Hi bakidost,

I'm not really sure that I understand what exactly You need but if you need to keep drawn chart not resizable I beleive the snippet below will help you. Firstly, You should set each axis' Extent property. Note that Extent property will take an effect only if current axis is visibe. But You may not need to have all axises displayed. That is why You should set the LineColor property of the axis to Color.Transparent. After setuping this You need to handle Resize event of the control in order to be able to reset axises' Extent property.

Public Cass MyForm

    ' drawn chart width
    Dim chartWidth As Integer
    ' drawn chart height
    Dim chartHeight As Integer
    Dim intialExtend As Integer = 200

    Private Sub MarginsOn3DBarChartForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        UltraChart1.Axis.Y.Extent = intialExtend
        UltraChart1.Axis.X.Extent = intialExtend
        UltraChart1.Axis.Y2.Visible = True
        UltraChart1.Axis.Y2.LineColor = Color.Transparent
        UltraChart1.Axis.Y2.Extent = intialExtend
        UltraChart1.Axis.X2.Visible = True
        UltraChart1.Axis.X2.LineColor = Color.Transparent
        UltraChart1.Axis.X2.Extent = intialExtend
        chartWidth = UltraChart1.Width - intialExtend * 2
        chartHeight = UltraChart1.Height - intialExtend * 2
    End Sub

    Private Sub UltraChart1_Resize(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UltraChart1.Resize

        Dim currentYExtent As Integer = (UltraChart1.Width - chartWidth) / 2
        Dim currentXExtent As Integer = (UltraChart1.Height - chartHeight) / 2

        If currentYExtent > 0 Then
            UltraChart1.Axis.Y.Extent = currentYExtent
            UltraChart1.Axis.Y2.Extent = currentYExtent
        End If

        If currentXExtent > 0 Then
            UltraChart1.Axis.X.Extent = currentXExtent
            UltraChart1.Axis.X2.Extent = currentXExtent
        End If

    End Sub
