Currently, I'm showing a max point in the line chart. But I want to change dataMax to top 5 max value points in chart.How can I achieve this in Highcharts?
var defaultData = 'urlto.csv';
var urlInput = document.getElementById('fetchURL');
var pollingCheckbox = document.getElementById('enablePolling');
var pollingInput = document.getElementById('pollingTime');
function createChart() {
Highcharts.chart('closed5', {
chart: {
type: 'area',
zoomType: 'x'
},
plotOptions: {
series: {
dataLabels: {
enabled: true,
style: {},
formatter: function() {
if (this.y === this.series.dataMax) {
return this.y;
}
}
}
}
},
title: {
text: 'Chart for charting'
},
data: {
csvURL: urlInput.value,
enablePolling: pollingCheckbox.checked === true,
dataRefreshRate: parseInt(pollingInput.value, 10)
}
});
if (pollingInput.value < 1 || !pollingInput.value) {
pollingInput.value = 1;
}
}
urlInput.value = defaultData;
// We recreate instead of using chart update to make sure the loaded CSV
// and such is completely gone.
pollingCheckbox.onchange = urlInput.onchange = pollingInput.onchange = createChart;
// Create the chart
createChart();
As #ewolden rightly noticed, you can sort your data and show only the five highest values:
var data = [11, 22, 33, 44, 55, 66, 15, 25, 35, 45, 55, 65],
sortedData = data.slice().sort(function(a, b){
return b - a
});
Highcharts.chart('container', {
series: [{
data: data,
dataLabels: {
enabled: true,
formatter: function() {
if (sortedData.indexOf(this.y) < 5) {
return this.y;
}
}
}
}]
});

As far as I know formatter callback is the way to format the data labels. If you want to show the top N points you should sort the data in a new array and pull the top 5 values. This is an example of how to clone and sort the array and extract the top 5 elements in the formatter call.
let data = [32, 10, 20, 99, 30, 54, 85, 56, 11, 26, 15, 45, 55, 65];
//Copy the array
let temp = data.slice();
// Sort the temp array in descending order
temp.sort((a, b) => b - a);
Highcharts.chart('closed5', {
chart: {
type: 'area',
zoomType: 'x'
},
title: {
text: 'Chart for charting'
},
series: [{
data: data,
dataLabels: {
enabled: true,
formatter: function() {
if (temp.indexOf(this.y) < 5) {
return this.y;
}
},
},
}]
});

When I clicked in legend, the plotBands parameters hide() and show() do not work.
I wish I could click on the legend and remove a specific PlotBand.
I tried using destroy() but it cleans the html dom and I can't return with PlotBand when I click on the legend again.
I couldn't find how to remove and put the PlotBand back on:
var a = 1,
b = 2,
c = 4,
d = 5,
dados = [[a, b, '#32CD32','manutenção','Mantuenção'], [c, d, '#FF0000','falha','Falha']];
Highcharts.chart('container', {
chart: {
zoomType: 'xy',
},
showInLegend: true,
title: {
text: 'Zoom Geral e Barras Verticais'
},
yAxis: {
scrollbar: {
enabled: true,
showFull: false
}
},
plotOptions: {
series: {
shadow:false,
borderWidth:0,
events:{
legendItemClick:function(e){
console.log(this.userOptions)
var ids = this.userOptions['id'];
console.log(ids)
if(this.userOptions['id'] === ids){
var hides = this.xAxis.plotLinesAndBands.filter(id => id.id == ids);
if(this.visible == true){
hides[0].svgElem.hide()
} else {
hides[0].svgElem.show()
}
}
}
}
}
},
series: [{
name:'Série A',
data: [-10, 31, 35, 40, 15, 10]
}
]
},
function(){
for (let i = 0; i < dados.length; i++ ){
this.xAxis[0].addPlotBand({
from: dados[i][0],
to: dados[i][1],
color: dados[i][2],
name: dados[i][4],
id: dados[i][3]
}, )
this.addSeries({
marker: {
symbol: 'square',
radius: 20},
name: dados[i][4],
color: dados[i][2],
type: 'scatter',
id: dados[i][3]
}, )
}
}
)
The plot bands are not hidden because the chart is redrawn after the event. You can return false from the callback function, but all plot bands will be visible after another redraw. Example: http://jsfiddle.net/BlackLabel/m2xrjhLk/
I recommend you to remove/add the plot band on legend click:
plotOptions: {
series: {
...,
events: {
legendItemClick: function(e) {
var id = this.options.id;
if (this.visible) {
this.xAxis.removePlotBand(id);
} else {
this.xAxis.addPlotBand(plotBands.find(
plotBand => plotBand.id === id
));
}
}
}
}
}

