Hi, I am trying to generate a second y-axis and map two data series to this new axis. I am tried to use the configuration JSON from an existing plot.ly chart as template, but it didn’t work. like this: Layout options { "yaxis": { "title": "Y-axis 1", "zeroline": true, "color": "#4682B4", "showgrid": true, "showline": true }, "yaxis2": { "title": "Y-axis 2", "color": "#FF8C00", "showgrid": true, "showline": true, "zeroline": true, "overlaying": "y", "side": "right" } } Has anybody of you an idea how to solve this issue. I think the gap to configure the diagram is not so big. Thanks and regards, Ingo
