Description narcís calvet 2015-06-15 04:33:40 EDT 
Histogram series brush overlaps the bottom axis. Making the brush transparent doesn't occur:

      tChart1.Aspect.View3D = false;
      tChart1.Series.Add(new Steema.TeeChart.Styles.Histogram()).FillSampleValues();
      //tChart1[0].bBrush.Transparency = 100;

This also happens with the left axis. It's solved using this:

      tChart1.Axes.Bottom.MinimumOffset:=10;
Comment 2 narcís calvet 2015-07-01 03:33:30 EDT 
Using this code:

     private void InitializeChart()
     {
       Histogram series;
       tChart1.Aspect.View3D = false;
       tChart1.Series.Add(series = new
Steema.TeeChart.Styles.Histogram()).FillSampleValues();

       tChart1.Axes.Bottom.AxisPen.Color = Color.Red;
       tChart1.Axes.Bottom.AxisPen.Width = 0;

       tChart1.Axes.Left.MinimumOffset = 1;
       series.UseYOrigin = true;
       series.YOrigin = 0;
       tChart1.Axes.Left.SetMinMax(0, tChart1.Series[0].YValues.Maximum);
     }

Histogram paints to the bottom position of the left axis by default - scroll the default Histogram up to see this. To get the expected behaviour, set the YOrigin to zero and shift the Offset by a pixel.
