Prevent clipping of bullets at extreme ends in AmChart

I have taken the below code from the official documentation of AmChart and added the bullets on it.

// Create chart instance
var chart = am4core.create("chartdiv", am4charts.XYChart);
chart.colors.step = 2;

// Add data
chart.data = [{
  "year": "1995",
  "cars": 1567,
  "motorcycles": 683,
  "bicycles": 146
}, {
  "year": "1996",
  "cars": 1617,
  "motorcycles": 691,
  "bicycles": 138
}, {
  "year": "1997",
  "cars": 1630,
  "motorcycles": 642,
  "bicycles": 127
}, {
  "year": "1998",
  "cars": 1660,
  "motorcycles": 699,
  "bicycles": 105
}, {
  "year": "1999",
  "cars": 1683,
  "motorcycles": 721,
  "bicycles": 109
}, {
  "year": "2000",
  "cars": 1691,
  "motorcycles": 737,
  "bicycles": 112
}, {
  "year": "2001",
  "cars": 1298,
  "motorcycles": 680,
  "bicycles": 101
}];

// Create axes
var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "year";
categoryAxis.title.text = "Year";
categoryAxis.renderer.grid.template.location = 0;
categoryAxis.renderer.minGridDistance = 20;

categoryAxis.startLocation = 0.5;
categoryAxis.endLocation = 0.5;


var  valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
valueAxis.title.text = "Percent";
valueAxis.calculateTotals = true;
valueAxis.min = 0;
valueAxis.max = 100;
valueAxis.strictMinMax = true;
valueAxis.renderer.labels.template.adapter.add("text", function(text) {
  return text + "%";
});

// Create series
var series = chart.series.push(new am4charts.LineSeries());
series.dataFields.valueY = "cars";
series.dataFields.valueYShow = "totalPercent";
series.dataFields.categoryX = "year";
series.name = "Cars";

series.tooltipHTML = "<img src='https://www.amcharts.com/lib/3/images/car.png' style='vertical-align:bottom; margin-right: 10px; width:28px; height:21px;'><span style='font-size:14px; color:#000000;'><b>{valueY.value}</b></span>";

series.tooltip.getFillFromObject = false;
series.tooltip.background.fill = am4core.color("#FFF");

series.tooltip.getStrokeFromObject = true;
series.tooltip.background.strokeWidth = 3;

series.fillOpacity = 0.85;
series.stacked = true;

// static
series.legendSettings.labelText = "Cars total:";
series.legendSettings.valueText = "{valueY.close}";

// hovering
series.legendSettings.itemLabelText = "Cars:";
series.legendSettings.itemValueText = "{valueY}";

var series2 = chart.series.push(new am4charts.LineSeries());
series2.dataFields.valueY = "motorcycles";
series2.dataFields.valueYShow = "totalPercent";
series2.dataFields.categoryX = "year";
series2.name = "Motorcycles";

series2.tooltipHTML = "<img src='https://www.amcharts.com/lib/3/images/motorcycle.png' style='vertical-align:bottom; margin-right: 10px; width:28px; height:21px;'><span style='font-size:14px; color:#000000;'><b>{valueY.value}</b></span>";

series2.tooltip.getFillFromObject = false;
series2.tooltip.background.fill = am4core.color("#FFF");

series2.tooltip.getStrokeFromObject = true;
series2.tooltip.background.strokeWidth = 3;

series2.fillOpacity = 0.85;
series2.stacked = true;

// static
series2.legendSettings.labelText = "Motorcycles total:";
series2.legendSettings.valueText = "{valueY.close}";

// hovering
series2.legendSettings.itemLabelText = "Motorcycles:";
series2.legendSettings.itemValueText = "{valueY}";

var series3 = chart.series.push(new am4charts.LineSeries());
series3.dataFields.valueY = "bicycles";
series3.dataFields.valueYShow = "totalPercent";
series3.dataFields.categoryX = "year";
series3.name = "Bicycles";
series3.tooltipText = "{name}: [bold]{valueY}[/]";

series3.tooltipHTML = "<img src='https://www.amcharts.com/lib/3/images/bicycle.png' style='vertical-align:bottom; margin-right: 10px; width:28px; height:21px;'><span style='font-size:14px; color:#000000;'><b>{valueY.value}</b></span>";

series3.tooltip.getFillFromObject = false;
series3.tooltip.background.fill = am4core.color("#FFF");

series3.tooltip.getStrokeFromObject = true;
series3.tooltip.background.strokeWidth = 3;

series3.fillOpacity = 0.85;
series3.stacked = true;

// static
series3.legendSettings.labelText = "Bicycles total:";
series3.legendSettings.valueText = "{valueY.close}";

// hovering
series3.legendSettings.itemLabelText = "Bicycles:";
series3.legendSettings.itemValueText = "{valueY}";

// For adding bullets on the chart
var bullet = series.bullets.push(new am4charts.CircleBullet());
bullet.circle.stroke = am4core.color('#fff');
bullet.circle.strokeWidth = 1;
bullet.circle.radius = 10;
bullet.circle.opacity = 1;
bullet.circle.locationX = 0.6;

// Add cursor
chart.cursor = new am4charts.XYCursor();

// add legend
chart.legend = new am4charts.Legend();

The chart generated by the above code looks like below,

enter image description here

The leftmost and rightmost bullets are getting clipped off, how can I prevent that from happening. Shifting categoryAxis.startLocation and categoryAxis.endLocation solves the issue but it shifts the entire axis also, is there any other way to prevent the clipping of bullets?

Solution

  • If you want to prevent the bullets from getting clipped, set maskBullets to false in the chart object, as documented here

    chart.maskBullets = false;

    Demo below:

    // Create chart instance
var chart = am4core.create("chartdiv", am4charts.XYChart);
chart.colors.step = 2;
chart.maskBullets = false;

// Add data
chart.data = [{
  "year": "1995",
  "cars": 1567,
  "motorcycles": 683,
  "bicycles": 146
}, {
  "year": "1996",
  "cars": 1617,
  "motorcycles": 691,
  "bicycles": 138
}, {
  "year": "1997",
  "cars": 1630,
  "motorcycles": 642,
  "bicycles": 127
}, {
  "year": "1998",
  "cars": 1660,
  "motorcycles": 699,
  "bicycles": 105
}, {
  "year": "1999",
  "cars": 1683,
  "motorcycles": 721,
  "bicycles": 109
}, {
  "year": "2000",
  "cars": 1691,
  "motorcycles": 737,
  "bicycles": 112
}, {
  "year": "2001",
  "cars": 1298,
  "motorcycles": 680,
  "bicycles": 101
}];
