Im dealing with this problem. I have smoothed line chart from amcharts v5.
And everything is working properly until i want to add second line to the chart. It only displays one line chart. And i need to add second line to the same chart.
If I change data values to another chart. It is working fine but same problem, only one line.
So my question is, how to add second line into same chart.
am5.ready(function() {
// Create root element
// https://www.amcharts.com/docs/v5/getting-started/#Root_element
var root = am5.Root.new("chartdiv");
// Set themes
// https://www.amcharts.com/docs/v5/concepts/themes/
root.setThemes([
am5themes_Animated.new(root)
]);
// Create chart
// https://www.amcharts.com/docs/v5/charts/xy-chart/
var chart = root.container.children.push(am5xy.XYChart.new(root, {
panX: true,
panY: true,
wheelX: "panX",
wheelY: "zoomX",
pinchZoomX:true
}));
// Add cursor
// https://www.amcharts.com/docs/v5/charts/xy-chart/cursor/
var cursor = chart.set("cursor", am5xy.XYCursor.new(root, {
behavior: "none"
}));
cursor.lineY.set("visible", false);
function generateDataInvestice(roky,investice) {
value = investice;
return {
date: roky,
value: value
};
}
function generateDatasInvestice(count,i) {
var data = [];
var investice = 5;
for (var i = 1; i < count; ++i) {
data.push(generateDataInvestice(i,investice));
}
return data;
}
//generate uver
function generateDataUver(roky,uver) {
value = uver;
return {
date: roky,
value: value
};
}
function generateDatasUver(count,i) {
var data = [];
var uver = 1;
for (var i = 1; i < count; ++i) {
data.push(generateDataUver(i,uver));
}
return data;
}
// Create axes
// https://www.amcharts.com/docs/v5/charts/xy-chart/axes/
var xAxis = chart.xAxes.push(am5xy.ValueAxis.new(root, {
maxDeviation: 1,
baseInterval: {
count: 1
},
renderer: am5xy.AxisRendererX.new(root, {
pan:"zoom"
}),
tooltip: am5.Tooltip.new(root, {})
}));
var yAxis = chart.yAxes.push(am5xy.ValueAxis.new(root, {
maxDeviation:1,
renderer: am5xy.AxisRendererY.new(root, {
pan:"zoom"
})
}));
// Add series
// https://www.amcharts.com/docs/v5/charts/xy-chart/series/
var series = chart.series.push(am5xy.SmoothedXLineSeries.new(root, {
name: "Series",
xAxis: xAxis,
yAxis: yAxis,
valueYField: "value",
valueXField: "date",
tooltip: am5.Tooltip.new(root, {
labelText: "{valueY}"
})
}));
series.fills.template.setAll({
visible: true,
fillOpacity: 0.2
});
series.bullets.push(function() {
return am5.Bullet.new(root, {
locationY: 0,
sprite: am5.Circle.new(root, {
radius: 4,
stroke: root.interfaceColors.get("background"),
strokeWidth: 2,
fill: series.get("fill")
})
});
});
var data = generateDatasInvestice(30,0);
var data_uver = generateDatasUver(30,0);
series.data.setAll(data,data_uver);
series.appear(30);
chart.appear(1000, 100);
}); // end am5.ready()
Here is working soluiton on codepen: https://codepen.io/tom-august/pen/KKQLgbm
Thanks a lot.
In your data, you should have several value fields like so:
var data = [
{
date: new Date("2022-12-27").getTime(),
value1: 10,
value2: 20
},
{
date: new Date("2022-12-28").getTime(),
value1: 20,
value2: 30
},
{
date: new Date("2022-12-29").getTime(),
value1: 10,
value2: 20
}
];
Then you need to create a series for each line that you want to display, associating each series with the corresponding value field. This can be done using a function:
function createSeries(name, field) {
var series = chart.series.push(am5xy.SmoothedXLineSeries.new(root, {
name: name,
xAxis: xAxis,
yAxis: yAxis,
valueXField: "date",
valueYField: field
}));
series.data.setAll(data);
}
createSeries("Series 1", "value1");
createSeries("Series 2", "value2");
am5.ready(function() { var root = am5.Root.new("chartdiv"); var chart = root.container.children.push(am5xy.XYChart.new(root, {})); var data = [ { date: new Date("2022-12-27").getTime(), value1: 10, value2: 20 }, { date: new Date("2022-12-28").getTime(), value1: 20, value2: 30 }, { date: new Date("2022-12-29").getTime(), value1: 10, value2: 20 } ]; var xAxis = chart.xAxes.push(am5xy.DateAxis.new(root, { baseInterval: { timeUnit: "day", count: 1 }, renderer: am5xy.AxisRendererX.new(root, {}), })); var yAxis = chart.yAxes.push(am5xy.ValueAxis.new(root, { renderer: am5xy.AxisRendererY.new(root, {}) })); function createSeries(name, field) { var series = chart.series.push(am5xy.SmoothedXLineSeries.new(root, { name: name, xAxis: xAxis, yAxis: yAxis, valueXField: "date", valueYField: field })); series.data.setAll(data); } createSeries("Series 1", "value1"); createSeries("Series 2", "value2"); });
