I've just traced through the code for Ext.chart.Chart.save() and found that ultimately the SVG is posted to a hard-coded URL at svg.sencha.io obviously this is completely unworkable for a commercial application so I was wondering if there was any intention to make the conversion-server configurable before the release of Ext 4.1? Obviously I can override Ext.draw.engine.ImageExporter and use something like ImageMagick to convert server-side but I was wondering if there was going to be a official solution that didn't involve sending client graph data to Sencha?