I'm having trouble aligning tooltip position on bar chart. Tooltip positioning works fine if all charts are line chart but not with bar/column charts. Could the Highcharts experts please help me with this issue?
http://jsfiddle.net/yhenwtsb/1/
var charts = [],
options1, options2;
function syncTooltip(container, p) {
var i = 0;
for (; i < charts.length; i++) {
if (container.id != charts[i].container.id) {
if (charts[i].tooltip.shared) {
charts[i].tooltip.refresh([charts[i].series[0].data[p]]);
} else {
charts[i].tooltip.refresh(charts[i].series[0].data[p]);
}
}
}
}
options1 = {
chart: {
type: "column",
inverted: true
},
plotOptions: {
series: {
point: {
events: {
mouseOver: function() {
syncTooltip(this.series.chart.container, this.x - 1);
}
}
}
}
},
xAxis: {
type: 'datetime'
}
};
options2 = {
plotOptions: {
series: {
point: {
events: {
mouseOver: function() {
syncTooltip(this.series.chart.container, this.x - 1);
}
}
}
}
},
xAxis: {
type: 'datetime'
}
};
charts[0] = new Highcharts.Chart($.extend(true, {}, options1, {
chart: {
renderTo: 'container1',
marginLeft: 40, // Keep all charts left aligned
},
tooltip: {
shared: true,
crosshairs: true,

},
series: [{
data: [
[1, 29.9],
[2, 71.5],
[3, 106.4]
]
}, {
data: [
[1, 59.9],
[2, 91.5],
[3, 136.4]
]
}]
}));
charts[1] = new Highcharts.Chart($.extend(true, {}, options2, {
chart: {
renderTo: 'container2',
marginLeft: 40, // Keep all charts left aligned
},
tooltip: {
shared: false
},
series: [{
data: [
[1, 29.9],
[2, 71.5],
[3, 106.4]
]
}]
}));
You can set tooltip.followPointer to true and add a small plugin to synchronize the second chart:
(function(H) {
H.wrap(H.Pointer.prototype, 'runPointActions', function(proceed, e, p) {
proceed.apply(this, Array.prototype.slice.call(arguments, 1));
var tooltipPos = this.chart.tooltip.now;
Highcharts.charts.forEach(function(chart) {
if (chart !== this.chart) {
chart.tooltip.updatePosition({
plotX: tooltipPos.x - chart.plotLeft,
plotY: tooltipPos.y - chart.plotTop
});
}
}, this);
});
}(Highcharts));

I was under the assumption the "Play with this data!" link was supposed the show up by default. Any ideas on why it may not appear? I am just working with a basic scatter plot.
Note that this code below is not standalone as is, it is just the excerpt that does the plotly work.
var xData = [];
var yData = [];
var h = results;
for(var k in h) {
var localdate = k;
var plotdate = moment(localdate).format('YYYY-MM-DD HH:mm:ss');
xData.push(plotdate);
if (currentPort === "t") {
yData.push(CtoF(h[k]));
} else {
yData.push(h[k]);
};
}
var plotdata = [
{
x: xData,
y: yData,
type: 'scatter',
mode: 'markers+lines',
line: {
'color': HELIUM_BLUE
},
marker: {
'symbol': 'circle',
'color': HELIUM_PINK,
'maxdisplayed': 50
}
}
];
var layout = {
title: currentData,
xaxis: {
'title': 'Date / Time'
},
yaxis: {
'title': title
}
};
Plotly.newPlot(plotHolder, plotdata, layout);
You would need to add {showLink: true} as the fourth argument (after layout). I guess the default value changed from true to false.
If you want to change the caption of the button, use {showLink: true, "linkText": "Play with this data"}
var xData = [1, 2, 3, 4, 5];
var yData = [10, 1, 25, 12, 9];
var plotdata = [
{
x: xData,
y: yData,
type: 'scatter',
mode: 'markers+lines',
}
];
var layout = {
title: 'Edit me',
xaxis: {
'title': 'x'
},
yaxis: {
'title': 'y'
}
};
Plotly.newPlot(plotHolder, plotdata, layout, {showLink: true, "linkText": "Play with this data"});

