Is it possible to start a y-annotation based on x-index?

[RafaelCENG]

I want to create a y-axis annotation but I want it to start from my x-index 30 for example. The one way i found is to use width plus offset. The problem with this approach my line is not responsive. Any tips? Thanks in advance.

Here is my y-axis annotation

  {
          y: props.weeksAverage[data],
          borderColor: "#BC6D29",
          width: "24%",
          offsetX: 790,
          label: {
            borderColor: "#BC6D29",
            position: "right",
            style: {
              color: "#BC6D29",
              background: "#201B20",
            },
            text: `${Number(props.weeksAverage[data]).toFixed(2)}${
              props.activeTitle === "Normalised W" ? " W" : ""
            }`,
          },
        },
