我指的是preview中可用的代码后面的VEGA图表。 “域”:[0,3]用于x和y轴的设定范围。这里如果我设置[-0.5,3],x轴将从-0.5开始,但是如果我想要有正数,例如0.5,那么x轴将不会从该值开始而是从0开始。有没有其他选择如何解决这个问题?

        {"x":2.5, "y":2.5, "img":"data/7zip.png"}
      ]
    }

        },
        "update": {
          "opacity": {"value": 1.0}

        "hover": {

        }
      }
