Now there is something that disturbs the force a bit. If you zoom out or pan the data on the left or right is disappearing when it cross the y-axis. I wonder how can that be avoided? how can we overlap the data so it doesn't disappear so quick on the left or right side when panning? Some ideas? Thanks Nice Iwo Banaś!

I should use LinearAxis instead of CategoryAxis for zooming of chart. Axis values(labels) do not refresh on scroll.( Do you how to fix it? Thanks, Roman There is an issue with LinearAxis.

Maxim, shoot me an email (find it on my website), and let me know how I can submit this to you. I'm also writing an article about this on my site; with credits to this page.

I'll shoot you an email. I'd like to get this in to FlexLib as we'd talked about before, so if you are cool with that I'll submit it to Doug McCune as a joint effort from Joel, you, and myself.

I like it so much more than Joel's original or the Iwo Banas alternative, since it handles dynamic data providers and appears to handle all the other advanced features of axis renderers flawlessly. The only problem I had, as others have posted about, is that I needed it to work with vertical axes as well. I dug into your code and managed to tweak it to do that, and have tested it quite thoroughly. The only impacted file was ScrollBarAxisRenderer.as, and changes are minimal. I also added a new capability to specify a boolean attribute called "initBarAtEnd." If specified as "true," when the data provider changes, the scroll bar is initialized at the end of the scrolling area rather than the beginning, a feature I also needed. If not specified, or specified as "false," the scroll bar initializes to the beginning of the chart as it always has. Email me if you'd like those changes and I'll send you my modification so you can post it for the others that have expressed interested in a vertical scrolling axis capability. Thx, JJ Max -

I especially like the multiple axis scrolling. I think I may use your component if I need a scrolling chart in the future instead!<br /><br />The only suggestion I would make is that there is no visual indication that there is more data to be viewed; you would have to let the user know that they can drag the chart.<br /><br />Thanks,<br /><br />- max Iwo,

What do you think about my ChartScroller?
