Cumulus Support

Now got 4 months worth and want to see all of it in one graph. Would really appreciate some ideas, I work by reverse engineering these scripts and as a result have trouble getting them to do new things.

I want the temp365 graph to draw a 365 data point x axis and gradually fill it during the year, rather than draw an x axis with 4 months of data and increase it in size each day.

I tried your code and each and every record are plotted - there's no selection to them so they got all selected and plotted. Do you mean you want to have one single record per day containing the min and max temperature per day.

So you'll need to get the last record of each day containing the tempTH and tempTL (highest and lowest temp of that day). That way, you'll plot one bar per day containing the high/low temps. Is that what you want to acheive ?

foreach($rawdata as $key) 
{
    
	    $DATA = preg_split('/ +/', $key);
			
		while($oldesttime < ret_value("time"))
		{			
			$oldesttime = ret_value("time");
			
			$y1[] = ret_value("tempTH");
			$y2[] = ret_value("tempTL");
			$x[] =  ret_value("date");
			$y[] =  ret_value("time");
		}
		
		$oldesttime = ret_value("time");
		$got++;

}

$y1 = array_reverse($y1);
$y2 = array_reverse($y2);
$x = array_reverse($x);
$y = array_reverse($y);

This means that if you have a heavy visitor load, you can use the resulting static images on your pages rather than the php generated ones and only have the processing done at a specific interval.

For example, if you use the level 4 resolution 24 hour charts, they only really need to be generated once every 15 minutes rather than each time someone visits your page.

There are other changes coming including log rotation and ability to use previous months collected data for extended graphs, easier color modification etc..

Can you tell me what parameters must be changed, to make it look this good?
