Narcis, This is not so easy as the code requires many pieces of hardware to operate correctly. What I can tell you is that the chart is configured with eight (8) fastline series, each getting 10,000 points. I have varied the number of points for all series from 1000 to 10000 and still receive the er...

Hello, I am getting an infrequent error using TChart .NET and the fastline series. I am plotting up to 8 fastline series elements on the chart, and sometimes get an error message that generates a red-X through the TChart control. I captured the .NET error info but cannot seem to make sense of it. Li...

Hi, I'm plotting vectors that are around 10,000 points in length. I set ShowAllPoints to false to speed up the plotted (there are only so many pixels on the screen). I was wondering if it would be possible to change the decimation algorithm so that when it picked 1 point out of 10 possible points to...

Hello, Thanks you for the help, this worked. I also discovered that to scale a polar chart was not obvious, it took the following commands: this.tChart1.Axes.Left.Maximum = maxValue; this.tChart1.Axes.Left.Minimum = minValue; The confusing part for me was that the Axes.Left perfoms the radius scalin...

Hello, I'm back again with another simple (hopefully not too stupid) question. How do you programatically set the individual (i.e. left, right, ...) polar plot axes scale visability? I see how to set all the axes scale visibility (i.e. this.polar1.Chart.Axes.Visible = true;), but cannot get the indi...

Hello, I have a request to make for tChart's method of data decimation. It seems as if tChart's current process for decimating data (i.e. this.fastLine1.DrawAllPoints = false;) is to take the first-of-N, as opposed to taking the max-of-N (or peak). I am currently working with VERY large datasets (50...

Hello, This is what I understood for adding complete magnitude and angle arrays to the polar plot (this.polar1.Add(angValues, magValues);), but the polar plot does not seem to display the values. Is there some additional commands to make the polar plot display properly? The following is a larger seg...

Thank you very much. I was trying to put arrays into the polar plot via the add using the following commands: this.polar1.Add(angValues, magValues); where magValues and angValues are arrays that have been give their respective data points. Is there a method to put complete arrays in? Thanks again fo...

Hello,

I cannot seem to get data displayed correctly to a polar plot. Could you please provide an example of how this is accomplished, please do not use the "this.polar1.FillSampleValues(100)" command.

Thank you.

This way: fastLine.Clear(); fastLine.Add(x_values, rawData.fData); Or this way: fastLine.Clear(); fastLine.DrawAllPoints = false; fastLine.XValues.Count = x_values.Length; fastLine.XValues.Value = x_values; fastLine.YValues.Count = y.Length; fastLine.YValues.Value = y; tChart.Refresh(); PLEASE PLEAS...

I'm plotting data that I receive from a thread that is not the same thread that created the chart and the fastline. Is this a problem?

Marc, Because I could no longer get support while still evaluating TeeChart, I spent the bucks and bought TeeChart and Pro Support. I have downloaded and installed the "late January" release. I do not see where the Add for colorgrid has been overloaded to support arrays. I need to plot a color spect...
