我有两个问题:
我想要数据表中的名字,但它以数字形式显示我。
我想在两个酒吧之间留一个差距,但我找不到办法。
以下是代码:
private void InitializeGraph(DataTable poDt) { Telerik.Charting.ChartSeries chartseries = new Telerik.Charting.ChartSeries();
try
{
chartseries.Type = Telerik.Charting.ChartSeriesType.Bar;
Telerik.Charting.ChartSeriesItem csItem;
RadChart1.PlotArea.XAxis.AutoScale = true;
RadChart1.PlotArea.XAxis.DataLabelsColumn = "Name";
for (int iRow = 0; iRow < poDt.Rows.Count; iRow++)
{
chartseries = new Telerik.Charting.ChartSeries();
chartseries.Type = Telerik.Charting.ChartSeriesType.Bar;
chartseries.Name = poDt.Rows[iRow]["Name"].ToString().Trim();
csItem = new Telerik.Charting.ChartSeriesItem();
csItem.Name = poDt.Rows[iRow]["Name"].ToString();
csItem.Label.TextBlock.Text = poDt.Rows[iRow]["Value"].ToString();
RadChart1.PlotArea.XAxis.Appearance.TextAppearance.AutoTextWrap = Telerik.Charting.Styles.AutoTextWrap.True;
csItem.YValue = Int32.Parse(poDt.Rows[iRow]["Value"].ToString());
chartseries.AddItem(csItem);
RadChart1.Series.Add(chartseries);
}
RadChart1.PlotArea.XAxis.AddRange(1, poDt.Rows.Count, 1);
RadChart1.PlotArea.XAxis[poDt.Rows.Count].TextBlock.Text = chartseries.Name;
poDt.Rows.Count.ToString();
RadChart1.PlotArea.XAxis.AutoShrink = false;
RadChart1.PlotArea.XAxis.AutoShrink = true;
RadChart1.Series.Add(chartseries);
RadChart1.PlotArea.Appearance.Border.Visible = false;
RadChart1.Appearance.Border.Visible = true;
RadChart1.PlotArea.YAxis.IsLogarithmic = true;
RadChart1.PlotArea.YAxis.AutoScale = true;
RadChart1.PlotArea.YAxis.Appearance.ValueFormat=Telerik.Charting.Styles.ChartValueFormat.Number;
RadChart1.Appearance.BarWidthPercent = 50;
RadChart1.Chart.Appearance.FillStyle.MainColor = System.Drawing.Color.Red;
RadChart1.Chart.Appearance.FillStyle.MainColor = System.Drawing.Color.Transparent;
RadChart1.Legend.Appearance.FillStyle.MainColor = System.Drawing.Color.Transparent;
}
catch (Exception Ex)
{
//throw;
}
finally
{
poDt.Clear();
poDt = null;
chartseries = null;
}
}

抱歉,我不相信有办法同时显示两个X轴。
我的建议是您为X轴使用CategoricalAxis并创建一个自定义条形图,其中包含区分这两个值的图例。我没有任何工作样本,但您可以将这个Telerik Silverlight演示用于初学者。
此外,如果可以,请切换到RadChartView。因为我会建议一种更简单的方法,即使用分类X轴并创建多个Y轴。如果你走这条路线,你可以为具有多个Y轴的DateTimeContinuous(或Categorical)X轴做这样的事情:
int count = 0;
LineSeries lineSeries = new LineSeries();
lineSeries.CategoryBinding = new PropertyNameDataPointBinding() { PropertyName = "TimeStamp" };
lineSeries.ValueBinding = new PropertyNameDataPointBinding() { PropertyName = "Value" };
lineSeries.VerticalAxis = new LinearAxis()
{
Title = "Title Here"
};
lineSeries.ItemsSource = yourCollection.Values;
//First Y-axis to be placed on the left of X-axis,
//additional Y-axes to be placed on right
if (count > 0 )
{
lineSeries.VerticalAxis.HorizontalLocation = Telerik.Charting.AxisHorizontalLocation.Right;
}
count++;
chartName.Series.Add(lineSeries);
希望这有帮助。
