Problems about SizeValues!

[Jackey]

hi,
i have trouble at change the code from delphi to .net(c#);
the formal code (using TeeChart Pro 7) is:

Code: Select all

dbchart1.Series[s1-cgjl_num+j].AddXY(barwid,sd[i]);
 (dbchart1.Series[s1-cgjl_num+j] as TBarSizeSeries).SizeValues[rslt[j]]:=(ed[i]-sd[i]);

i must translate it into c#(TeeChart for .NET v2 Evaluation):

Code: Select all

WebChart1.Chart.Series[s1-cgjl_num+j].Add(barwid,sd[i]);

(WebChart1.Chart.Series[s1-cgjl_num+j]as Steema.TeeChart.Styles.HorizBar).???);

how to express the ???. or how can i get the result with c#?

Best Regards.

Hi Jackey,

TBarSizeSeries is a custom series type, isn't it? Thus SizeValues method doesn't exist for other series types. If you are trying to retrieve the horizontal line series values you may use:

Code: Select all

(WebChart1.Chart.Series[s1-cgjl_num+j]as Steema.TeeChart.Styles.HorizBar).XValues.Value[ed[i]-sd[i]];
(WebChart1.Chart.Series[s1-cgjl_num+j]as Steema.TeeChart.Styles.HorizBar)..YValues.Value[ed[i]-sd[i]];

Otherwise, could you please explain what SizeValues method does?

[Jackey]

my code is that ,

Code: Select all

this.WebChart1.Chart.Legend.Top=-320;
this.WebChart1.Chart.Legend.VertSpacing=20;

you can run it ,then you can see:



but i want to get the result like below,which use delphi

[Jackey]

i want my HorizBar has the same value ,but diffent size, how can i do get it.

Hi Jackey,

Then I'd suggest you to create your custom series style inheriting from Steema.TeeChart.Styles.HorizBar and overriding its DrawValue method as shown below. To draw different BarStyles you will have to extend the DrawBar method implementing the drawing of the different shapes in TChart's canvas.

Code: Select all

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using Steema.TeeChart.Drawing;
using Steema.TeeChart.Styles;

namespace HorizBarWidth
{
	/// <summary>
	/// Summary description for WebForm1.
	/// </summary>
	public class WebForm1 : System.Web.UI.Page
	{
		protected Steema.TeeChart.Web.WebChart WebChart1;
	
		private void Page_Load(object sender, System.EventArgs e)
		{	
			MyHorizBar HorizBarWidth = new MyHorizBar(WebChart1.Chart);
			HorizBarWidth.FillSampleValues();

			HorizBarWidth.ColorEach=true;
		}

		#region Web Form Designer generated code
		override protected void OnInit(EventArgs e)
		{
			//
			// CODEGEN: This call is required by the ASP.NET Web Form Designer.
			//
			InitializeComponent();
			base.OnInit(e);
		}
		
		/// <summary>
		/// Required method for Designer support - do not modify
		/// the contents of this method with the code editor.
		/// </summary>
		private void InitializeComponent()
		{    
			this.Load += new System.EventHandler(this.Page_Load);

		}
		#endregion

	}

	public class MyHorizBar : HorizBar 
	{

		private Steema.TeeChart.Chart chart;

		public MyHorizBar(Steema.TeeChart.Chart Chart) : base(Chart)
		{
			chart = Chart;

			Pen.Visible=false;
			Marks.Visible=false;
		}

		public override void DrawValue(int valueIndex)
		{
			base.DrawValue (valueIndex);			
			NormalBarColor=ValueColor(valueIndex);

			Rectangle r=new Rectangle(0,0,0,0);

			if ( NormalBarColor != Color.Empty )
				r.Y=CalcYPos(valueIndex);

			double Percent = XValues.Value[valueIndex] / MaxXValue();
			if (valueIndex>0)
				r.Height=Convert.ToInt16( (CalcYPos(valueIndex-1)-r.Y) * Percent );
			else
				r.Height=Convert.ToInt16( (r.Y-CalcYPos(1)) * Percent );

			r.X=GetOriginPos(valueIndex);
			System.Drawing.Rectangle Rect=chart.ChartRect;
			r.Width=Rect.Width;

			if ( Pen.Visible && !chart.Aspect.View3D) // CDI changed
				r.Height++;

			iBarBounds=r;

			if (r.Right>r.X) 
				DrawBar(valueIndex,r.X,r.Right);
			else 
				DrawBar(valueIndex,r.Right,r.X);
		}

		private void DrawBar(int barIndex,int startPos,int endPos) 
		{
			Graphics3D g=chart.Graphics3D;

			SetPenBrushBar(NormalBarColor);
			Rectangle r=iBarBounds;

			int tmpMidY=(r.Y+r.Bottom) / 2;
			BarStyles tmp=DoGetBarStyle(barIndex);
			if ( chart.Aspect.View3D )
				switch (tmp) 
				{
					case BarStyles.Rectangle:  g.Cube(startPos,tmpMidY,endPos,r.Bottom,StartZ,EndZ,bDark3D); break;
				}
			else 
			{
				switch (tmp) 
				{
					case BarStyles.Rectangle:   BarRectangle(NormalBarColor,iBarBounds); break;
				}
			}
			DrawTickLines(startPos,endPos,tmp);
		}	

	}
