i am preparing graphs(MatPlotLib) related files using external methods., when i test them on zope they display very well there.
But when i call these external methods using tal as:
<Img tal:attributes="src python: context.IterationBar(context) "/> where IterationBar is my external method that displays a BarChart.
Or using
<img src="/Agile/image.gif" tal:attributes="src context.IteartionBar(context)"/>
1) the thing you're calling must return an *URL* not the image data itself...think about how the <img> in HTML works
2) The script called through the given url must return the image data _and_ it must set the proper http headers content-type, and content-length
If your site is only for FireFox or evolved browser you can use inline rendering: <img width="81" height="85" src="data:image/gif;base64,R0lGODlhUAAPAKIAAAsLav///88PD9WqsYmApmZmZtZfY mdakyH5BAQUAP8ALAAAAABQAA8AAAPb
