Amcharts - 눈금선을 제거하지만 기본 x 및 y 축을 유지하는 방법

Amcharts4에서 격자선만 제거하고 x축 및 y축 기준선을 유지하려면 어떻게 해야 합니까? Vuejs와 함께 Amcharts를 사용하고 있습니다. 여기 차트 구성 요소의 코드

<template>
    <b-card>
        <div class="d-flex align-items-center justify-content-between">
            <h5>Real Time</h5>
        </div>
        <div class="real-time-graph mt-4" ref="chartdiv"></div>
    </b-card>
</template>

<script>
    import * as am4core from "@amcharts/amcharts4/core";
    import * as am4charts from "@amcharts/amcharts4/charts";
    import am4themes_animated from "@amcharts/amcharts4/themes/animated";

    am4core.useTheme(am4themes_animated);

    export default {
        name: "main-details",
        mounted() {
           let chart = am4core.create(this.$refs.chartdiv, am4charts.XYChart);

            chart.data = [{
                "date": "2020-01-01",
                "value1": 180,
                }, {
                "date": "2020-01-08",
                "value1": 300,
                }, {
                "date": "2020-01-15",
                "value1": 160,
                }, {
                "date": "2020-01-22",
                "value1": 650,
                }, {
                "date": "2020-01-29",
                "value1": 220,
                }, {
                "date": "2020-02-05",
                "value1": 440,
                }, {
                "date": "2020-02-12",
                "value1": 550,
                }, {
                "date": "2020-02-19",
                "value1": 290,
                }, {
                "date": "2020-02-26",
                "value1": 440,
                }, {
                "date": "2020-03-04",
                "value1": 150,
                }, {
                "date": "2020-03-11",
                "value1": 430,
                }];

            // Set input format for the dates
            chart.dateFormatter.inputDateFormat = "yyyy-MM-dd";
            chart.numberFormatter.numberFormat = '#,###w';

            // Create axes
            var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
            dateAxis.renderer.minGridDistance = 50;
            dateAxis.renderer.grid.template.disabled = true; 
            dateAxis.renderer.line.disabled = false;
            dateAxis.renderer.ticks.template.disabled = true;
            dateAxis.renderer.labels.template.fill = am4core.color("#C3CDDD");
          
            var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
            valueAxis.renderer.grid.template.disabled = true; 
            valueAxis.renderer.labels.template.fill = am4core.color("#C3CDDD");

            // Create series
            var series1 = chart.series.push(new am4charts.StepLineSeries());
            series1.dataFields.valueY = "value1";
            series1.dataFields.dateX = "date";
            series1.strokeWidth = 2;
            series1.stroke = "#3AB7FD";

            series1.fillOpacity = 1;
            var gradient1 = new am4core.LinearGradient();
            gradient1.addColor(chart.colors.getIndex(0), 0.2);
            gradient1.addColor(chart.colors.getIndex(0), 0);
            gradient1.rotation = 90;
            series1.fill = gradient1;
        
        }
    }
</script>

다음을 사용하여 축과 눈금선이 모두 제거됩니다.

dateAxis.renderer.ticks.template.disabled = true;
valueAxis.renderer.grid.template.disabled = true; 

위 코드의 출력 그래프입니다. x 및 y 기본 축을 모두 표시하고 눈금선만 제거해야 합니다.
