Hi,
we’re creating a flash chart engine, something that could be compared to Google Finance’s engine (http://finance.google.com). all is well, except that the engine gets rather slow when the amount of values is big eg. 10 000 or something. I know that it’s not an easy task to achieve, but we need to do it.
ATM, we’re creating a dynamic linechart, which can have multiple target whose values need to be printed out. We’re drawing the line with the Drawing API. I’m just wondering, how Google managed to do their charting engine. It’s incredibly smooth, eventhough it has quite an amount of values to pront out.
In addition, does anyone have any idea on how to do tweening when the timeline changes. In Google Finance, when you change the length of the viewable timeline by dragging, the change is ultimately animated. How’d that happen?
