Question

我希望我的图表从0,0开始，但现在它从数据开始时开始（因为我不知道xdatamember的更好的替代方案是获得我想要的结果。任何建议？

        private void Form1_Load(object sender, EventArgs e)
        {
        dataAdapter = new SqlDataAdapter(strSQL, strCon);
        commandBuilder = new SqlCommandBuilder(dataAdapter);

        // Populate a new data table and bind it to the BindingSource.
        DataTable table = new DataTable();
        table.Locale = System.Globalization.CultureInfo.InvariantCulture;
        dataAdapter.Fill(table);
        bindingSource.DataSource = table;

        // Resize the DataGridView columns to fit the newly loaded content.
        dataGridView.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader);
        // you can make it grid readonly.
        dataGridView.ReadOnly = true;
        // finally bind the data to the grid
        dataGridView.DataSource = bindingSource;
        GraphPane myPane = height.GraphPane;

        // Create a new DataSourcePointList to handle the database connection
        DataSourcePointList dspl = new DataSourcePointList();

        // Specify the table as the data source
        dspl.DataSource = table;

        dspl.XDataMember = "age";
        dspl.YDataMember = "height";

        LineItem Curve1 = myPane.AddCurve("student 1", dspl, Color.pink, SymbolType.None);
        height.AxisChange();
        myPane.Chart.Fill = new Fill(Color.White, Color.LightGray, 45.0F);

        // set the title and axis labels
        myPane.Title.Text = "student heights";
        myPane.XAxis.Title.Text = "age";
        myPane.YAxis.Title.Text = "height";

        myPane.XAxis.Type = AxisType.Date;
    }

首先，我快速搜索了这类事情并找到了这个：Lock axis in ZedGraph

您可以将XAxis.Min和YAxis.Min设置为您想要显示为相应轴的最小值的值。我的测试中的代码看起来像这样：

//static ZedGraph.ZedGraphControl graph = new ZedGraph.ZedGraphControl();
ZedGraph.GraphPane pane = graph.GraphPane;
pane.XAxis.Scale.Min = 0.0;
graph.AxisChange();
graph.RestoreScale(pane);
graph.ZoomOut(pane);
