Hi Team,

I have a 3D chart where on the x axis I have the range from -15 to 15. Now what I want is to have  different ranges on the axis, the half of my axis is to have a range from 15 to 10(left to right) and then again the later half of my axis should have a range of 10 to 15(from left to right).

How can I achieve this using nevron. Hope its not confusing. Please let me know if more clarification is needed on this.

Hi Manal,
Yes you need to use different axes - the control does not support irregular scales.

Hi,

I created the axis like this:
var axis = ((NCartesianAxisCollection)cartesianChart.Axes).AddCustomAxis(AxisOrientation.Horizontal,
      AxisDockZone.FrontTop);

But the axis is at the fixed position while I want the axis to stay on the chart wall as I rotate my 3D chart and wall changes its position to have the best visibility. how do i achieve that

Hi,
This is the code that I used to produce the axes for this scenario:


And this is the code that I used:
private List<NAxis> ConfigureXaxis(string title)
   {
    NLinearScaleConfigurator scaleX = new NLinearScaleConfigurator();
    scaleX.RoundToTickMax = false;
    scaleX.RoundToTickMin = false;
    scaleX.Title.Text = title;
    scaleX.Title.TextStyle.TextFormat = TextFormat.XML;
    scaleX.MajorGridStyle.ShowAtWalls = new ChartWallType[] { ChartWallType.Floor, ChartWallType.Back };
    scaleX.MajorGridStyle.LineStyle.Pattern = LinePattern.Dot;
    _cartesianChart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = scaleX;
    _cartesianChart.Axis(StandardAxis.PrimaryX).Anchor = new NAutoSideAxisAnchor(AxisOrientation.Horizontal);
    _cartesianChart.Axis(StandardAxis.PrimaryX).View =
      new NRangeAxisView(new NRange1DD(-_xAxisRange / 2, _xAxisRange / 2), true, true);

    var axes = new List<NAxis>();
    axes.Add(AddScale(_cartesianChart,0,45));
    axes.Add(AddScale(_cartesianChart,55,100));
    return axes;
   }

   private NAxis AddScale(NCartesianChart cartesianChart, double begin, double end)
   {
    NLinearScaleConfigurator scaleX = new NLinearScaleConfigurator();
    scaleX.RoundToTickMax = false;
    scaleX.RoundToTickMin = false;
    scaleX.MajorGridStyle.ShowAtWalls = new ChartWallType[] { ChartWallType.Floor, ChartWallType.Back };
    scaleX.MajorGridStyle.LineStyle.Pattern = LinePattern.Dot;
    var axis = ((NCartesianAxisCollection)cartesianChart.Axes).AddCustomAxis(AxisOrientation.Horizontal,
      AxisDockZone.FrontBottom);
    axis.Visible = true;
    axis.Anchor = new NBestVisibilityAxisAnchor(AxisOrientation.Horizontal);
    axis.Anchor.BeginPercent = (float)begin;
    axis.Anchor.EndPercent = (float)end;
    axis.ScaleConfigurator = scaleX;

    return axis;
   }


Now I want to make the axis from -10 to 10 disappear and merge the other to axis n the same line and keep the "X-axis Title" as it is.
Can you help me in this.
Regards
Manal.

Hi Manal,
In short you need to have the two axes share the same axis zone level which is achieved by setting the CreateNewZoneLevel property of the Anchor to false, then you need to have another axis that shows the title at the center - for example:
   NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];

    NBarSeries bar1 = new NBarSeries();
    bar1.Values.Add(10);
    bar1.Values.Add(20);
    bar1.Values.Add(30);
    bar1.Values.Add(40);
    chart.Series.Add(bar1);

    NBarSeries bar2 = new NBarSeries();
    bar2.Values.Add(10);
    bar2.Values.Add(20);
    bar2.Values.Add(30);
    bar2.Values.Add(40);
    chart.Series.Add(bar2);

    NBarSeries invisibleBars = new NBarSeries();
    invisibleBars.Values.Add(0);
    invisibleBars.FillStyle = new NColorFillStyle(Color.Transparent);
    invisibleBars.BorderStyle.Width = new NLength(0);
    chart.Series.Add(invisibleBars);

    chart.Axis(StandardAxis.PrimaryX).Visible = false;

    NAxis xAxis1 = ((NCartesianAxisCollection)chart.Axes).AddCustomAxis(AxisOrientation.Horizontal, AxisDockZone.FrontBottom);
    NDockAxisAnchor dockAnchor1 = new NDockAxisAnchor(AxisDockZone.FrontBottom, false);
    dockAnchor1.BeginPercent = 0;
    dockAnchor1.EndPercent = 50;
    dockAnchor1.CreateNewZoneLevel = false;
    xAxis1.Anchor = dockAnchor1;

    bar1.DisplayOnAxis(StandardAxis.PrimaryX, false);
    bar1.DisplayOnAxis(xAxis1.AxisId, true);

    NAxis xAxis2 = ((NCartesianAxisCollection)chart.Axes).AddCustomAxis(AxisOrientation.Horizontal, AxisDockZone.FrontBottom);
    NDockAxisAnchor dockAnchor2 = new NDockAxisAnchor(AxisDockZone.FrontBottom, false);
    dockAnchor2.BeginPercent = 50;
    dockAnchor2.EndPercent = 100;
    dockAnchor2.CreateNewZoneLevel = false;
    xAxis2.Anchor = dockAnchor2;

    bar2.DisplayOnAxis(StandardAxis.PrimaryX, false);
    bar2.DisplayOnAxis(xAxis2.AxisId, true);

    NAxis xAxis3 = ((NCartesianAxisCollection)chart.Axes).AddCustomAxis(AxisOrientation.Horizontal, AxisDockZone.FrontBottom);
    xAxis3.Visible = true;
    xAxis3.ScaleConfigurator.Title.Text = "Some Text";
    invisibleBars.DisplayOnAxis(StandardAxis.PrimaryX, false);
    invisibleBars.DisplayOnAxis(xAxis3.AxisId, true);

Hi Team,

Nice fix, Just one hiccup, If if try to fix the range of the xAxis1 in this code in decreasing order from 3 to 0 like this:

    xAxis1.View = new NRangeAxisView(new NRange1DD(3, 0), true, true);
Then there is no series displayed on this axis. Anyway to get it working?

Thank you

Hi Manal,
You need to specify that the axis scale is inverted - this is a property of the scale configurator:
chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator.Invert = true;
Hope this helps - let us know if you meet any problems.

Hi,

Just a update, I got it fixed by suing Scale.Invert = true;
