ToString

THE LEGEND SETS THE WIDTH here, which is why it cannot be left to a host to bolt on afterwards: three series named Sales, Costs and Profit need 31 columns of legend under a chart whose bars occupy 32, and a fourth series would make the legend the wider of the two. The engine lays out both together.no extension
