Neo4j Grass能否通过属性设置节点尺寸？设置后节点消失

First off, yes—you absolutely can use a custom property to define node dimensions in .grass. The reason your node is disappearing is because of a mismatch between the property value format and what the .diameter parameter expects.

The Root Cause #

Your diameter property is set to "50px" (a string with a unit), but the .diameter configuration option in .grass expects a raw numeric value (it assumes pixels by default). When you pass a string with px, the renderer can't parse it correctly, so the node fails to render entirely.

Solution 1: Use Numeric Property Value (Simplest Fix) #

1. Update your diameter property to be a pure number instead of a string with units: set it to 50 (not "50px").
2. Keep your existing configuration code—it will work correctly now:

"node.User": {
  "color": "#FB95AF",
  "border-color": "#E0849B",
  "text-color-internal": "#FFFFFF",
  "caption": "{name}",
  "diameter": "{diameter}"
}

This tells the renderer to create a node with a 50px diameter, which is the default unit for the .diameter field.

Solution 2: Custom Units (If You Need Them) #

If you need to use units other than pixels (like em, %, or rem), you can leverage the style property to set explicit width and height instead of using .diameter:

1. Keep your diameter property as "50px" (or any unit you need).
2. Modify your configuration to use inline styles:

"node.User": {
  "color": "#FB95AF",
  "border-color": "#E0849B",
  "text-color-internal": "#FFFFFF",
  "caption": "{name}",
  "style": "width: {diameter}; height: {diameter}; border-radius: 50%;"
}

The border-radius: 50% ensures the node stays circular, matching the behavior of the .diameter parameter.

Either approach should bring your node back and let you control its size via the custom property.
