Right click one data series on the chart and select Format Data Series
Depending on what version of Excel you are using there will be an option
somewhere to use a secondary axis for this data series.
The secondary axis will be on the right-hand side of the chart and will
automatically get a suitable (or near suitable) scale.
best wishes
