我最近向 WinForm 添加了一些图表，并使用实时数据进行更新。我的表单加载喜欢这样：

private void MyForm_Load (object sender, EventArgs e){
...bunch of code
//Waveforms
InitializeChartEKG();
InitializeSpO2WaveformChart();
InitializeEtCO2WaveformChart();
FillWaveformCharts();
}

实时图表的创建方式如下：

public async void FillWaveformCharts() {
     waveformData = AnesthWaveformDatas.CreateWaveformObjects(anestheticRecordNum);
     Action action = () =>
     FillChartEKG(waveformData);
     Invoke(action);
     action = () =>
     FillChartSpO2(waveformData);
     Invoke(action);
     action = () =>
     FillChartEtCO2(waveformData);
     Invoke(action3);
}

然后，在每个 FillChart 方法中，我更新 UI，以便表单不会冻结：

public async void FillChartEKG (List<AnesthWaveformData> waveformData) {
 for (i = 0; i < waveformData.Count; i++){
   ...bunch of code that takes a long time to run...
  UpdateUI(); //updates UI …
