I have a couple of questions which both relate to loading data into a series. First, there is an overload of the series.Add method which takes a List as the parameter passed in (public Void Add(System.Collections.IList)). How does that version of the Add method work? That list is expected to be a co...

Ok that did it.
I was referencing the property as LinePen.DrawingPen.DashPattern in the code that I had been trying.
That property does exist but does not change the appearance of the line style like the new LinePen.DashPattern does.

Thanks for helping me figure that one out.

I have installed the newest eval version to attempt to test the DashPattern support. The new version seems to be performing exactly the same way the old one was. Do you have an sample that demonstrates the new DashPattern support so I can see how this is implemented and used? I just want to make sur...

I am currently using a Point series to plot our data the way you mentioned. There is just a dramatic speed increase with the FastLine series using the ShowAllPoints setting. If there was such a thing that would allow us to only draw a particular point one time with a point series, that would really ...

Thanks for the update Narcis. Yes, I did try the downsampling function but it changes the appearance of the graph too much for what we need to do. We are looking at data where even small fluctuations are important to note. The downsampling makes the graph considerably different looking under any of ...

I have installed and begun using the full feature eval version of the latest .NET component. This has been a big help in letting us use the functions built in to TeeChart as well as some other features that we will eventually need to have in our application. This is really helping us in our task of ...

Once again, I run into the situation where I try for a while without success to find my own answer, post my question and a few minutes later I find the answer I was looking for all along.

The IStartPos and IEndPos values for the Axes.Left and Axes.Top get me the information that I wanted.

I am currently trying to find the proper properties on the TeeChart control to access to obtain information about the size and location of the actual plot area on the control. What I am looking for is the position of the upper left corner of the actual plot area (the part contained within the axes, ...

C++ Builder 5 is what is used here. I am not tremendously familiar with Builder myself. I am the one who will be doing the new development in C# in VS.NET. I will check out the full feature eval version. Not sure how long it will take for us to get out test done but it would be nice to have the full...

The full licensed version that we currently have is TeeChart Pro v7 for C++ Builder. The features demo for that version does not appear to contain the item you described (or at least it doesn't seem to be in that location in this demo). We are in the process of evaluating the trial version of the .N...

The FastLine series looks pretty decent from the performance point of view but for what we are trying to do, it does not work. We need to have the ability to display the series as points and/or line and the FastLine series does the line part well enough but gives us no Pointer ability at all. If the...

We are seeing very slow repaint times as well. I am sure it has a lot to do with the large amount of data that we are plotting in some instances (several million points) but wanted to see if BerntR had any success with creating his own paint method to improve the repaint speed at all? We have a cust...

Thanks again for the response. Is there a schedule for the maintenance release? Or at least a general idea of how often they typically occur? We are in the process of evaluating how well the .NET version of TeeChart will meet our plotting needs for a new application we wish to develop. The addition ...

The code that you show there works just fine for the 5 pre-defined dash styles (Solid, Dash, Dot, DotDash and DotDotDash). However, the option that I was asking about which is NOT working is the System.Drawing.Drwaing2D.DashStyle.CUSTOM. When you select Custom, you should be allowed to specify a Das...

I have a Line series that I am attempting to set the Style to be the System.Drawing.Drawing2D.Custom DashStyle. It does not appear that the chart is plotting the line using the DashPattern that I set under the .LinePen.DrawingPen.DashPattern property. The line in the chart looks to be nothing but si...
