Bar graph with multiple data sources

[jszit...@gmail.com]

I have two rain gauges and I am trying to show them in the same bar graph.  They both plot, but the plot points (bars) are stacked on each other.  This works when one gauge has a higher value than the other, but not vice-versa.  Unfortunately all of the multiple plot examples in the customization guide are for actual plot lines.  Is there a way to plot the bars next to each other, or maybe control the width?  My current code in skin.conf is:

        [[[dayrain]]]
            yscale = None, None, 0.02
            plot_type = bar
            [[[[rain]]]]
                aggregate_type = sum
                aggregate_interval = 3600
                label = Rain (hourly total)
            [[[[RSrain]]]]
                aggregate_type = sum
                aggregate_interval = 3600
                data_type = rain
                data_binding = RSt_binding
                label = RS

Thanks,

Jonathan

Unfortunately, no, the plotting engine cannot do this. A line is the best we can do.

The Phenology extension to WeeWX comes equipped with an alternate image
generator that does transparency. Bars would overlay one another, but
you could color them so that they show through one another ... I think.
