Hi All,

Does anyone know how NumericalScale.MajorStep works in Graph? I have a Graph with X and Y axis and each axis has a numerical scale with only MajorStep. The width and height of Graph are set to 250mm and 120mm respectively and my requirement is that each axis should always have MajorGridLines at every 5mm. Is there a way I can use MajorStep property for this purpose or is there any other way I can satisfy this requirement?

Thanks,
Mandar

Hi,

The step of the Major Gridlines is determined by the range of the scale and the data. Gridlines on each 5mm means there is a step that wide.

Yeah I understand that and I tried to set MajorStep on the scale to 5 but that didn't work. Following is the snippet of code I had to end up using. You can see that in the code I do numericalScale1.MajorStep = 15D and only then the MajorGridLines in the report are actually 5mm apart. So my question is why can't I just set numericalScale1.MajorStep = 5D in this case? The total width of my Graph(Report) is set to 250mm?

this.cartesianCoordinateSystem1.XAxis = this.graphAxis2;
this.cartesianCoordinateSystem1.YAxis = this.graphAxis1;
//
// graphAxis2
//
this.graphAxis2.MajorGridLineStyle.LineColor = System.Drawing.Color.LightGray;
this.graphAxis2.MajorGridLineStyle.LineStyle = Telerik.Reporting.Drawing.LineStyle.Dotted;
this.graphAxis2.MajorGridLineStyle.LineWidth = Telerik.Reporting.Drawing.Unit.Pixel(0.5D);
this.graphAxis2.MajorGridLineStyle.Visible = true;
this.graphAxis2.MajorTickMarkDisplayType = Telerik.Reporting.GraphAxisTickMarkDisplayType.None;
this.graphAxis2.MinorGridLineStyle.LineColor = System.Drawing.Color.LightGray;
this.graphAxis2.MinorGridLineStyle.LineStyle = Telerik.Reporting.Drawing.LineStyle.Dotted;
this.graphAxis2.MinorGridLineStyle.LineWidth = Telerik.Reporting.Drawing.Unit.Pixel(0.5D);
this.graphAxis2.MinorGridLineStyle.Visible = false;
this.graphAxis2.Name = "graphAxis2";
numericalScale1.MajorStep = 15D;

Here's the snippet of code that shows how I am setting MajorStep

this.cartesianCoordinateSystem1.XAxis = this.graphAxis2;
this.cartesianCoordinateSystem1.YAxis = this.graphAxis1;
//
// graphAxis2
//
this.graphAxis2.MajorGridLineStyle.LineColor = System.Drawing.Color.LightGray;
this.graphAxis2.MajorGridLineStyle.LineStyle = Telerik.Reporting.Drawing.LineStyle.Dotted;
this.graphAxis2.MajorGridLineStyle.LineWidth = Telerik.Reporting.Drawing.Unit.Pixel(0.5D);
this.graphAxis2.MajorGridLineStyle.Visible = true;
this.graphAxis2.MajorTickMarkDisplayType = Telerik.Reporting.GraphAxisTickMarkDisplayType.None;
this.graphAxis2.MinorGridLineStyle.LineColor = System.Drawing.Color.LightGray;
this.graphAxis2.MinorGridLineStyle.LineStyle = Telerik.Reporting.Drawing.LineStyle.Dotted;
this.graphAxis2.MinorGridLineStyle.LineWidth = Telerik.Reporting.Drawing.Unit.Pixel(0.5D);
this.graphAxis2.MinorGridLineStyle.Visible = false;
this.graphAxis2.Name = "graphAxis2";
numericalScale1.MajorStep = 15D;
this.graphAxis2.Scale = numericalScale1;
this.graphAxis2.Style.Color = System.Drawing.Color.Black;
this.graphAxis2.Style.Visible = false;
this.graphAxis2.TitlePlacement = Telerik.Reporting.GraphAxisTitlePlacement.None;
//
// graphAxis1
//
this.graphAxis1.MajorGridLineStyle.LineColor = System.Drawing.Color.LightGray;
this.graphAxis1.MajorGridLineStyle.LineStyle = Telerik.Reporting.Drawing.LineStyle.Dotted;
this.graphAxis1.MajorGridLineStyle.LineWidth = Telerik.Reporting.Drawing.Unit.Pixel(0.5D);
this.graphAxis1.MajorGridLineStyle.Visible = true;
this.graphAxis1.MajorTickMarkDisplayType = Telerik.Reporting.GraphAxisTickMarkDisplayType.None;
this.graphAxis1.MinorGridLineStyle.LineColor = System.Drawing.Color.LightGray;
this.graphAxis1.MinorGridLineStyle.LineStyle = Telerik.Reporting.Drawing.LineStyle.Dotted;
this.graphAxis1.MinorGridLineStyle.LineWidth = Telerik.Reporting.Drawing.Unit.Pixel(0.5D);
this.graphAxis1.MinorGridLineStyle.Visible = false;
this.graphAxis1.Name = "graphAxis1";
numericalScale2.MajorStep = 19D;
this.graphAxis1.Scale = numericalScale2;
this.graphAxis1.Style.Visible = false;
this.graphAxis1.TitlePlacement = Telerik.Reporting.GraphAxisTitlePlacement.None;

Hi Mandar,

I think it is not possible to set the MajorStep to 5 mm, since it is dependent on your data. The MajorStep actually defines the step/interval for the major ticks/grid lines. It is not a static width of the space between two ticks/gridlines, since the ticks are based on the data coming from the data source.
