Gauge Type Default

krmidas · **Posted:** Sat Jul 21, 2012 2:32 pm

On the gauge that displays wind chill/heat index/dew point/apparent temp/humidex, I went in to the .htm file and removed the references to apparent temp and humidex, since I'm not interested in displaying those values.

Everything displays correctly, but when the page loads, it still defaults to apparent temp. I suspect the fix is in one of the gauge javascript files, but I'm not sure where. Can anyone point me in the right direction?

You need to change:

176 g_dew.title = LANG.apptemp_title;
178 g_dew.selected = 'app';

and depending on what you want the default to be in the HTML from line 90 you need to select a new default selected option:

eg.
<input id="rad_dew4" type="radio" name="rad_dew" value="hea" selected onclick="doDew(this);">

I got it to work.

One little nit: how do I have the page load and have the dew point button already selected, like it is for temp and humidity?

I'm no expert, but the code for the temp and and humidity gauges has "checked" in the default items, so I guess that you need to do the same for dew point.

That did the trick! Thanks!

Oops, yes it is checked, not selected. My memory is going! :bash:

Hi Mark,

Same issue here.
I want the gauge to display initially the Humidex value (and not apparent temp).
Changed all the appropriate codes, however it displays the humidex (and it is checked!!) but on the gauge it still displays Apparent
g_dew.title = LANG.apptemp_title;
g_dew.value = 0.0001;
g_dew.selected = 'hum';
When I change it to:
g_dew.title = LANG.humtemp_title;
g_dew.value = 0.0001;
g_dew.selected = 'hum';
it shows NO display (= blank)
What does it need to be changed in???

Thanks,
Arthur

Arthur, this is what you have presently in your 'gauges.js' script (at 14:20 PDT):

Code:

    // define dew point gauge start values
    g_dew.sections = createTempSections(0, true);
    g_dew.areas = [];
    g_dew.minValue = 0;
    g_dew.maxValue = 40;
    g_dew.title = LANG.hum_title;
    g_dew.value = 0.0001;
    g_dew.selected = 'hum';
    g_dew.minMeasuredVisible = true;
    g_dew.maxMeasuredVisible = true;

This is what you need to properly display the humidex factor (not really a temperature per se):

Code:

    // define dew point gauge start values
    g_dew.sections = createTempSections(0, true);
    g_dew.areas = [];
    g_dew.minValue = 0;
    g_dew.maxValue = 50; // changed this value as the humidex can go higher than the temperature
    g_dew.title = LANG.humdx_title; // Arthur this line displays the title within the gauge - note the difference...
    g_dew.value = 0.0001;
    g_dew.selected = 'hum';
    g_dew.minMeasuredVisible = true;  // see comment below
    g_dew.maxMeasuredVisible = true;  // see comment below

Arthur, by default, for the humidex factor setting, the gauge will display neither the maximum nor the minimum measured value - thus placing a true at the end of both 'MeasuredVisible' lines will not activate anything, unless you also modify the code for the humidex factor.

You will need to go down the code of the 'gauges.js' script to lines 1174-1175:

Code:

            g_dew.minMeasuredVisible = false;
            g_dew.maxMeasuredVisible = false;

In my opinion, the only useful information would be to display the maximum measured value (adding the minimum measured value is meaningless and would only clutter the display), thus the new code:

Code:

            g_dew.minMeasuredVisible = false;
            g_dew.maxMeasuredVisible = true;

NOTE: IMPORTANT: Basic precaution! Always, always make a backup copy of the file(s) you are going to edit!

Arthur, after responding to your message, I decided to go a little further ... I modified both my PHP and my JavaScript to 'automate' the change of seasons...

Arthur, first, you have to get more familiar with PHP... :mrgreen:

Then, it is a matter of adding some PHP code into the 'gauges.php' script to determine the season (or rather, to determine if it is summer) and pass on that variable (a switch: true/false) to the 'gauges.js' script - this way, automatically, without further editing, the gauge will display either the apparent temperature (or whatever temperature has been selected as the default) and the humidex factor (or the heat index) during the summer season...

To chose between the heat index and the humidex factor, a second variable (again, a switch: true/false) has to be passed on to the 'gauges.js' script.

Really nice what one can do with a few lines of PHP...

Hi Ray,

I didn't get a Forum notification earlier after your answers (probably didn't checkmark it), so I've been struggling with "humidex, humi, hum, humx etc, etc, until I saw in the autoscaling section the LANG.humdx :oops:

Thanks for the second suggestion (min/max display). I can use this since we have some extreme hum values which top de 40+.......

As for the PHP, I will currently just "click" when seasons change and keep myself first of all focussed on html

Cheers,

Arthur
