I am facing below challenges
1)Can i show a custom y axis as you can see in image little *Red* V icons
2) Also is there a way i can shade gray couple horizontal bars e.g i want to shade alternate 5 bars

This is i am able to achieve.

Hello,

Very roughly, you could start by something a little like this:

Code: Select all

    Steema.TeeChart.Styles.HorizBar hBar;
    Steema.TeeChart.Tools.GridBand band;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tChart1.Legend.Visible = false;
      hBar = new HorizBar(tChart1.Chart);
      hBar.FillSampleValues(20);
      hBar.Marks.Visible = false;

      band = new GridBand(tChart1.Chart);
      band.Axis = tChart1.Axes.Left;
      band.Band1.Color = Color.White;
      band.Band2.Color = Color.LightGray;

      tChart1.Panel.MarginLeft = 10;

      Axis leftAxis = tChart1.Axes.Left;
      leftAxis.Increment = 5;
      leftAxis.AxisPen.Visible = false;
      leftAxis.Labels.Font.Color = Color.Transparent;
      leftAxis.Ticks.Visible = false;
      leftAxis.MinorTicks.Visible = false;

      tChart1.AfterDraw += TChart1_AfterDraw;
    }

    private void TChart1_AfterDraw(object sender, Graphics3D g)
    {
      g.Pen.Color = Color.Red;
      g.HorizontalLine(0, tChart1.Axes.Bottom.IStartPos, tChart1.Axes.Left.IStartPos);
      g.TextOut(20, tChart1.Axes.Left.IStartPos - 12, "text");

      int fourthBar = hBar.CalcYPos(4);

      g.Brush.Color = Color.Red;
      g.Triangle(new Point(30, fourthBar), new Point(40, fourthBar), new Point(35, fourthBar + 10), 0);
    }

Thanks Chris for your help.

Is there a way i can cover exactly 5 bars by gridband. As of now Gridband start middle of ticks
Also i am not able to get rid of bottom axes and the spaces highligted in Red

Note: Left Axis ticks are temporary

Code: Select all

Chart chart = param.ChartInstance;
            TChart tchart = param.TeeChart;
            tchart.AfterDraw += tchart_AfterDraw;
            tchart.Aspect.View3D = false;
            chart.Axes.Custom.Clear();

            for (int i = 0; i < 3; i++)
            {
                Steema.TeeChart.Styles.HorizBar loanBar = new HorizBar(chart);
               // loanBar.BarHeightPercent = 100;
                //Bar mstarForecastedLosses = new Bar(chart);
                //Bar mstarBearishLossesBar = new Bar(chart);

                loanBar.FillSampleValues(20);
                //mstarForecastedLosses.FillSampleValues(4);
                //mstarBearishLossesBar.FillSampleValues(4);

                loanBar.MultiBar = Steema.TeeChart.Styles.MultiBars.Stacked;
              //  loanBar.SideMargins = false;
                loanBar.Legend.Visible = false;
                loanBar.Marks.Visible = false;
              //  mstarForecastedLosses.MultiBar = Steema.TeeChart.Styles.MultiBars.Stacked;
              //  mstarBearishLossesBar.MultiBar = Steema.TeeChart.Styles.MultiBars.Stacked;

                loanBar.VertAxis = Steema.TeeChart.Styles.VerticalAxis.Left;
                loanBar.HorizAxis = Steema.TeeChart.Styles.HorizontalAxis.Top;
            }

                

            chart.Header.Visible = false;
          //  chart.Panel.Color = Color.Blue;
           // chart.Panel.BorderRound = 5;

            //chart.Panel.MarginBottom = 0D;
            //chart.Panel.MarginLeft = 4.0D;
            //chart.Panel.MarginRight = 0D;
            //chart.Panel.MarginTop = 0D;
            //chart.Panel.MarginUnits = Steema.TeeChart.PanelMarginUnits.Pixels;


            Axis top = new Axis(true, false, chart);
            chart.Axes.Custom.Add(top);
            top.Grid.Visible = true;

            band = new GridBand(chart);
            band.Axis = tchart.Axes.Left;
            band.Band1.Color = Color.White;
            band.Band2.Color = Color.LightGray;

            tchart.Panel.MarginLeft = 7;

            Axis leftAxis = tchart.Axes.Left;
            leftAxis.Increment = 5;
            leftAxis.AxisPen.Visible = false;
            leftAxis.Labels.Font.Color = Color.Blue;
            leftAxis.Ticks.Visible = true;
            leftAxis.MinorTicks.Visible = true;
            leftAxis.Grid.Visible = true;

            Axis bottomAxis = tchart.Axes.Bottom;
            bottomAxis.AxisPen.Color = Color.Transparent;
            bottomAxis.AxisPen.Visible = false;
            bottomAxis.Labels.Font.Color = Color.Transparent;
            bottomAxis.Ticks.Visible = false;
            bottomAxis.MinorTicks.Visible = false;
            bottomAxis.Grid.Visible = false;

Hello,

You're very welcome.

Possibly the quickest way to achieve this is again to draw elements on the chart, e.g.

Code: Select all

    Steema.TeeChart.Styles.HorizBar hBar;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tChart1.Legend.Visible = false;
      hBar = new HorizBar(tChart1.Chart);
      hBar.FillSampleValues(20);
      hBar.Marks.Visible = false;
      tChart1.Panel.MarginLeft = 10;
      tChart1.Axes.Left.Visible = false;
      tChart1.AfterDraw += TChart1_AfterDraw;
      tChart1.BeforeDrawAxes += TChart1_BeforeDrawAxes;
    }

    private List<int> val = new List<int>();
    private void TChart1_BeforeDrawAxes(object sender, Graphics3D g)
    {
      val.Clear();

      for (int i = 1; i < hBar.Count; i+=5)
      {
        double middle = (hBar.YValues[i] - hBar.YValues[i - 1]) / 2.0;
        val.Add(hBar.CalcYPosValue(hBar.YValues[i - 1] - middle));
      }

      Rectangle r;

      for (int i = 1; i < val.Count; i++)
      {
        Color col = i % 2 == 0 ? Color.White : Color.LightGray;
        g.Brush.Color = col;
        g.Pen.Color = col;
        r = Utils.FromLTRB(tChart1.Axes.Bottom.IStartPos, val[i - 1], tChart1.Axes.Bottom.IEndPos, val[i]);
        g.Rectangle(r);
      }
    }

    private void TChart1_AfterDraw(object sender, Graphics3D g)
    {
      g.Pen.Color = Color.Red;
      g.HorizontalLine(0, tChart1.Axes.Bottom.IStartPos, tChart1.Axes.Left.IStartPos);
      g.TextOut(20, tChart1.Axes.Left.IStartPos - 12, "text");

      int fourthBar = hBar.CalcYPos(4);

      g.Brush.Color = Color.Red;
      g.Triangle(new Point(30, fourthBar), new Point(40, fourthBar), new Point(35, fourthBar + 10), 0);
    }

Legend and Chart top is overlapping , Also grid lines are not showing from top axis

Hello,

Would you please be so kind as to retouch your example so I can compile and run it here? I'm afraid I do not have access to your ChartBuilderParam object.

here is the source code - https://github.com/dekajp/DealViewChartApp

[Christopher]

Hello,

Thank you for your code. The problem can be corrected by adding one line to SetCommonProperties():

Code: Select all

            tchart.Legend.CustomPosition = true;
            tchart.Legend.Top = 10;
            tchart.Legend.Left = 30;

            tchart.Panel.MarginTop = 10;

The reason the MarginTop is necessary is because you have set CustomPosition to true.

Thank You , this worked
