내가 링크 Adding text , image to asp.net chart control 를 사용하여 시도하지만 라벨이 표시되지 않을 수 있습니다. 또한 x를 0,120,130, ... , y 축을 0,20,30 으로 시작 하시겠습니까? 어떤 도움이 appericiated

Answer 1

당신은 먼저 datapoint를 생성하고 시리즈에 추가해야합니다. 예 :

DataPoint dp = new DataPoint(); 
dp4.Font = dp_font; 
dp4.XValue = 185; 
dp4.SetValueY(90); 
dp4.Label = "Label text"; 

Series["bmi30"].Points.Add(dp)
