If I select a log scale on a points chart with a log scale of minimum 0.1 and maximum 100 (3 cycle), the log scale (tick marks) from 0.1 to 1 will not display. The log scale from 1 to 10 and 10 to 100 displays correctly. Can you confirm this is a bug?

' Case Log Linear
Points1.Chart.Axes.Right.Logarithmic = True
Points1.Chart.Axes.Right.LogarithmicBase = 10
Points1.Chart.Axes.Left.Logarithmic = True
Points1.Chart.Axes.Left.LogarithmicBase = 10
Points1.Chart.Axes.Bottom.Logarithmic = False
Points1.Chart.Axes.Top.Logarithmic = False
' End Select

Points1.Chart.Axes.Left.Maximum = 100
Points1.Chart.Axes.Left.Minimum = 0.1
Points1.Chart.Axes.Right.Maximum = 100
Points1.Chart.Axes.Right.Minimum = 0.1

Hello lilo,

I can not reproduce your problem using next code:

Code: Select all

      Steema.TeeChart.Styles.Points points1;

      private void InitializeChart()
      {
          points1 = new Points(tChart1.Chart);
          for (int i = 1; i < 100; i++)
          {

              points1.Add(i, Math.Log(i));

          }
          points1.VertAxis = VerticalAxis.Both;
          tChart1.Axes.Right.Logarithmic = true;
          tChart1.Axes.Right.LogarithmicBase = 10;
          tChart1.Axes.Left.Logarithmic = true;
          tChart1.Axes.Left.LogarithmicBase = 10;

          tChart1.Axes.Left.Automatic = false;
          tChart1.Axes.Left.Minimum = 0.1;
          tChart1.Axes.Left.Maximum = 100;
          tChart1.Axes.Right.Automatic = false;
          tChart1.Axes.Right.Minimum = 0.1;
          tChart1.Axes.Right.Maximum = 100;
      }

Could you tell us if previous code works in your end? If it doesn't work in your end, please modify the problem because we can reproduce your problem.

Thanks,
