Waterfall : add % on top of data label

Hello everyone

I have done my waterfall graph, with datalabel (variation in mEUR). On top, for each variation, I need to add variation in %. In the join excel, for A as axample, I have already datalabel "-4,5", I need to add "-17,9%" as information.

I tried to add a second serie, with the same axis, but it's not working

I need something automatic as I have several similar graphe to do.

thanks for your support !

Modification of the new chart types, waterfall/sunburst/treemap etc, is very limited.

You would need to build the chart in the old way and then you could add extra series to displayed linked data labels.
See Jon Peltier's site for more information on waterfall charts and how to manually construct them.
