Custom Vertical Axis changes .Minimum when FastLine.Add(X,Y)

[tirby]

Hi,

I'm having no luck solving this by myself, I'm hoping someone can help!

The problem occurs after setting up the grid and setting scaling of the custom Vertical axis 0 to 100.

Then using a pushbutton- FastL(0).Add(111458, 30.2);

Some code fragments I'm using:

Code: Select all

public static Steema.TeeChart.Styles.FastLine[] FastL = new Steema.TeeChart.Styles.FastLine[128];

FastL[Index] = new Steema.TeeChart.Styles.FastLine(tChart1.Chart);

I have a small test project to demonstrate the problem that I can upload for reference.

Thanks!

Hello Tirby,

Using last version Build 4.1.2012.09283 and next code the mínim custom vertical axis isn't change for me:

Code: Select all

   public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }
        Steema.TeeChart.Axis axis1;
        Random rnd = new Random();
        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            //Custom Vertical Axis
            axis1 = new Steema.TeeChart.Axis(tChart1.Chart);
            tChart1.Axes.Custom.Add(axis1);
            axis1.Horizontal = false;
            axis1.StartPosition = 0;
            axis1.EndPosition = 48;
            axis1.AxisPen.Color = Color.Red;
            axis1.SetMinMax(0, 100);
            //Left Axis. 
            tChart1.Axes.Left.StartPosition = 50;
            tChart1.Axes.Left.EndPosition = 100;
            tChart1.Axes.Left.SetMinMax(0, 100);

            for (int i = 0; i < 128; i++)
            {
                new FastLine(tChart1.Chart);
                for (int j = 100000; j < 111458; j = j + 100)
                {
                    tChart1[i].Add(j, rnd.Next(100));
                }
                if (i % 2 == 0)
                {
                    tChart1[i].CustomVertAxis = axis1;
                }
                else
                {
                    tChart1[i].VertAxis = VerticalAxis.Left;
                }
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
           
               tChart1[0].Add(111458, 30.2);
          
        }

Could you tell us if previous code works for you? If previous code doesn't behave as you want, please could you send us your project because we can reproduce your problem and try to suggest you a good solution for you.

Thanks,

Sandra,

Thanks for looking at this, I'll try the code.

The version I'm running is the latest available from the Customer Download section.
My version is 3.5.3700.30575

Sandra,

Using your example, I was able to modify my program and correct the problem.
I think it was probably the way I was doing things.

Thanks for getting me on the right track!
