okay i just figure out how to do that.
first: my first code was wrong.i mean it should be like: chart_PrimUretimi.View.Margin = new System.Windows.Forms.Padding(1);

then i checked owerloads of this code.I just realised i can give different margins for every single sides.But when i use that one in form1.Designer.cs thats works only at first load.And it doesn't looks good when form size changed.I just wrote this codes in form1 sizechanged event and its worked well.I hope this helps someone else too.

private void form1_SizeChanged(object sender, EventArgs e)
        {
            this.chart_PrimUretimi.View.Margin = new System.Windows.Forms.Padding
                (
                (this.chart_PrimUretimi.Size.Width / 30) * -1,
                this.chart_PrimUretimi.Size.Height / 50,
                (this.chart_PrimUretimi.Size.Width / 30) * -1,
                (this.chart_PrimUretimi.Size.Height - 50) * -1
                );
        }

Hello, Kangroo, 

Thank you for writing.  

I am glad that you have found a suitable solution for your case. However, I would like to note that it may be appropriate to use RadRadialGauge with several arcs. In order to get familiar with the gauges you can refer to the following help articles:
https://docs.telerik.com/devtools/winforms/gauges/radialgauge/radialgauge
https://docs.telerik.com/devtools/winforms/gauges/radialgauge/structure
https://docs.telerik.com/devtools/winforms/gauges/radialgauge/understanding-gauge-elements/working-with-arcs

I hope this information helps. Should you have further questions I would be glad to help. 
 
 Regards,
Dess
