I assume that what you want is one chart data series for two discontinous
worksheet series.

one method to do this is to plot the first series. with the chart active
goto <chart<source data<Series in the values box afer the listing add a
comma and use your curser to select the rest of the data you want to plaot as
part of hat series.

Is this possible ?
