Change labels on x-axis

[Lizabeth]

I have added a lot of data to a Points series through the Series.Add(double x, double y, string text, System.Drawing.Color color) method.

The labels and values on the x-axis then turns out to be the strings added. I do not want this! I want the labels and values on the x-axis to be the x-values added. How do I change the labels and values to be the x-values added instead of the strings?

I want the string values to be hidden. When clicking on a point in the series I want to be able to find out what the string value is for that particular point.

I also want to do the opposite - when I have a known string, I want to loop through all points to find out which one has the known string value and then set the color of that particular point.

How do I accomplish this?

You can try the ENum AxisLabelStyle, e.g.

Code: Select all

tChart1.Axes.Bottom.Labels.Style = Steema.TeeChart.AxisLabelStyle.Value;

Hi,

Thank you! I also wanted to know the following:

When clicking on a point in the series I want to be able to find out what the string value is for that particular point. What property or method do I use to accomplish this?

I also want to do the opposite - when I have a known string, I want to loop through all points to find out which one has the known string value and then set the color of that particular point.

Hi

Thank you! I also wanted to know the following:

When clicking on a point in the series I want to be able to find out what the string value is for that particular point. What property or method do I use to accomplish this?

I also want to do the opposite - when I have a known string, I want to loop through all points to find out which one has the known string value and then set the color of that particular point.

Try:

Code: Select all

		private void Form1_Load(object sender, System.EventArgs e) {
			Random rnd = new Random();
			char chr;

			for(int i=0; i<10;++i){
				chr = Convert.ToChar(65 + i);
				points1.Add((double)i, rnd.Next(100), chr.ToString(), Color.Red);
			}
			points1.XValues.Order = Steema.TeeChart.Styles.ValueListOrder.None;
			tChart1.Legend.Visible = false;
		}

		private void points1_Click(object sender, System.Windows.Forms.MouseEventArgs e) {
			int valueIndex = points1.Clicked(e.X, e.Y);
			double xVal, yVal;
			if(valueIndex!=-1) {
				label1.Text = points1[valueIndex].Label;
				//points1[valueIndex].Color = Color.Blue <- This does not work due to a bug
				//I have fixed this bug and this fix will be included in the next maintenance 
				//release. In the meantime you can do:
				xVal = points1[valueIndex].X;
				yVal = points1[valueIndex].Y;
				points1.Delete(valueIndex);
				points1.Add(xVal, yVal, label1.Text,Color.Blue);
			}
		}

Hi,

When does the next maintenance release come?
