New Post: Is it possible to set your own interval on a logarithmic scale?

I don't understand completely your question, but at first glance: won't it be enough for you to set the Maximum/Minimum of the axis?

                LogarithmicAxis axis1 = new LogarithmicAxis();
                axis1.Position = AxisPosition.Bottom;
                axis1.Base = 8;
                axis1.MinorStep = 2;
                axis1.MinorGridlineStyle = LineStyle.Dot;
                axis1.MinorGridlineColor = OxyColors.LightGray.ChangeAlpha(20);
                axis1.Minimum = 0;
                axis1.Maximum = 32800;

                plotter.Model.Axes[0] = axis1;
                plotter.RefreshPlot(true);

Results:

Log2


Log8


Log10




I think you can't retrieve the label for minor ticks right now, correct if I'm wrong.

By the way: why would you set the base to "e"? Its logical to obtain "random" values (e^2, e^3...)
