Re: [xwiki-users] Chart Macro not displaying within page

[Adam Kozuch]

This is my syntax for the page I was using to test out the charting:

{{html clean="true"}}
<div class="graphs">
<img src="
http://10.100.229.50:8080/xwiki/bin/download/SD/QueryPage/testgraph.png";
alt="graph"
title="SOME GRAPH"
height="300"
width="400"/>
</div>
{{/html}}

{{chart type="line" source="inline" params="range:B2-C6;series:columns;"
title="Chart Test" width="320" height="240"}}
|  |X  |Y  |Z
|Q1|1.2|3.4|1.3
|Q2|4.5|3.4|2.3
|Q3|1.2|4.5|9.0
|Q4|3.4|1.2|1.2
|Q5|1.5|2.0|
{{/chart}}

{{chart type="bar"
params="document:SD.Data;table:table1;range:B2-D5;series:columns;"
title="Chart Two" width="320" height="240"/}}

{{velocity}}
{{chart source="inline" type="bar" params="range:B2-B7;series:columns;"
title="Square"}}
| |Square
  #foreach($i in [1..6])
|${i}|$mathtool.pow($i, 2)
#end
{{/chart}}
{{/velocity}}

I was trying all sorts of different charting methods to see if it was simply
how I was writing the macro or maybe something obscure I was missing. The
very top one was just to test and see if my browser couldnt display the
image, so I attached a .png but that displayed fine across all browsers so I
knew that it was something chart or server related.

All that the charts would display as was a html link which led to an empty
page. The charts were showing up in the 'charts' directory in our Tomcat
server, I could see them when I opened them server side, but for some reason
they just couldn'd be displayed on the xwiki page.

Hope this helps?
