the others are line, and I need it to be due y-Axises.

I refered to the API doc, but found little progress.

Appreciated if any one could give a hint.

Thanks,

Torren
