Hello. Been collecting data for my jpgraphs since recieiving a weather station for Christmas
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.
Here is one that I'm working on
http://www.djmorgan.org.uk/weather/graphs/temp365.php(it's to go with these
http://www.djmorgan.org.uk/weather/graphs/graph.php)
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.
Here is the php
--------------------------------------------
<?php
require_once("GraphSettings.php");
check_sourceview(); # Checks to see if Source View Was passed to the script
$rawdata = array_reverse( file("dayfile.txt"));
// $rawdata = str_replace("," , "." , $rawdata);
// $rawdata = str_replace(";" , " " , $rawdata);
// $rawdata = str_replace("/" , "-" , $rawdata);
$rawdata = str_replace("," , " " , $rawdata);
$rawdata = str_replace("/" , "-" , $rawdata);
$y1 = array();
$y2 = array();
$x = array();
$wanted = 366;
$got = 0;
foreach($rawdata as $key) {
if ($got < $wanted) {
list($date, $gust, $gustbearing, $Tgust, $mintemp, $Tmintemp, $maxtemp, $Tmaxtemp,
$minbaro, $Tminbaro, $maxbaro, $Tmaxbaro, $maxrainrate, $Tmaxrainrate, $dayrn,
$avgtemp, $windrun) = preg_split('/ +/', $key);
$y1[] = $maxtemp;
$y2[] = $mintemp;
$x[] = substr($date,0,2);
$got++;
}
}
$y1 = array_reverse($y1);
$y2 = array_reverse($y2);
$x = array_reverse($x);
