If you mean that you want two series with bars ( columns ), and a series of a line in the same chart, then select all the data to create a column chart with 3 series ( data in columns ). Once the chart has been created, select the "Index" series, and do menu command Format/Series/Axis, and choose secondary axis. Now use the Chart Type drop-down from the Chart toolbar to change the series to be a line chart, and hey presto, you're finished.
