How to generate clickable bigger graph pictures ?

[Stéphane Calonnec]

Hello,
I am using WeeWX 3.6.2 with latest Interceptor driver on my Weathersleuth on my RPi 2 (everything works fine, except the wind gust dir never worked, the values are NULL), with the default skin (but heavily edited), and I'd like to click on a graph to enlarge it (to a new window for instance, no need of lightbox), but I don't know how to do this in WeeWX.

I found an interesting topic about adding some stansa to generate bigger pictures to a specific folder along the "regular" graphs (which is what I look for) but I do not know at all what stansa to add ; I also tried to give a look to some skins doing it but I could not find anything helpful to me. If I really can't, I'll trick using CSS.

May anyone give me some clues to generate bigger files in a specific folder ? :)

Thanks in advance !!!

In weewx.conf I have the following

 

[[StandardReport]]

        # See the customizing guide to change the units, plot types and line

        # colors, modify the fonts, display additional sensor data, and other

        # customizations. Many of those changes can be made here by overriding

        # parameters, or by modifying templates within the skin itself.

        # The StandardReport uses the 'Standard' skin, which contains the

        # images, templates and plots for the report.

        skin = Standard

        [[[Units]]]

            [[[[Groups]]]]

                group_pressure = mbar

    [[BigReport]]

        skin = Standard

        HTML_ROOT = public_html/big

        [[[ImageGenerator]]]

            image_width = 619

            image_height = 413

Then in index.html.tmpl I have the following

                <td class="data">$almanac.moon_phase<br/>($almanac.moon_fullness% full)</td>

              </tr>

            </table>

            #end if

          </div> <!-- end class "celestial_group" -->

        </div> <!-- end id "almanac" -->

        <div id="plots">

<a href="big/daytempdew.png">            <img src="daytempdew.png"   alt="temperatures" /></a>

<a href="big/daytempchill.png">          <img src="daytempchill.png" alt="heatchill" /></a>

<a href="big/dayrain.png">               <img src="dayrain.png"      alt="rain" /></a>

<a href="big/daywind.png">               <img src="daywind.png"      alt="wind" /></a>

<a href="big/daybarometer.png">          <img src="daybarometer.png" alt="barometer"/></a>

<a href="big/daywinddir.png">            <img src="daywinddir.png"   alt="Hi Wind" /></a>

<a href="big/dayinside.png">             <img src="dayinside.png"    alt="Inside" /></a>

<a href="big/daywindvec.png">            <img src="daywindvec.png"   alt="Wind Vector" /></a>

          #if $day.radiation.has_data

          <img src="dayradiation.png" alt="Radiation" />

          #end if

          #if $day.rxCheckPercent.has_data

<a href="big/dayrx.png">                 <img src="dayrx.png"        alt="day rx percent"/></a>

          #end if

          #if $day.extraTemp1.has_data

          <img src="daypond.png"      alt="Pond Temperatures" />

I think this is EXACTLY what I wanted, thanks very much !!!! It looks so easy, but I really didn't know how to do...I'll test but I'm sure it will work :)
Thank you again ++++++++++++++++

[Stéphane Calonnec]

I just tested your code, it works perfectly, thank you again, this is something I was trying to do since a long time !!

[Dave Webb KB1PVH]

Glad it worked for you.

Dave, was there any particular reason for placing these in weewx.conf (which causes the full report to run twice) versus modifying skin.conf?

I simply added stanzas such as:
        [[[bigdaybarometer]]]

            image_width = 619
            image_height = 413

            [[[[barometer]]]]

Into the skin.conf, and then made similar edits to index.html.tmpl as you did below.

Chris,

To be honest, I'm not sure why I did it that way, LOL. I'm far from a programming ninja.

Chris,

 I got thinking about your comment and I believe when I first started the Big plots it was weewx 2.7.x and you could just enable Big reports and I adjusted the size.  The newer versions of weewx implement it differently, I think.

Seems to be the case. When I saw that this method was creating the entire report twice I figured there had to be another way. :)

[Dave Webb KB1PVH]

It only seems to create it one time here according to the log.

​Skin configuration, including overrides from weewx.conf, have not changed since they were introduced in V1.7.0, now 6+ years ago.​

[Chris Mattingly]

Interesting. At any rate, I'll stick with the additional image generation inside the skin to save that tiny bit of CPU and disk space. ;)

[Stéphane Calonnec]

Very interesting posts :)
It's indeed creating a whole new report into the big folder.
I don't understand the syntax [[[bigdaybarometer]]], does it generate a file bigdaybarometer.png into the root folder ?
I deleted (commented) the weewx.conf edit to test the [[[bigdaybarometer]]] addition to skin.conf,but I don't know where the file drop. Also, my barometer graph is now empty (I have grid and time, but no graph and no title), I think I put the stanza on the wrong place. Here is my latest syslog (after 2 init.d reload and stop/start of course):

Dec 19 14:10:06 raspsc weewx[15359]: cheetahgenerator: Generated 14 files for report StandardReport in 7.22 seconds

Python is so new to me... :p
I'll look for that later :)

[Stéphane Calonnec]

Back ! The picture is now generated, and i put the stanza in the wrong place, so it could not work properly. Now everything looks to work fine, and I understand now how syntax works... :)
Thanks for everything, I think this will be easier to manage for my Raspberry !!

I'll try to add a vertical line to midnight in day pictures (to show separate days) and change some colors (but I'm used to HEX formatted colors, like #000000 but when I add the "#" it crashes as it takes it as a comment lol).
