Spent some time today on the google chart. To click the "Link to this view", you could get the link carries your setting, you could embed in the <iframe> tag. But it is whole google finance page. There is a way to make the display area small enough to just fit the chart and pre-set the scroll position to just show the chart in the view (to make it looks like just a chart nothing else), that requires javascript. But WenXueCity seems block any javascript coding.
The google chart is a Flash Player, very complicated to enbed, unless there is api. Even google has that api, most likely need to have javascript to run.
So, the easy way is to screen shot the chart, then upload and attach the image file.
