I am unsure what this means: I need to create a PPT chart using x-axis for
BAR CHARTS and y-axis for multiple Lines

A Bar chart uses the vertical (y) axis) for categories while Column and Line
charts use the horizontal (x) axis.

You can make a Line chart with, say, four data series. Now right click on
any one of the data series on the chart and select the item Chart Type. This
allows you to make one (or more) of the data series into Column Charts.
There is no need to use the combo chart gallery to do this.

Hope this helps; please return if more detail needed
best wishes

I need to create a PPT chart using x-axis for BAR CHARTS and y-axis for
multiple Lines .. I see the custom chart type that allows you to create 1
line using y-axis and bar charts using X .. I need two lines, I also see
the
chart type to do two lines, against different axis ... can't figure out
how
to plot two lines to y-axis .. any ideas ?
