How to add dynamically more line series into a line chart in wpf toolkit?
提问by SH.IN
I'm trying to use wpf toolkit chart line and I need to have more then one line in the chart but i cant figer out how to do that I tried to look in here and Google but I always found an XAML code and I need to do it dynamically in c#. In the program I cant know how much charts i will need and how many line in every chart this is way I can't do it in the XAML...
我正在尝试使用 wpf 工具包图表线，我需要在图表中有不止一条线，但我无法弄清楚如何做到这一点，我试图在此处和谷歌中查看，但我总是找到一个 XAML 代码，我需要在 C# 中动态执行。在程序中，我不知道我需要多少图表以及每个图表中有多少条线，这是我无法在 XAML 中做到的方式......
for (int j = 0; j < 4; j++) //its just so i cant check it
{
ColumnDefinition cd = new ColumnDefinition();
myGrid.ColumnDefinitions.Add(cd);
Chart chart1 = new Chart();
LineSeries lineChart = new LineSeries();
chart1.Height = 200;
chart1.Width = 300;
chart1.Title = (j);
//((LineSeries)chart1.Series[0]).ItemsSource = valueList;
lineChart.DependentValuePath = "Value";
lineChart.IndependentValuePath = "Key";
lineChart.ItemsSource = valueList;
lineChart.IsSelectionEnabled = true;
chart1.Series.Add(lineChart);
lineChart.ItemsSource = valueList1;
chart1.Series.Add(lineChart); <---
myGrid.Children.Add(chart1);
Grid.SetColumn(chart1, (j));
Grid.SetRow(chart1, 0);
}
I tried this but it is not working ...
我试过这个，但它不起作用......

XAML:
XAML：
<chartingToolkit:Chart Name="lineChart" />
<chartingToolkit:Chart Name="lineChart" />
Code-behind:
代码隐藏：
private void showChart(List<KeyValuePair<string, int>> valueList)
{
LineSeries lineSeries1 = new LineSeries();
lineSeries1.Title = "Title";
lineSeries1.DependentValuePath = "Value";
lineSeries1.IndependentValuePath = "Key";
lineSeries1.ItemsSource = valueList;
lineChart.Series.Add(lineSeries1);
}
Where you can define valueList as:
List<KeyValuePair<string, int>> valueList = new List<KeyValuePair<string, int>>();
您可以将 valueList 定义为：
List<KeyValuePair<string, int>> valueList = new List<KeyValuePair<string, int>>();
and insert the desired values as valueList.Insert(0, new KeyValuePair<string, int>(key, value));
并插入所需的值作为 valueList.Insert(0, new KeyValuePair<string, int>(key, value));
