INSTRUCTIONS
	To create thumbnail trend graphs ('Sparklines') on webpages using webtags from Cumulus.

	http://sandaysoft.com/

1) If you are already using cumuluswebtags add the contents of sparkline_tags.txt to your cumuluswebtags.txt file.

2) If you have no existing webtags file, Save 'sparkline_tags.txt'  and have Cumulus Process and Upload as sparkline_tags.php
	In spark.php change the path to your webtags file.
	FOR EXAMPLE:
	include("/sparkline_tags.php");
	OR
	include($_SERVER["DOCUMENT_ROOT"] . "/cumulus/cumuluswebtags.php");

3) Upload to your WEBSPACE in the directory of your choice:
	jquery.min.js 
	jquery.sparkline.min.js
	spark.php
	
4) Add to the WEBPAGE that requires Sparklines:
	<script type="text/javascript" src="http://YOURPATH/jquery.min.js"></script>
	<script type="text/javascript" src="http://YOURPATH/jquery.sparkline.min.js"></script>
	<script type="text/javascript" src="http://YOURPATH/spark.php"></script>
	
5) Insert one of the following in html at the location you wish the relevant Sparkline to appear:
	 <span class="temp">..</span>
	 <span class="wind">..</span>
	 <span class="rain">..</span>
	 <span class="solar">..</span> Only if supplied by weather station.
	 <span class="baro">..</span>
	 <span class="windd">..</span> 'Pie' chart of average wind direction.
	 <span class="heat">..</span>
	 <span class="hum">..</span>
	 <span class="dew">..</span>
	 <span class="chill">..</span>
	 <span class="gust">..</span>
	 <span class="winddir">..</span>
	 
6) If no Sparklines appear: 
	Check sparkline_tags.php is populated on webserver. 
	If 'View Source' of page shows Variables to be empty or zero, check Name/Paths of webtag file.
		 
7) Customisation:
	a) Under user variables in spark.php there are limited colour choices.		
	b) $width = 60; //Graph width   $height = 16;//Graph height - Set the desired width and height of the Sparkline - Should not be larger than the holding container!
	c) $cnt = 12; //number of data points/tags for graph. This allow the number of webtags/datapoints on the graph to be changed. Default is 12 with supplied tags.
	d) $param = array( temp, rain, wind, solar, baro); // <span> names - Add other parameters here - ensuring webtags are created FIRST !. 
	   Other parameters may be created and added here ensure additional webtags are created and number must equal $cnt.
	e) Time intervals may be changed by editing sparklines_tag.txt (See Cumulus Wiki - http://wiki.sandaysoft.com/a/Webtags)
	f) A page using colours/tags as supplied here can be seen at http://lethamshank.co.uk/met/localwx.htm?page=current