Im building a chart system that will show me all data entries. I retrieve my data using ajax and I loop trough the data and group the results by colors (red, blue and yellow) and then divide them by months.
I setup base objects (dateCounts_Red, dateCounts_Blue and dateCounts_Yellow) so that by default it starts all months at 0. A counter would then add when it finds a match tot he apropriate color and month.
When I output my dateCounts I get:
{"2015":{"2015-12":1,"2015-10":null,"2015-08":null,"2015-11":null}}
{"2015":{"2015-12":0,"2015-10":null}}

Im currently getting the following error from my Highcharts js:
Uncaught TypeError: Cannot set property 'index' of undefined
THis is preventing the chart system to work correctly the data returned is not being returned with it's expected data.
Here a full example to the issue https://jsfiddle.net/awo5aaqb/21/
Would anyone know what im missing?
Your date count objects have major structural flaw.
When you prettify them they look like:
var dateCounts_Blue = {
"2015": {
"2015-01": 0,
"2015-02": 0,
"2015-03": 0,
"2015-04": 0
},
"2015": {
"2015-05": 0
},
"2015": {
"2015-06": 0
},
"2015": {
"2015-07": 0
},
......
Object keys must be unique so these are clearly being repeated and the compiler will over write duplicates.
Fix the pattern that breaks away from the intended pattern grouping at the beginning
var dateCounts_Red = {
"2015":
{
"2015-01":0,
"2015-02":0,
"2015-03":0,
"2015-04":0,
"2015-05":0,
"2015-06":0,
"2015-07":0,
"2015-08":0,
"2015-09":0,
"2015-10":0,
"2015-11":0,
"2015-12":0
},
};
var dateCounts_Blue = {
"2015":{
"2015-01":0,
"2015-02":0,
"2015-03":0,
"2015-04":0,
"2015-05":0,
"2015-06":0,
"2015-07":0,
"2015-08":0,
"2015-09":0,
"2015-10":0,
"2015-11":0,
"2015-12":0
}
};
var dateCounts_Yellow = {
"2015":{
"2015-01":0,
"2015-02":0,
"2015-03":0,
"2015-04":0,
"2015-05":0,
"2015-06":0,
"2015-07":0,
"2015-08":0,
"2015-09":0,
"2015-10":0,
"2015-11":0,
"2015-12":0}
};
Your data structure is flawed and such comparing values when doing the foreach loop becomes inconsistent because it compares it to multiple values, the above JSON is the fix for your problem.
Not quite codereview.stackexchange.com, but I heavily modified your javascript to make it work a bit better

success: function(data) {
var counts = {};
data.d.results.forEach(function(element) {
// If you know it's all the same year, you could totally ignore this
var yr = element.created_date.slice(0, 4);
var month = parseInt(element.created_date.slice(5,7));
var color = element.colorvalue;
if (counts[color] === undefined) {
counts[color] = {};
}
if (counts[color][yr] === undefined) {
counts[color][yr] = {};
}
current_value = counts[color][yr][month];
if (current_value === undefined) {
// Doesnt exist yet, so add it
counts[color][yr][month] = 1;
} else {
// Exists, so increment by 1
counts[color][yr][month] = current_value + 1;
}
});

I've got a basic variable width column chart (aka Marimekko) set up using Highcharts but am having trouble getting it to restack the columns properly to eliminate the data gap once a series has been removed or hidden.
JSFIDDLE DEMO <-- I've set up a demo of the issue here.
You'll notice clicking on a legend item removes the series from the chart, but it also removes all of the following data points in the array (i.e. clicking on series C removes series C, D, and E whereas it should redraw to A-B-D-E). Since the y-axis data is meant to display a cumulative sum of all series, these should re-shuffle as adjacent columns with no gaps. How can I get this to render properly?
THIS POST uses similar demo code and attempting to solve the same problem, however the answer is somewhat elusive and I am unable to get it working.
Thanks in advance!
