Axis.Automatic with a margin

Hi,
when I have Axis.Automatic = true and there are two lines assigned to this axis and the first runs at y=1 and the second at y=3 then my axis min will be 1 and my max will be 3. The problem is when my series are just straight lines they are not visible because they are exactly at the borders of the chart. So i would need some kind of margin so that the min/max of the axis is always some pixels more than the actual min/max.
How can I do this? Is there a build-in functionality for this?

Okay, I've found it!
Axis.MinimumOffset & Axis.MaximumOffset do the job perfectly.

Hello,
seems like I was too hasty. Axis.MinimumOffset & Axis.MaximumOffset work only when Axis.Automatic is set to false. That's a big problem as one of our customers needs automatic axis scaling. What can I do about this?

Hello ctusch,
I couldn't reproduce your problem using last version of TeeChart.Net and next code:
Code: Select all
public Form1()
{
InitializeComponent();
InitializeChart();
}
private Steema.TeeChart.Styles.Line line1, line2;
Steema.TeeChart.TChart tChart1;
Steema.TeeChart.ChartController ChartController;
private void InitializeChart()
{
this.tChart1 = new Steema.TeeChart.TChart();
this.ChartController = new Steema.TeeChart.ChartController();
this.Controls.Add(tChart1);
this.Controls.Add(ChartController);
this.tChart1.Left = 100;
this.tChart1.Top = 50;
ChartController.Chart = tChart1;
tChart1.Aspect.View3D = false;
line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
line2 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
Random rnd = new Random();
for (int i = 0; i < 10; i )
{
line1.Add(i, rnd.Next(10));
line2.Add(i, rnd.Next(10));
}
tChart1.Axes.Left.MinimumOffset = 50;
tChart1.Axes.Left.MaximumOffset = 70;
Please, check if previous code works as you want? If it doesn't work for you could you tell us which version of TeeChart.Net are you using.
Thanks,

It doesn't work here, it looks like this:

Hello ctusch,
Your problem is solved in last version of TeeChart.Net (version 4) and in it version works correctly. For version 3 there are a workaround using StartPosition and EndPosition:
Code: Select all
public Form1()
{
InitializeComponent();
InitializeChart();
}
private Steema.TeeChart.Styles.Line line1, line2;
Steema.TeeChart.ChartController ChartController;
private void InitializeChart()
{
this.tChart1 = new Steema.TeeChart.TChart();
this.ChartController = new Steema.TeeChart.ChartController();
this.Controls.Add(tChart1);
this.Controls.Add(ChartController);
this.tChart1.Left = 100;
this.tChart1.Top = 50;
ChartController.Chart = tChart1;
tChart1.Aspect.View3D = false;
line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
line2 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
Random rnd = new Random();
for (int i = 0; i < 10; i++)
{
line1.Add(i, rnd.Next(10));
line2.Add(i, rnd.Next(10));
}
tChart1.Axes.Left.StartPosition = 10;
tChart1.Axes.Left.EndPosition = 95;
}
Could you please, tell us if previous code is a good solution for you?
I hope will helps.
Thanks,
