RE: [flexcoders] Flex1.5: Limit of series a graph component can have
I dont think they would want to resample or view chunks of data as a graph detail. This is more a political question. If it can be done, then my managers will trust Flex implicitly. Otherwise, they will force us to use some other product, or even switch to .NET. This financial application is being built for our federal government, and so theres a lot of red-tape going on in this project. So I ask againcan it be done? Thanks in advance.

RE: [flexcoders] Flex1.5: Limit of series a graph component can have
There are no hardcoded limits that I know of, it all comes down to performance - CPU and memory. I'd still like to see an instance of what this sort of graph would look like. Unless you're doing a scatterplot (and given the amount of data you're talking about, perhaps even in that case), its sounding like you're significantly oversampling screen resolution, which doesn't make sense from a graph design perspective. You're not going to be able to read any information out of the plot, it will just look like mud. On a 1000x1000 pixel graph with zero overlap and one pixel per datapoint, you're covering 10% of the available surface area with 100k samples. Of course, you're not actually going to use one pixel per datapoint (as that totally hides extrema), so you're probably getting up into the 50% of the available surface area painted in at this point. There's no information there. Mud. Have you read Edward Tufte's books? I think your best approach (never mind Flex, just in general) is to separate the plotted data from the actual data. Reduce the actual data to a representation that can be plotted and interpreted by humans - bars with high/low extrema, click to zoom, etc. It isn't a failing of Flex that 100,000 datapoints can't reasonably be plotted on a normal chart, its a failing of all normal chart types. You need to come up with a better representation. I could be totally off-base and misinterpreting your needs, though. -rg -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of RAMOS CARDONA JESUS SALVADOR Sent: Tuesday, April 11, 2006 8:22 AM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Flex1.5: Limit of series a graph component can have I don't think they would want to resample or view chunks of data as a graph detail.

RE: [flexcoders] Flex1.5: Limit of series a graph component can have
Thank you for your answer, Roger. I agree with the uselessness of a 100k point chart, and I have had long arguments with my superiors regarding the actual need of this, but I backed out after I was introduced to the political issues regarding this project. As I stated before, this is more a political issue than a practical issue. Regards.

RE: [flexcoders] Flex1.5: Limit of series a graph component can have
Is it possible? Yes. Will it have reasonable performance? Probably not, but it's a really easy test to find out. Charts probably will not perform well under this load, but I'm not sure you'll even get that far. First you have to send 200k floats over the wire, and deserialize them in the player, which has its own performance problems. So, I'd say, write a quick test and see how it feels. But in general, I'd agree with Roger, you're better off aggregating your data in some way and displaying that. If that's not an option, then you might want to seek out other alternatives. (btw, if you want to use flex, one reasonable alternative would be to use flex for the application, but generate the chart on the server using one of the many server side chart generation packages out there that render to bitmaps, and just displaying the bitmap in the flex app).

If he is willing to support Flash Player 8, you can utilize the Bitmap API's to blit the graph to a bitmap representation. Pro? Infinite amount of dots can be drawn. Con? Printing will look horrible. It'll take some work to make the graph have it's area capturable, as well as modifiying the dataProvider to scale to that amount... but it could be done. - Original Message - From: Roger Gonzalez To: flexcoders@yahoogroups.com Sent: Monday, April 10, 2006 9:35 PM Subject: RE: [flexcoders] Flex1.5: Limit of series a graph component can have That would be pretty impractical in Flex 1.5 without providing truckloads of RAM.
