[mapserver-users] RE RE PROCESSING CHART_SIZE_RANGE vaariable substition SOLVED

[Steve.Toutant at inspq.qc.ca]

I didn't find a way to modify the processing statement but in this trac
http://trac.osgeo.org/mapserver/ticket/2136

It seems that minsize maxsize minval maxval are optional, so only itemname 
can be used.
That is a solution to me since I can manage my case on the database side. 
(Just like I do with proportional circle using SIZE=[itemname])

I think the following (from the trac) should be added to the Mapserver 
Dynamic charting doc

Also supports
PROCESSING "CHART_SIZE_RANGE = itemname"
without the minsize,maxsize,minval,maxval values for when the diameter can 
be read directly from an attribute without need for rescaling 

thanks
steve

RE [mapserver-users] PROCESSING CHART_SIZE_RANGE vaariable substition









If it was possible to modify the url it would be fine, such as we can do 
to modify a class 
$url .= urlencode('map.layer['mylayer'].class[0].style[0]=COLOR'). 
'+255+255+255+OUTLINECOLOR+255+255+255&'; 

Is it possible to do the same for processing chart_size_range? 
I've tried without success yet. 
thanks 
steve

[mapserver-users] PROCESSING CHART_SIZE_RANGE vaariable substition











Hi, 
I created a pie chart and use PROCESSING "CHART_SIZE_RANGE=total 10 50 1 
154" 
to define the size of each chart 

I would like to avoid hardcoding minval and maxval since these values can 
change in my application at runtime. 

Is there a way to modify these values using runtime substitution variable 
or programmatically? 
thanks 
steve
