Cylinder

A cylinder with a label.

SVG selectors​

Supported attrs properties:

SelectorNodeDescription
rootSVGGElementContainer of all nodes
bodySVGPathElementLateral area of the cylinder. _The shape has a custom attribute lateralArea set to 10 by default. The attribute sets the SVGPathElement's d in the shape of the lateral area of a tilted cylinder. The attribute expects a topRy value; either a percentage or a number. The value determines the vertical radius of the exposed area of cylinder base; either relative to shape height, or directly. (Refer to the cylinder.topRy() function for more detailed specification.)
topSVGEllipseElementTop of the cylinder (cylinder base)
labelSVGTextElementText inside the body
const cylinder = new standard.Cylinder();
cylinder.resize(100, 200);
cylinder.position(525, 75);
cylinder.attr('root/title', 'shapes.standard.Cylinder');
cylinder.attr('body/fill', 'lightgray');
cylinder.attr('top/fill', 'gray');
cylinder.attr('label/text', 'Cylinder');
cylinder.topRy('10%');

Methods​

topRy()​

cylinder.topRy(t?: string | number, opt?: dia.ModelSetOptions): string | number;

If used without parameters, returns the vertical radius of the exposed area of the cylinder base (the value of the body/lateralArea attribute; 10 by default).

If first parameter is not undefined, sets the cylinder vertical radius of the exposed area of the cylinder base.

If the provided value is a percentage, it is relative to the refBBox.height of the shape. In practice, only values between '0%' and '50%' make sense. If the provided value is a number, it determines the vertical radius directly. Only values between 0 and half of refBBox.height make sense.

The function automatically sets the value of several attributes: body/lateralArea; and top/ry, top/cy, top/refRy and top/refCy. If these arguments need to be modified further, make sure to assign them only after calling cylinder.topRy.
