How to add trendline to line chart highcharts in JSON - javascript

im currently struggling to create a trend line to a line chart. found some old solutions and those things didn't work for me.
Current code:

How do i add trend line to this line chart? is there any built in parameter to add trend line?

First, load and initialize indicators and trendline modules. Then add new trendline series. For example:
series: [{
id: "mainSeries",
name: "Week",
data: [...]
}, {
type: 'trendline',
linkedTo: "mainSeries"
}]

Highcharts .update modifying original data array

When a user selects the chart they want to view, I then grab the data needed charts[selectedIndex].series and pass that to:
chartObj.update({
series: charts[selectedIndex].series
}, false );
chartObj.redraw();
This overall works and the chart is updated correctly, however, chart[0].series gets updated with the last selected chart data. The chart array is getting modified for some odd reason. It only modifies the first chart in the array. For the life of me, I can't figure out why this is occurring. Any insight would be greatly appreciated.
I've also tried a for loop going through the chartObj series and matching it to the desired charts array item, and using .setData with the 'data' but that had it's own issues. This did not modify the original array, however the chart would no longer update. I tried the same loop with .update as well.
Codepen with the error: https://codepen.io/rossberenson/pen/mdrWgPe
I dug a little deeper and found that the chart.update() call was switching out the nested series array but wasn't updating the entire chart object, more than that even cloning the series array using map(o => ({...o})) doesn't clone the nested data arrays so they are still prone to mutation. (you could use map(o => ({...o, data: [...o.data]})) but it's fragile if your series/data structure changes).
So... here is a quick snippet that stores the datasets in their own array and sets the Highchart.series option to a separate active object.
The active object is initially assigned a cloned version of the first chart object using JSON for deep cloning – see this question for deeper discussion of its shortcomings and better options What is the most efficient way to deep clone an object in JavaScript?
When the select change event fires, the chart object at the newly selected index is cloned using the same method and assigned to the active object.
Finally, chart.update() is called pointing to the same active.series as when the highchart class was instantiated.
const cloneSample = (sample) => {
// Crude JSON deep clone – see referenced question for discussion
return JSON.parse(JSON.stringify(sample));
}
let active = cloneSample(samples[0]);
const highchart = Highcharts.chart('container', {
chart: { type: 'bar' }, title: { text: active.title },
xAxis: { categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas'] },
yAxis: { min: 0, title: { text: 'Total fruit consumption' } }, legend: { reversed: false },
plotOptions: { series: { stacking: 'normal' } },
series: active.series
});
const select = document.querySelector('.select');
select.addEventListener('change', () => {
let
selected = select.value,
newSample = cloneSample(samples[selected]);
active = newSample;
highchart.update({
title: { text: active.title },
series: active.series,
});
});

Group x axis labels

I need to group (and show) labels of X axis of a grahp, but still showing all single labels.
This is the code I actually use, and its a normal column2d graph:
FusionCharts.ready(function() {
var myChart = new FusionCharts({
type: "column2d",
renderAt: "chart",
width: "100%",
height: "100%",
dataFormat: "json",
dataSource: {
"chart": {
"animation": 0,
"caption": "Graph title",
"xAxisName": "Performance",
"baseFontColor": "#000000",
},
"data": [
{
"label": "351-08",
"value": "91"
},
{
"label": "351-09",
"value": "90"
},
{
"label": "351-10",
"value": "94"
},
{
"label": "351-01",
"value": "99"
},
{
"label": "351-07",
"value": "92"
},
{
"label": "351-06",
"value": "81"
},
],
"trendlines": [
{
"line": [
{
"startvalue": "82",
"color": "#ff3333",
"thickness": "5",
"valueOnRight": "1",
"displayvalue": "Average"
}
]
}
]
}
}).render();
});
What I need is showing another label on X axis that groups labels.
For example:
Group 1: [label1, label2];
Group 2: [label3, label4, label5];
Group 3: [label6];
UPDATED
I attached an image of what I need.
As you can see I need another labels line ("Fattore1", "Fattore2" and "Fattore3") that group other labels.

