Hi,

You can increase the column width with:

<igCA:XamChart.Series>

                <igCA:Series ChartType="Column">

                    <igCA:Series.ChartParameters>

                        <igCA:ChartParameter Type="PointWidth" Value="2" />

                    </igCA:Series.ChartParameters>

                    <igCA:Series.DataPoints>

                        <igCA:DataPoint Value="5" />

                    </igCA:Series.DataPoints>

                </igCA:Series>

            </igCA:XamChart.Series>
