使用DEV的图标控件CharControl,代码如下:
try { //声明折线 XYDiagram Diagram = chartControl1.Diagram as XYDiagram; Diagram.AxisX.GridSpacingAuto = false; Diagram.AxisX.DateTimeScaleOptions.MeasureUnit = DateTimeMeasureUnit.Minute;//这个可以根据你自己的情况设置 Diagram.AxisX.DateTimeScaleOptions.GridAlignment = DateTimeGridAlignment.Minute; //这个是间隔单位 //Diagram.AxisX.GridSpacing = 60; // 每60秒为一个间隔。 Diagram.AxisX.Label.DateTimeOptions.Format = DateTimeFormat.Custom; Diagram.AxisX.Label.DateTimeOptions.FormatString = "MM-dd HH:mm"; Diagram.AxisX.Range.Auto = false; //要开启滚动条必须将其设置为false //X轴开始时间 DateTime XbeginTime = new DateTime(); //X轴结束时间 DateTime XendTime = new DateTime(); if (this.lueDeviceSN.EditValue.ToString() == "%") { } else { DataTable dt = InfoService.GetRealTimeView(StaticInfo.enterpriseID , this.lueDeviceSN.EditValue.ToString()); if (dt != null) { if (dt.Rows.Count > 0) { XendTime = ConvertHelper.TryToDatetime(dt.Rows[0]["UpdateTime"].ToString().Replace(":", ":")); XbeginTime = ConvertHelper.TryToDatetime(dt.Rows[dt.Rows.Count - 1]["UpdateTime"].ToString().Replace(":", ":")); this.chartControl1.Series[0].ArgumentScaleType = ScaleType.DateTime; this.chartControl1.Series[0].ArgumentDataMember = "UpdateTime"; this.chartControl1.Series[0].ValueDataMembers[0] = "Temperature"; this.chartControl1.Series[0].Name = this.lueDeviceSN.EditValue.ToString(); this.chartControl1.Series[0].Points.BeginUpdate(); this.chartControl1.Series[0].Points.Clear(); for (int j = 0; j < dt.Rows.Count; j++) { this.chartControl1.Series[0].Points.Add( new SeriesPoint(ConvertHelper.TryToDatetime(dt.Rows[j]["UpdateTime"].ToString().Replace(":", ":")) , ConvertHelper.TryToDouble(dt.Rows[j]["Temperature"]))); } this.chartControl1.Series[0].Points.EndUpdate(); } } } if (XbeginTime == XendTime) { XbeginTime = DateTime.Now; XendTime = XbeginTime.AddMinutes(20); } Diagram.AxisX.Range.MaxValue = XendTime; Diagram.AxisX.Range.MinValue = XbeginTime; Diagram.AxisX.Title.Text = "时间"; Diagram.AxisY.Range.MinValue = -5; Diagram.AxisY.Range.MaxValue = 40; Diagram.AxisY.Title.Text = "温度值"; } catch (Exception ex) { }
由于时间是通过JSON传输解析的,发生了中文:的问题。
