Can't reshape circular Shape

thanks for your response. I am dragged circle shape in the diagram area and trying to resize the shape horizontal or vertically . but it won’t be stretch vertically and horizontally. other shapes are re-sizing properly .please find the code.

    function nodeStyle() {
        return [

          new go.Binding("location", "loc", go.Point.parse).makeTwoWay(go.Point.stringify),
          {
              // the Node.location is at the center of each node
              //  locationSpot: go.Spot.Top,
              resizable: true, resizeObjectName: "SHAPE",  // user can resize the Shape
              rotatable: true, rotateObjectName: "SHAPE",  // user can rotate the Shape

              //isShadowed: true,
              //shadowColor: "#888",
              // handle mouse enter/leave events to show/hide the ports
              mouseEnter: function (e, obj) { showPorts(obj.part, true); },
              mouseLeave: function (e, obj) { showPorts(obj.part, false); }
          },
          new go.Binding("desiredSize").makeTwoWay(),
          new go.Binding("angle").makeTwoWay(),
        ];
    }

wiDiagram.nodeTemplateMap.add(“Number”,
$$(go.Node, “Spot”, nodeStyle(), new go.Binding(“zOrder”), { zOrder: 0 },
$$(go.Panel, “Auto”,
$$(go.Shape, “Circle”,
{ minSize: new go.Size(30, NaN), fill: stdColor, stroke: stdColor, strokeWidth: 2, geometryStretch: go.GraphObject.Fill },
new go.Binding(“fill”, “color”),
new go.Binding(“stroke”, “borderColor”),
new go.Binding(“strokeWidth”, “thickness”)),
//$$(go.TextBlock, “”,
// { font: “bold 11pt Helvetica, Arial, sans-serif”, stroke: lightText },
// new go.Binding(“text”))
$$(go.TextBlock,
{

                 margin: 1,
                 maxSize: new go.Size(17,17),
                 wrap: go.TextBlock.WrapFit,
                 textAlign: "center",
                 editable: true,
                 font: "bold 11pt Helvetica, Arial, sans-serif",
                 stroke: 'white'
             },
             new go.Binding("text").makeTwoWay()),
             {
                 contextMenu: new makeContextMenu(wiDiagram)
             }
         )
         // no ports, because no links are allowed to connect with a comment
       ));

please advise me on this

Circles always have the same height as width – you should be using an Ellipse shape.

Thanks for your response. it is working

您好,我不是特别明白,自定义图形后,选择的蓝框的大小如何设置成自定义图形的大小而不留白,以及如果放大缩小自定义图形,而不是放大缩小选择后显示的蓝框。最后这个蓝框具体是什么,怎么定义的呢?
