   as an alternative fix you can use the below code to generate multiple mark lines so that even with zoom you will have it working
   
   const getCoords = (xMin = 0, yMin = 0, xMax = 1, yMax = 1, accuracy = 10) => {
   	const xDiff = (xMax - xMin) / accuracy;
   	const yDiff = (yMax - yMin) / accuracy;
   	let presentXVal = xMin;
   	let presentYVal = yMin;
   	const dataArr = [];
   	while (presentXVal <= xMax) {
   		let coordArr: { coord: number[] }[] = [];
   		coordArr = [{ coord: [presentXVal, presentYVal] }];
   		presentXVal += xDiff;
   		presentYVal += yDiff;
   		coordArr.push({ coord: [presentXVal, presentYVal] });
   		dataArr.push(coordArr);
   	}
   	return dataArr;
   };
