"yOrigin"

setValue (string shape, "yOrigin", int orig);

getValue (string shape, "yOrigin", int &orig);

shape.yOrigin (int orig);

The origin of the y-scale on the y-axis can be specified or read with this attribute. Possible values that are defined using constants are: bottom (BAR_BOTTOM), top (BAR_TOP) or in the centre (BAR_CENTER).

Example

In this example, the Y-axis is scaled as follows: The scale starts at the bottom end ("yOrigin") with the value 0 ("yCenter") and ends with the value 100 ("yRange"). The range is divided into steps of 10 ("yStep") with one decimal place ("yPrec") without grid ("yGrid").

main()

{

  shape bt=getShape("BarTrend1");

  bt.yOrigin=BAR_BOTTOM;

  bt.yCenter=0;

  bt.yRange=100;

  bt.yStep=10;

  bt.yPrec=1;

  bt.yGrid=FALSE;

  bt.flush(); // Update bar trend

}
