Hi Infragistics Support,
Can you provide some guidance/tips/suggestions for a new user of your controls?
I have a requirement to display ~400 series. Each with ~6000 points (for a total of ~2,400,000 points). Will Infragistics WPF chart control be able to handle this and still provide a good user experience?
Some other requirements: will need zoom and pan, Series hit testing but not necessarily point (marker) hit testing. I believe the data will normally be evenly spaced in the X direction but cannot guarantee that.
How would Infragistics recommend charting this data to achieve a good user experience (i.e. the char is still "snappy")?
Please let me know if any more information would help. Thanks!
Chris
Hi Graham,
Thanks for further suggestions. We're good with peaks and such - we've got our own library to do all the "heavy lifting" math on the data - we'll just be adding a dozen or so annotations to the chart at the proper places (I will be raising an issue with this later though...).
Chris,
Awesome, glad I could help! Do let me know if you need any more assistance.
One note on the hairline mode, if you guys are also interested in negative peaks, you may want to alter the behavior whereby rather than it picking the min or max as the representative points for a range that it could first compute the median value for the series data, and select either min or max at any given point in time based on whether you are greater or less than the median, and maybe that will ensure that the maxima and minima are well represented.
As for praise, totally not required, just glad I could help! I'll make sure to send my manager this forum thread, though. I believe there is an opportunity to share feedback when we close a case, whether it positive or negative, but I'm not super familiar with the process, myself.

I've gotten a chance to look at what you posted WRT the OrderedScatterLineSeries. First off, thanks again for working with me. Let me know who I should email to give you some public praise! :)
So with the new series type. Seems to be working. :) I can see/feel an improvement in responsiveness. Especially WRT drag zooming. Of course this is all subjective but it does feel faster. We like the hairline so that is a plus. The BitmapCache on/off makes a big difference in performance so we'll stay with it on. In my (limited) playing with the Resolution setting, I found that the loss of resolution was too much for any gains in performance - even going from 1 to 2 I saw smooth peaks going to sharp peaks. And since we're interested in peaks.... that wasn't what we needed so we'll probably stay away from changing that.
So to wrap up, I think we'll stick with your enhancement. At some point soon, I'll try to get to your suggestions page to add this as an enhancement.
Neat, let me know how it goes!
Hi Graham.
This looks cool. I'm deep in the bowels of coding up a module to read NetCDF scientific data files right now so I can't get to this right away. Hopefully this afternoon (I'm in the PST timezone) I'll be able to get to it. If not, Monday. I'll let you know how it goes.
