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...

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...

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,

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.

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,

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...
