"data" - Curve

Data for the bar trend in the curve display mode.

Synopsis

setValue(string shape, "data", dyn_float DataX, dyn_float DataY);

getValue(string shape, "data", dyn_float &DataX, dyn_float &DataY);

shape.data(dyn_float DataX, dyn_float DataY);

Parameters

Parameter Description
shape Name of the object
DataX X values
DataY Y values

Description

This attribute specifies the data for the curve whereby the coordinates of the individual points are specified in the dyn_float arrays DataX (x-coordinates) and DataY (y-coordinates).

Example 

 main()
{
  shape bt=getShape("BAR_TREND1");
  dyn_float dx, dy;
  // Points for the curve
  dx=makeDynFloat(0,5,10,15,20,25,30,35,40);
  dy=makeDynFloat(0,30,0,40,0,50,0,60,0);
  // Setting the values
  setValue(bt, "data", dx, dy);
  // Linear curve
  bt.connection=BAR_LINEAR;
  // Fill the area
  bt.fill=TRUE;
  //Line color
  bt.lineColor("blue");
  // Update bar trend
  bt.flush();
}

You can set the line type via the attribute "lineType"

 bt.lineType("[dashed,oneColor,JoinMiter,CapButt,2]");
