Hi, would like to plot the overlayed monthly production of my solar inverters for the last years. RRD consolidation is done per month, so I have 12 values per year to overlay.
simply plotting LINE or AREA doesn't do the trick, as for some years the monthly production is higher than the other years and vice versa -> the lines and/or areas cross, for areas the colors add up and in the end it's not readable at all. I currently have 4 years of data, can't imagine to be able to see something if I overlay 10 years ! I think the best way to display such data would be what I found out to be called clustered graph, i.e. for each month the year's columns side by side (see https://support.content.office.net/en-US/media/709339c5-da15-400a-8ca1-21ef1d709fe5.gif for a demo pic of that kind of graph in excel). Everybody knows that kind of representation, but now question is how to draw this with RRDgraph ? I'm not aware of a command to make columns narrower and group graphs side by side.
