C＃Chart与列之间的空格和字体大小Y轴的问题

Question

我正在努力（我是C＃的初学者）：1在列之间放置一些空格，定义Y轴的大小并在标签中显示辅助。我发布了我的代码，任何帮助都非常感谢。

        Overall.SelectCommand = ToChart1;
        Overall.Fill(ds, "TblChart1");
        chart1.DataSource = ds.Tables["TblChart1"];
        chart1.Series.Add("Series2");
        chart1.Series.Add("Series3");
        //chart1.Series["Series1"].XValueMember = "Ancillary";
        chart1.Series["Series1"].YValueMembers = "Ancillary";
        //chart1.Series["Series2"].XValueMember = "NonCommodity";
        chart1.Series["Series2"].YValueMembers = "NonCommodity";
        //chart1.Series["Series3"].XValueMember = "Totale";
        chart1.Series["Series3"].YValueMembers = "Totale";
        chart1.DataBind();
        chart1.ChartAreas[0].AxisX.LabelStyle.Font = new Font("Calibri", 5);
        chart1.ChartAreas[0].AxisX.Interval = 1;
        //chart1.ChartAreas[0].AxisY.Maximum = 800000;
        chart1.ChartAreas[0].AxisY.Minimum = 0;
        chart1.Series[0].LegendText = "Ancillary";
        chart1.Series[1].LegendText = "NonCommodity";
        chart1.Series[2].LegendText = "Total";