How to get value outside click function

I have a div of a map and a div of pie chart on the web page. There are several pins on the map, and I want to refresh the chart div based on different click.
Here is the click function of leaflet.js:
var country = "";
map.on('click', function(e) {
country = "Worldwide";
alert("Set map to worldwide");
});
markerUS.on('click', function(e) {
country = "U.S.";
alert('U.S');
});
in the chart.js (pie chart):
AmCharts.makeChart("chartdiv1", {
"type": "pie",
"angle": 12,
"balloonText": "[[title]]<br><span style='font-size:14px'><b>[[value]]</b> ([[percents]]%)</span>",
"depth3D": 15,
"titleField": "category",
"valueField": "column-1",
"allLabels": [],
"balloon": {},
"legend": {
"enabled": true,
"align": "center",
"markerType": "circle"
},
"titles": [{
"id": "Title-1",
"size": 15,
"text": "Number of Projects distribution of " + country
}],
"dataProvider": [{
"category": "a",
"column-1": 8
},
{
"category": "b",
"column-1": 6
},
{
"category": "c",
"column-1": 2
},
{
"category": "d",
"column-1": "3"
},
{
"category": "e",
"column-1": "4"
},
{
"category": "f",
"column-1": "2"
}
]
});
inside "titles" I make country as variable based on the pin I clicked.
But I got country is undefined and the value country from leaflet.js seems didn't pass to chart.js. Why? How to correct this and realize the function?
You got undefined country because its value only be initialized when user click on map or on a maker. You could try to update your code like this
map.on('click', function(e) {
var country = "Worldwide";
makeChart(country);
});
markerUS.on('click', function(e) {
var country = "U.S.";
makeChart(country);
});
function makeChart(country) {
AmCharts.makeChart("chartdiv1", {
// your chart option ....
});
}
As Trung said you need to call a function that refrech the chart on each click event
var country = "";
map.on('click', function(e) {
country = "Worldwide";
refrechChart(country);
});
markerUS.on('click', function(e) {
country = "U.S.";
refrechChart(country);
});
and then make the refrechChart function
function refrechChart(country) {
AmCharts.makeChart("chartdiv1", {
"type": "pie",
"angle": 12,
"balloonText": "[[title]]<br><span style='font-size:14px'><b>[[value]]</b> ([[percents]]%)</span>",
"depth3D": 15,
"titleField": "category",
"valueField": "column-1",
"allLabels": [],
"balloon": {},
"legend": {
"enabled": true,
"align": "center",
"markerType": "circle"
},
"titles": [{
"id": "Title-1",
"size": 15,
"text": "Number of Projects distribution of " + country
}],
"dataProvider": [{
"category": "a",
"column-1": 8
},
{
"category": "b",
"column-1": 6
},
{
"category": "c",
"column-1": 2
},
{
"category": "d",
"column-1": "3"
},
{
"category": "e",
"column-1": "4"
},
{
"category": "f",
"column-1": "2"
}
]
});
}
you can also pass more parameter to use in your chart like
function refrechChart(country,value1,value2) {
//...
}

Animation of line chart with D3.js (v4)?

Is it possible to create an animation with D3.js (version 4)? In particular I want to create multiple line charts that "runs" from left to right like in this example with react-fusionchart:
http://jsfiddle.net/thadeuszlay/m18qaekm/12/
(just look at the example above.)
FusionCharts.ready(function () {
var myDataSource = {
"chart": {

"subcaption": "Last year",
"xaxisname": "Month",
"yaxisname": "Amount (In USD)",

}, {

}, {

}, {
"label": "Jun"
}, {
"label": "Jul"
}, {
"label": "Aug"
}, {

}, {
"value": "21000"
}, {
"value": "22000"
}, {
"value": "23000"
}]
}]
};
var chartConfigs = {
id: "revenue-profits-chart",
renderAt: "revenue-profits-chart-container",
type: "mscombi2d",
width: 600,
height: 400,
dataFormat: "json",
dataSource: myDataSource
};
React.render( < react_fc.FusionCharts {...chartConfigs
}
/>,
document.getElementById("chart-container")
);
});
Yes you can do that: you just need to replace the methods that have changed from d3 v3 to v4, such as:
var parse = d3.timeParse("%b %Y");
var x = d3.scaleTime().range([0, width]),
y = d3.scaleLinear().range([height, 0]),
xAxis = d3.axisBottom(x).tickSize(-height),
yAxis = d3.axisLeft(y).tickArguments(4);
Etc. Etc.
You can find the working example on my bl.ocks.
My example is the v4 update of another bl.ocks.
Hope that helps.

LabelDisplay for fusion charts MScombi3d charts

I need some help in displaying the xaxis labels for a MSCombi3d chart. I have checked and for 2d charts, there are below two attributes available. which when we set in the chart, the x axis labels will display in a rotated format.
labelDisplay='Rotate' & slantLabels='1'
But when I try to use the above for a MScombi3d chart it doesnot work. I have gone through the documentation and could only find this attribute xLabelGap='50'. But it does not rotate/display the x axis labels in a slant.
Can someone please suggest the attribute that needs to be used for MSCombi3d charts to display the x axis labels in a slant.
Any help on this is much appreciated.
The attribute xLabelGap is perhaps a deprecated or at least not applicable in FusionCharts Javascript version. Although I found some usage of this attribute here, but nowhere in the official FusionCharts docs
I found the attributes labelDisplay and slantLabels in MSCombi3d charts(JS version) functional since its 3.4.0 version. Might work before that too! :D
Below snippet illustrates the use of these attributes with its latest version. You can visit the download page.
