我正在silverlight 中创建RadBarChart。
如果我在同一个类中硬编码Yvalue
和XCategory
值,则图表显示正确的数据。
下面是我Initializecomponent()
在 Sample.cs 类中的方法之后调用的方法。
public void FillSampleChartData()
{
DataSeries dataSeries = new DataSeries();
dataSeries.Definition = new BarSeriesDefinition();
dataSeries.Add(new DataPoint() { YValue = 1127.13, XCategory = "Victor" });
dataSeries.Add(new DataPoint() { YValue = 1123.80, XCategory = "Kishore" });
dataSeries.Add(new DataPoint() { YValue = 9948.94, XCategory = "Vincent" });
RadChartSales.DefaultView.ChartArea.DataSeries.Add(dataSeries);
}
我怀疑我是否从其他类调用相同的方法...条形图未显示任何数据。让我知道为什么图表不显示数据。
//This is my original method
public void FillSampleChartData(IList collection)
{
int listcount = collection.Count;
int count = -1;
double[] myArray1 = new double[listcount];
string[] myArray2 = new string[listcount];
foreach (BizFramework.Web.Model.SalesBySalesPersonSummary_Result dtvws in collection)
{
count++;
myArray1[count] = Convert.ToDouble(dtvws.Amount);
myArray2[count] = dtvws.Salesperson;
}
DataSeries dataSeries = new DataSeries();
dataSeries.Definition = new BarSeriesDefinition();
if (myArray1.Count() > 0)
{
for (int i = 0; i < myArray1.Count(); i++)
{
dataSeries.Add(new DataPoint() { YValue = myArray1[i], XCategory = myArray2[i] });
}
RadChartSales.DefaultView.ChartArea.DataSeries.Add(dataSeries);
}
}
