Add A Single Date, Value point to a Tee.Line object
I looked at all the examples and they use AddRandom or pre-populate with Arrays or TextBoxes and such -- I pull a JSON array from a web service then need to iterate through the array and add the values to a Tee.Line object below. The reason I don't just set the array as a datasource is it has many f...

Teechart Can't Handle Dates less than 1900???
DrawingBackwards.png I sell forecasts online and use this chart -- everything's been fine. I created a forecast and dates dip into the 1800's and everything printed backwards on the chart. Here's test code to show the problem: vb.net Dim dtTest as DateTime dtTest = CDate("1/1/1809 2:00 am") Me.TCha...

Re: Update HTML5 Chart with Realtime Stock Quotes
Hi Yeray, Yes I did see that example and that shows how to refresh the chart and redraw real-time. I suppose my question is how does one query a datasource real-time using html 5/javascript. The example seems to generate it's own data and doesn't query a datasource as a stock chart would. Thanks, ja

Update HTML5 Chart with Realtime Stock Quotes
Is there an easy way to pull data from a database and update an HTML chart with real-time stock prices tic by tic without reloading the whole page. I'm using ASP.Net and SQL server. I did this before by using frames with server side code that generated javascript and a timer would load new points bu...

Reference a Series by Name?
I need to add an unknown number of series dynamically -- Then I need to add data to this series (preferably by series name) -- Is there an elegant way to do this without creating a bunch of line objects and referencing those? Example: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As ...

Re: Error opening form with TChart on it.
I found the solution. This project used to reference an old version of teechart. And even though I changed the reference to the new teechart.dll in the project -- When I created a new project from scratch and added the new teechart to it I noticed that in the vbproj file the references were not the ...

Re: Visual Studio 2008
I tried that twice but Visual Studio just shuts down when I click on "Choose Items".
Running VS 2008 SP1.
Perhaps I need to uninstall VS and re-install.
Thanks,
Joseph

Teechart not showing up in ToolBox visual studio 2008
Teechart objects used to show up in Visual Studio 2008 toolbox but after reinstalling teechart and running update TeeChart objects no longer show up in Toolbox.
Is there a simple way to make the "reappear?"
Thanks,

Re: System.Drawing.Color does not implement IXmlSerializable int
Thanks for your solution! I get it now. So I traced through and here's what I think happened -- one of the workstations that upated this project (Using Visual SVN) had updgraded to this version of TeeChart but didn't have the latest update. After this update -- they checked in the solution and then ...

Re: How to graph a function with 3 variables
No,
I think due to it's complexity it's always a report.
Probably I should stick to that or lose a variable.
Because I think I'd have to add more axis or another dimension somehow
and just the thought of that hurts my brain.
Thanks,
ja

Re: How to graph a function with 3 variables
So let's say the Z axis is fuel type "A". And the X axis is fuel type "B" Which axis would be the "Air Mixture"? The Y Axis would be thrust. So even though theirs 3 variables the "Thrust" which is the most important is really the 4th value. So 3 Variables go into the function to predict thrust and I...
