一.前言       本月正好做一些关于工程4D,5D的界面展示,正好要用到Dev控件中的ChartControl控件,也就是图表控件. 折腾了两星期完成了一个比较能说的过去的界面吧.(领导要求高,可能不是这么想的吧,哈哈) 二.ChartControl的UI解读 <dxc:ChartControl Name="> <dxc:ChartControl.Legend> <dxc:Legend Orientation=" /> </dxc:Char

第三方控件,设置ChartControl的样式,仅供参考 Demo: <Grid> <Grid.Resources> <SolidColorBrush x:Key="GridLineBursh" Color="CornflowerBlue"></SolidColorBrush> </Grid.Resources> <dxc:ChartControl Background="Transpare

WPF常用的第三方控件集,DevExpress 下面介绍如何生成Chart界面: <dxc:ChartControl AnimationMode="OnDataChanged" Background="Transparent" BorderThickness="0" BorderBrush="Transparent" SelectionMode="Single" SeriesSelectionMode

private void BindChartControl(DataTable dataTable,ChartControl chartControl,int[] columnNO,ViewType viewType) { chartControl.Series.Clear(); int num = columnNO.Length; List<Series> series=new List<Series>(); ; i < num; i++) { Series singleS

添加折线图(柱状图) 拖动ChartControl到Form上 在Series Collection中添加Line(或Bar) DevExpress.XtraCharts.Series series1 = new DevExpress.XtraCharts.Series(); DevExpress.XtraCharts.LineSeriesView lineSeriesView1 = new DevExpress.XtraCharts.LineSeriesView(); series1.View

col=ifelse(x<0, "blue", "red") #如果x值为负值,用蓝色表示,反之,用红色表示 abline(v=0,col="grey",lwd=2,lty=6) #用灰色画出垂直线x=0,如果将v=0用h=0代替,表示画水平线y=0 效果图如下:

DevExpress ChartControl加载大数据量数据时的性能优化方法有哪些? 关于图表优化,可从以下几个方面解决: 1.关闭不需要的可视化的元素(如LineMarkers, Labels等): Series.View.LineMarkerOptions.Visible =false. 2. 关闭图表的滚动与缩放功能,手动调整范围,这样将大大减少所需计算的个数. 3. 将 ChartControl.RefreshDataOnRepaint属性设为false 4. 将 ChartContr

<dxc:ChartControl Name="chartControl1">            <dxc:ChartControl.Diagram>                <dxc:XYDiagram2D>                    <dxc:XYDiagram2D.Series>                        <dxc:LineSeries2D DisplayName="Firs

什么是垂直分割线 垂直(或条形图中的水平)分隔线是用来帮助用户分隔数据块的.可以被放置在任何两个数据点,即使是不规则的间隔也可以. <chart caption='Monthly Revenue' xAxisName='Month' yAxisName='Revenue' numberPrefix='$' showValues='0'> <set label='Oct' value='420000' /> <set label='Nov' value='910000' /&g

最近因为公司项目需要用到WinForm的DecExpress控件,在这里把一些使用方法总结一下. DevExpress中有一个专门用来绘制图表的插件ChartControl,可以绘制折线图.饼状图.柱状图等图表. 1.绘制图表基本步骤 准备数据并绑定 这里从数据库中取得数据,可以根据自己的需要修改. 1 DataTable dtData = BF<bll_ep_collection_data>.Instance.GetDataTable(sqlwhere, "data_time&qu

winform开发,用devexpress中的gridcontrol控件,头部默认是3D样式,当客户希望像内容一样扁平化显示且需要添加垂直线(右边框)时恶梦开始了..经过一阵摸索发现可以这样解决: 1.设置GridControl的GridView控件的PaintStyleName属性为Web 2.为GridControl的GridView控件添加CustomDrawColumnHeader事件,参考代码如下: private void gridView1_CustomDrawColumnHead

由于工作需要,最近学习了DevExpress控件中的ChartControl,并做了简单尝试,通过程序动态添加数据源到chartControl控件中,绘制了如下的条形图. 条形图的颜色等外观可在chartControl控件的RunWizard中编辑,也可以在RunWizard中添加静态的Series,并对条形图的各种属性进行设置. using System; using System.Collections.Generic;using System.ComponentModel;using Sy
