DevExpress之ChartControl實(shí)現(xiàn)時(shí)間軸實(shí)例
本文實(shí)例講述了DevExpress采用ChartControl實(shí)現(xiàn)時(shí)間軸的方法，分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：
關(guān)鍵代碼如下：
using System.Data;
using System.Windows.Forms;
using DevExpress.XtraCharts;
namespace DevExpressChart
{
public partial class winDateTime : Form
{
public winDateTime()
{
InitializeComponent();
}
private void winDateTime_Load(object sender, EventArgs e)
{
BuilderDevChart();
}
private DataTable CreateChartData()
{
DataTable table = new DataTable("Table1");
table.Columns.Add("Date", typeof(DateTime));
table.Columns.Add("Value", typeof(Int32));
table.Rows.Add(new object[] { new DateTime(2014, 5, 21), 10 });
table.Rows.Add(new object[] { new DateTime(2014, 6, 22), 20 });
table.Rows.Add(new object[] { new DateTime(2014, 7, 23), 40 });
table.Rows.Add(new object[] { new DateTime(2014, 8, 24), 20 });
table.Rows.Add(new object[] { new DateTime(2014, 9, 25), 30 });
return table;
}
private void BuilderDevChart()
{
Series _lineSeries = new Series("利潤(rùn)", ViewType.Line);
_lineSeries.ArgumentScaleType = ScaleType.DateTime;
_lineSeries.ArgumentDataMember = "Date";
_lineSeries.ValueDataMembers[0] = "Value";
_lineSeries.DataSource = CreateChartData();
chartControl1.Series.Add(_lineSeries);
chartControl1.SetTimeAxisX(DateTimeMeasurementUnit.Month, DateTimeMeasurementUnit.Month, "yyyy-MM");
//---------------------------------------------------------------
//_lineSeries.ValueScaleType = ScaleType.DateTime;
//_lineSeries.ArgumentDataMember = "Value";
//_lineSeries.ValueDataMembers[0] = "Date";
//_lineSeries.DataSource = CreateChartData();
//chartControl1.Series.Add(_lineSeries);
//XYDiagram _diagram = (XYDiagram)chartControl1.Diagram;
//_diagram.AxisY.DateTimeMeasureUnit = DateTimeMeasurementUnit.Month;
//_diagram.AxisY.DateTimeGridAlignment = DateTimeMeasurementUnit.Month;
//_diagram.AxisY.DateTimeOptions.Format = DateTimeFormat.Custom;
//_diagram.AxisY.DateTimeOptions.FormatString = "MMMM";
}
}
