It appears that TeeChart already serializes public properties on my custom series without me needing to implement ICustomSerialization. When I tried implementing ICustomSerialization, I got an error for a duplicate name (although the name of my property is unique), and so it seemed like the property...

Hello Walt, A custom class, deriving from a TeeChart Series, could be constructed in the following way... Regards, Marc Meumann Thanks! That looks like it is exactly the info I was looking for. I will update my project tomorrow (to implement ICustomSerialization) and let you know. FYI, the followin...

I'm trying to derive my own series from a TeeChart.NET series type (I want to be able to do this for various series types, actually) and then in my derived class, I add my own custom properties. I need the custom series to be serialized to and deserialized from a .TEN file. This seemed to work ok in...

Thanks very much!

I have another performance issue I hope you guys can address (it occurs in the latest v2 release). I have been experimenting with using the ColorGrid series to show my data, which works pretty well except for one thing... I need to display marks when zoomed in on some detailed data (imagine zooming ...

It was still labeled as "June 2005" Also could you please be more specific on this? Where can you find this "label"? Under my client access page for TeeChart.NET v1 (license #8129718). It was an old-style page at this URL: http://www.steema.com/cgi-bin/teegetR.cgi (Old-style as in how your site use...

Yes, you were right, string concatenation was the bottle neck. I've implemented the StringBuilder class in its place... Thanks very much. Although I was disappointed with v1 of TeeChart.NET, I am happy to have the responsive technical support on this forum and that makes me (and my management) a lo...

Evaluation version is already up to date to our latest August 2005 release. It was still labeled as "June 2005", but the file size was bigger, so I installed it and the ".ten" export is indeed faster. However, rendering of the bubble series is still slow and export to Excel is still very, very slow...

Thanks for your observations. In the current release, 2.0.2040.15119, the results for the same tests (in a P4, 2.5GHz, 512Mb RAM) are: Color Grid, 200x200, exporting into a .ten file: about 1 second. Bubble, 40000 points, exporting into a .ten file: about 10 seconds. Are you sure that you checked "...

TeeChart.NET is extremely slow at exporting moderate amounts of data (40k data points). I am using TeeChart.NET v1, but I have tried this with v2 Evaluation as well and it was still extremely slow. 1. Simply open up the demo app (for v1 or v2) and get to a chart editor. 2. Add a ColorGrid series or ...

A. This is related to .NET ListBox and CheckedListBox, just add one of those components to a form, dock the control to some form part and resize it, the flicker will also be present. Isn't there any workaround? Switching tabs stops the flicker, so maybe toggling the visibility of the list box would...

TeeChart cannot be expected to calculate if x or y values are being added in order or not, this has to be specified by the client. Fair enough, but I still think it is weird for some of the colors to show as I was expecting and a few to be random. I am happy to have a fix, but I'm just suggesting t...

It already works with the next maintenance release which is expected to be released this week. That's good news. :D Thanks! Regarding the bubble series colors you should use: series.Color = Color.BurlyWood; series.ColorEach = false; // This will fix the bug: series.XValues.Order = ValueListOrder.No...

I am using TeeChart .NET version 1.1.1879.21176 and animated zoom does not work. I also had an issue with points in a bubble series showing up with random color, but I found a fix in another posting on this forum (but the odd behavior still seems like a bug to me -- I would expect it to work or not ...
