Hello good day, i am trying draw line in the windows chart with the class CCanvas, want connect two points for one line, how follow:


CCanvas        miLineaUp;

atrhighVal[2]=maVal[2]+atrVal[2]*2.5;   // EMA(21) + ATR(14)*2.5

atrhighVal[1]=maVal[1]+atrVal[1]*2.5;   // EMA(21) + ATR(14)*2.5

y1=atrhighVal[2];    //previous value

y2=atrhighVal[1];   //actual value

miLineaUp.Line(x1, y1, x2, y2, clrAzure);
