Making symbols appear in the chart legend

Can you insert a symbol into the legend on a chart?

I have attached a sheet and would like the countries flag to appear in the legend along side its name

You can but it maybe easier to build your own legend with shapes.

In the attached example I added 2 series, changed to column chart type and then used the flags as picture fill.

The right hand example adds another series which has the legend key text enlarged to increase the size of the flags. I also sized the legend to align the flags and lines.
