Description narcís calvet 2015-07-31 04:58:23 EDT

Using the code below with stack horizontal bars, scrolling the chart down series disappear. The problem is with BarHeightPercent property. Setting it to its default value works fine.

      Steema.TeeChart.Styles.HorizBar[] hbar = new Steema.TeeChart.Styles.HorizBar[20];

      for (int i = 0; i < 20; i++)
      {
        hbar[i] = new Steema.TeeChart.Styles.HorizBar(tChart1.Chart);

        hbar[i].MultiBar = Steema.TeeChart.Styles.MultiBars.SelfStack;
        hbar[i].BarHeightPercent = 5;
        hbar[i].Marks.Visible = false;

        for (int j = 0; j < 3; j++)
        {
          Color cl = (j == 1) ? Color.Green : Color.Red;

          hbar[i].Add(1, cl);
        }
      }

Same happens with equivalent Bar series example:

      //Steema.TeeChart.Styles.HorizBar[] hbar = new Steema.TeeChart.Styles.HorizBar[20];
      Steema.TeeChart.Styles.Bar[] hbar = new Steema.TeeChart.Styles.Bar[20];

      for (int i = 0; i < 20; i++)
      {
        //hbar[i] = new Steema.TeeChart.Styles.HorizBar(tChart1.Chart);
        hbar[i] = new Steema.TeeChart.Styles.Bar(tChart1.Chart);

        hbar[i].MultiBar = Steema.TeeChart.Styles.MultiBars.SelfStack;
        //hbar[i].BarHeightPercent = 5;
        hbar[i].BarWidthPercent = 5;
        hbar[i].Marks.Visible = false;

        for (int j = 0; j < 3; j++)
        {
          Color cl = (j == 1) ? Color.Green : Color.Red;

          hbar[i].Add(1, cl);
        }
      }
