How do I remove and add extra graphs to a skin?

[Ken Booth]

Hi,

I've been able to edit the current.inc and hilo.inc to display tables of the values that interest me, but when I edit skins.conf things just don't go the way I want.

If I comment out

        [[[daywind]]]
            [[[[windSpeed]]]]
            [[[[windGust]]]]

I still get a windSpeed/WindGust graph.

If I add an extra [[[daytemp]]] for more sensors, I get

weewx[24667]: reportengine: Failed to read skin configuration file /etc/weewx/skins/Seasons/skin.conf for report 'SeasonsReport': Duplicate section name at line 267

If I add a new name such as

        [[[daytemp1]]]
            [[[[extraTemp11]]]]
then I don't get an extra graph.

So far I have been able to get temperature graphs by replacing values in existing graphs

##        [[[daytempfeel]]]
##            [[[[windchill]]]]
##            [[[[heatindex]]]]

        [[[daytempfeel]]]
            [[[[extraTemp12]]]]
            [[[[extraTemp8]]]]
            [[[[extraTemp9]]]]
            [[[[extraTemp11]]]]
            [[[[extraTemp7]]]]

So obviously editing skins.conf on its own is insufficient. How do I remove the rainfall and wind graphs, and get more humidity graphs. Which file defines what to generate, and how?

Hi,

I assume you are wanting to add more/change plots on the Seasons main page. If so there are a few moving parts to understand and adjust.

The [ImageGenerator] stanza of skin.conf will control what plots WeeWX will generate and save as image files. Refer to The image generator in the Customization Guide in the first instance. There are a few rules when setting up the [ImageGenerator], stanza, the one that you have fallen foul of is that in a given stanza you cannot have a duplicate entry. So

[[dayplots]]
    [[[daytemp]]]
        [[[[outTemp]]]]
    [[[daytemp]]]
        [[[[extraTemp1]]]]

will give the duplicate section name error you saw but

[[dayplots]]
    [[[daytemp]]]
        [[[[outTemp]]]]
    [[[daytemp1]]]
        [[[[extraTemp1]]]]

will be fine. The latter will result in two image files being created; daytemp.png and daytemp1.png showing plots of outTemp and extraTemp1 respectively. You should be able to see these files on you WeeWX server.

All the [ImageGenerator] stanza does is cause your plot image files to be generated, it has no direct control over whether an image is displayed on your web page (other than if the image file is not generated then it cannot be displayed of course). In the previous Standard skin this was simply a case of editing skins/Standard/index.html.tmpl and either editing the existing or adding new html img tags in the appropriate location. Similar changes are needed to week.html.tmpl, month.html.tmpl etc if you wish to change the plots on the week, month etc pages. The new Seasons skin is somewhat more modular though the same html img tags are used. You need to edit skins/Seasons/index.html.tmpl and make the necessary changes to the html img tags. Note that in the case of the Seasons skin all the current, week, month etc img tags are in index.html.tmpl, not spread across multiple files. So if you want to display the image file daytemp1.png you might make a change like (untested):

  <div id="history_day" class="plot_container">
    <img src="daybarometer.png" alt="$obs.label.barometer"/>
    <img src="daytempdew.png" alt="$obs.label.outTemp" />
    <img src="daytemp1.png" alt="$obs.label.extraTemp1" />
    <img src="daytempfeel.png" alt="$obs.label.feel" />
    <img src="dayhum.png" alt="$obs.label.outHumidity" />

To make changes to the week, month etc plots you need to edit the img tags under the applicable <div id="history_xxxx" class="plot_container">. Once you have made your changes save index.html.tmpl and provided your image files have been generated your web page should display the changed plots after the next report cycle (you may need to refresh the page).

To remove plots from you page you simply delete the corresponding html image tags from index.html.tmpl. That will cause index.html to stop displaying them but the image generator will continue to generate the image file each report cycle. To stop their generation either delete or comment out the respective stanza for that plot under [ImageGenerator] in skin.conf.
