Hello.
I configure the chart axis so it has autoscale with absolute inflate:

NLinearScaleConfigurator linearConfigurator = new NLinearScaleConfigurator();
linearConfigurator.MajorTickMode = MajorTickMode.AutoMinDistance;
linearConfigurator.AutoMinorTicks = true;
linearConfigurator.ViewRangeInflateMode = ScaleViewRangeInflateMode.Absolute;
linearConfigurator.AbsoluteInflate = new NRange1DL(10, 10);
axis.ScaleConfigurator = linearConfigurator;

And I have the tools for data zooming:

_chartControl.Controller.Tools.Add(new NSelectorTool());
_chartControl.Controller.Tools.Add(new NAxisScrollTool());
_chartControl.Controller.Tools.Add(new NDataPanTool());
_chartControl.Controller.Tools.Add(new NDataZoomTool());

I met the problem that when the scrollbars are visible, absolute inflates seems to be zero (data points display close to chart bounds).

I have this problem only with Nevron version 2012. If I run the same code with the 2010 year version everything is correct (inflates persist).

Here is the full code that demonstrates the problem:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

InitChartControl();
}

private void InitChartControl()
{
_chartControl = new NChartControl();
this._chartControl.Dock = System.Windows.Forms.DockStyle.Fill;
this.Controls.Add(_chartControl);

_cartesianChart = (NCartesianChart)_chartControl.Charts[0];

NRangeSelection rangeSelection = new NRangeSelection();
rangeSelection.VerticalValueSnapper = new NAxisRulerClampSnapper();
rangeSelection.HorizontalValueSnapper = new NAxisRulerClampSnapper();
_cartesianChart.RangeSelections.Add(rangeSelection);

InitAxis(_cartesianChart.Axis(StandardAxis.PrimaryX));
InitAxis(_cartesianChart.Axis(StandardAxis.PrimaryY));

_chartControl.Controller.Tools.Add(new NSelectorTool());
_chartControl.Controller.Tools.Add(new NAxisScrollTool());
_chartControl.Controller.Tools.Add(new NDataPanTool());
_chartControl.Controller.Tools.Add(new NDataZoomTool());

generateData();

_chartControl.Refresh();
}

private void InitAxis(NAxis axis)
{
axis.ScrollBar.Visible = true;
axis.ScrollBar.ShowSliders = true;
axis.ScrollBar.ViewRangeChanged += new EventHandler(OnScrollBarViewRangeChanged);

axis.PagingView = new NNumericAxisPagingView();
axis.PagingView.ResetMode = PagingViewResetMode.View;

NLinearScaleConfigurator linearConfigurator = new NLinearScaleConfigurator();
linearConfigurator.MajorTickMode = MajorTickMode.AutoMinDistance;
linearConfigurator.AutoMinorTicks = true;
linearConfigurator.ViewRangeInflateMode = ScaleViewRangeInflateMode.Absolute;
linearConfigurator.AbsoluteInflate = new NRange1DL(10, 10);
axis.ScaleConfigurator = linearConfigurator;
}

private void OnScrollBarViewRangeChanged(object sender, EventArgs e)
{
_chartControl.Refresh();
}

private void generateData()
{
NLineSeries line = (NLineSeries)_cartesianChart.Series.Add(SeriesType.Line);
line.Name = "Line Series";
line.DataLabelStyle.Visible = false;
line.UseXValues = true;
line.FillStyle = new NColorFillStyle(Color.Black);

double measureXValue = 1;
double measureValue = 82;
int pointsNumber = 20;
for (int i = 0; i < pointsNumber; i++)
{
line.AddDataPoint(new NDataPoint(measureXValue, measureValue));
measureValue -= 4;
measureXValue += 3;
}
}

private NChartControl _chartControl;

private NCartesianChart _cartesianChart;
