Dynamically Creating Plots in Skin.config

[Carter Humphreys]

 Fff
Is it possible to dynamically create plots from a weewx skin config? My extension creates variables in a database based on sensors defined in weewx.config, so I want to create the same plots across all sensors.

So what I was hoping to do is make it so that I can define the sensor IDs in the weewx.config, then be able to generate plots for those without having to define the same plot for each sensor.

Any ideas how to do this? Or if it is even possible?

Thanks!

Hi,

[Tom Keffer]

I'm not exactly sure what you're asking for. 

Right now, the image generator requires that there be a quadruple stanza ("[[[[ ... ]]]]") for each plot. For many skins, for example, the Seasons skin, whether it actually gets used depends on whether it is mentioned under [DisplayOptions] and whether it has any data in it. Is that what you're looking for?

Or, do you mean that you want to just start with some observation type, such as "houseVoltage", and from that create a plot, perhaps using a template? In this case, it's a good idea, but the image generator cannot do that.

Sorry, I probably could have explained that better.

I’m trying to go that second route. I’m trying to avoid the repetition of having to define a plot in the generator for each of the defined sensors.

So the ability to do something like:

for sensor in user_config['sensors']:

    [[[ plot_example 1]]]

    [[[ plot_example 2]]]

That way the same plots are generated for each sensor (since they all have the same data). 

I’m guessing the way this would work is to go is just create a json file with the data from the time series tag, and then create the plots in JavaScript.

Perhaps generate skin.conf programmatically ??

That could probably also work. I was just more trying to see if there was a native solution in place already. Thanks for the idea!
