Question

我创建了条形图但该系列正在显示垂直。我需要显示水平 .i使用下面的代码

private void LoadChartData(DataTable initialDataSource) { for (int i = 1; i < initialDataSource.Columns.Count; i++) { Series series = new Series(); foreach (DataRow dr in initialDataSource.Rows) { int y = (int)dr[i]; series.Points.AddXY(dr["Closing_Month"].ToString(), y); } Chart1.Series.Add(series); } }

Answer 1

您可以在Series变量中定义图表类型。

/*Horizontal bars*/
series.ChartType = SeriesChartType.Bar;

/*Vertical columns*/
series.ChartType = SeriesChartType.Column;

所以你的代码看起来像这样：

private void LoadChartData(DataTable initialDataSource)
{
    for (int i = 1; i < initialDataSource.Columns.Count; i++)
    {
        Series series = new Series();
        /*make sure every series is of the same chart type*/
        foreach (Series series in chart.Series)
        {
            series.ChartType = SeriesChartType.Bar;
        }
        foreach (DataRow dr in initialDataSource.Rows)
        {
            int y = (int)dr[i];
            series.Points.AddXY(dr["Closing_Month"].ToString(), y);
        }
        Chart1.Series.Add(series);
    }
}
