Hi Ivan,
I like your idea, with one minor change. What about:
defaults: {
imageFormat: 'image/png',
baseParams: {
'legendOptions': 'forceLabels:on'
}
}
baseParams is a common property in Ext, so I'd be in favor of this (and not
vendorParameters).
It would be great if you could open a ticket for this, and a patch would be
greatly appreciated.
Regards,
Andreas.
