ExtJS 4的堆积和分组图表

Question

I'm trying to convert from Fusion Charts to the builtin ExtJS 4 charts and I can't find a way to create a Stacked and Grouped Chart . Has anyone been successful getting this to work with ExtJS 4?

Answer 1

It doesn't look like this is possible with the bundled charting in ExtJS. I'd recommend High Charts or Fusion Charts.

Answer 2

I found the solution, You should add the second bar series and for each use render handler like this:

renderer: function(sprite, config, rendererData, index){ var w = config.width;
config.width = 30;
config.x = config.x + (w-30)/2 - 20; <--- -20 for first bar and + 20 for second

}
