Want to add more than 1 graph to a legend.

[anuja-mandlecha]

I am creating a realtime dashboard using rickshaw and in it I want to add more than 1 graph to a legend so that on clicking on the legend all the graphs should change accordingly. But I cannot find any such feature as on.. I tried adding a new graph variable into legend.js and toggle.js and changing the series and line variables accordingly but it didnt work.. By doing this only the last graph is getting affected whereas others remain static. Can anyone please help me?
