Graphing GW2000 Piezo rain

[Stephen Hocking]

Hi all,

I've obviously missed something here, but I thought adding a stanza of the form

       [[[dayprain]]]
            # Make sure the y-axis increment is at least 0.02 for the rain plot
            yscale = None, None, 0.02
            plot_type = bar
            [[[[p_rain]]]]
                aggregate_type = sum
                aggregate_interval = hour
                label = Piezo Rain (hourly total)

After the similar entry for dayrain in skins/Standard/skin.conf and adding the line

         <img src="dayprain.png"     alt="Piezo rain" />

after the similar entry for dayrain in skins/Standard/index.html.tmpl would be sufficient, but when I restart weewx and look at the result, I get the missing image graphic where I would expect to see the plot. Can anyone point me in  the right direction?

First thing to check is does your archive have a field p_rain? If you want plot the observation p_rain it needs to be saved to archive. Have you done that? wee_database --add-column would do that for you. More detailed coverage on modifying the database schema can be found here in the Customisation Guide.

Hi Gary,

That seems to have worked - thank you very much! Now to find why the Seasons skin isn't plotting a lot of its stuff...

You will find Seasons is quite different to Standard. Seasons was parameterised in v4.6.0 and it now automatically picks up a wide variety of observations in thew view_extended schema. It won't pick up p_rain so you will need to make some changes, but these should be limited to skin.conf, in particular the [DisplayOptions] and [CheetahGenerator] stanza. If you follow the entries that include rain, and add in p_rain you should be pretty close.

Turns out there was an error (which I still haven't quite tracked down) in the skins.conf for Seasons, where a lot of extra sensors that hardly anyone has were listed. This was stopping the images for windspeed, wind direction and quite a few others from being generated. When I moved their stanzas before those of the extraneous sensors, the images were being generated again.

Stephen,

Seasons was recently 'parameterised' and it is designed to handle a lot of commonly used observations, but only report on/generate plots for those observations that are available. If it's giving an error out of the box then that's a bug and we would like to fix it. Can you please give us some details so we can look into it further.
