And for whatever it is worth here are the conversions for second and third order polynominals. 'y = a(2)*x^2 + a(1)*x + a(0) 'y-ymin = b(2)*(x-xmin)^2 + b(1)*(x-xmin) + b(0) a(2) = b(2) a(1) = b(1) - 2*b(2)*xmin a(0) = b(2)*Math.Pow(xmin,2) - b(1)*xmin + b(0) + ymin 'y = a(3)*x^3 + a(2)*x^2 + a(1)* ...

Ahh! I am also very interested in the answer to your question. However, awaiting the 'correct solution', you might be able to workaround your problem by plotting the data with "one" increment and then use custom labels to put on correct labels. TChart2.Axes.Left.Labels.Items.Clear() TChart2.Axes.Lef...

Well, since I am using FillRectangle and also have the fear that it could be my program logic that has become unstable I did the legwork and installed the earlier version, "TeeChartNET2010VSNET2010_4.0.2011.02083". The old 4.0 version fills the rectangle as expected (from the documentation), from (X...

What about custom labels. Will that solve your problem? TChart1.Axes.Left.Labels.Items.Clear() TChart1.Axes.Left.Labels.Items.Add(MIN, MIN.ToString())'or Format( TChart1.Axes.Left.Labels.Items.Add(MIN, MAX.ToString()) *I have not checked that piece of code myself. I use it to place logarithmic label...

In my AfterDraw for a TChart I used g.FillRectangle(New SolidBrush(Color.FromArgb(128, Color.DarkOrange)), rect.X, rect.Y, rect.Width,rect.Height) I used this to draw a rectangle from where I first clicked to the current mouse position. However, after installing the latest (TeeChartNET2010VSNET2010_...
