I would like to have a plotline at today's date. The list can get quite long and in that case it helps with having an oversight. I fear it doesn't work because it is a scatter chart but I don't know what the problem is. I've searched all over the place but everything leads to plotlines, which clearly doesn't work. I would also be thankful if anyone knew, whether there was an easy way to filter my data the way I have it (standard highcharts filtering is deactivated but doesn't really help because of the static y values, so I get a huge, white space in the middle unless I filter at the edges. Thank you in advance for your help.

You have a typo, use plotLines instead of plotlines:
xAxis: {
plotLines: [{

Hi, everyone!! I am working on the echarts library, the only thing i want to change data is the axisLabel from Xaxis part.
What i mean is, for example, "2019-11-5, 2019-11-6...."and so on. So, i hope someone can help me out, thank you so much!!!
Hi, everyone!! I am working on the echarts library, the only thing i want to change data is the axisLabel from Xaxis part.
What i mean is, for example, "2019-11-5, 2019-11-6...."and so on. So, i hope someone can help me out, thank you so much!!!
First, create an array of dates like
var dates = ['2019-11-5','2019-10-3','2019-2-2','2019-1-4','2019-12-5'];
then in xAxis -> axisLabel return date
axisLabel: {
formatter: function (val,index) {
return dates[index];
}
}
Hello I'm having a problem with my code in Highcharts I already declared my series but it only shows 1 set of chart. All data were set on var dataStr, on how the data that being put, I use push on every data that is being passed. So I think the problem is the with my push?
var dataStr = [
{name: 'JOB-182', problemReportCount: 0, totalCost: 50000, lostHour: 0, lostValue: 0},
{name: 'JOB-185', problemReportCount: 0, totalCost: 3432.65, lostHour: 0, lostValue: 0},
{name: 'JOB-188', problemReportCount: 4, totalCost: 5000, lostHour: 0, lostValue: 0},
{name: 'JOB-189', problemReportCount: 0, totalCost: 1000, lostHour: 0, lostValue: 0}
];
var jRefs = [];
var prJRefs = [];
var prLostVals = [];
var prLostHours = [];
var totCosts = [];
for (var i = 0; i < dataStr.length; i++) {
var jName = '' + dataStr[i].name;
if (jName != '') {
jRefs.push(jName);
var prCount = dataStr[i].problemReportCount;
if (prCount > 0) {
prJRefs.push(jName);
prLostVals.push(dataStr[i].lostValue);
prLostHours.push(dataStr[i].lostHour);
totCosts.push(dataStr[i].totalCost);
}
}
}
var genGraph = function() {
$("#backButton").hide();
$('#prGraph4').highcharts({
chart: {
type: 'column',
plotBackgroundColor: '#F7F7F7'
},
title: {
text: 'Problem Report'
},
subtitle: {
text: 'Estimated Lost Values'
},
xAxis: {

var s = '<b>' + this.x + '</b>';
$.each(this.points, function() {
var lostValue = this.y;
s += '<br/><span style=" + dbl + "color:' + this.series.color + ';" + dbl + ">\u25CF</span> ' + this.series.name + ': <b>£</b> ' + lostValue.toFixed(2);
});
return s;
}
},
series:[{
name: 'Total Costs',
data: totCosts,
color: '#2ecc71',
stack: 'total'
}, {
name: 'Estimated Lost Materials Value',
data: prLostVals,
color: '#e74c3c',
stack: 'lost'
}, {
name: 'Estimated Lost Hours Price',
data: prLostHours,
color: '#e67e22',
stack: 'lost'
}]
});
};
Any help would be so much appreciated. Thanks!
You have only one visible column because only one set of data fulfills this condition:
if (prCount > 0) {
prJRefs.push(jName);
prLostVals.push(dataStr[i].lostValue);
prLostHours.push(dataStr[i].lostHour);
totCosts.push(dataStr[i].totalCost);
}
In addition, all values from series: Estimated Lost Materials Value and Estimated Lost Hours Price are 0.

I am trying to create a gantt chart representation in highcharts with navigator. I get a JSON response from server (below is a typical response strucutre). In order to create a gantt chart representation I am creating a line between 2 points. Each point has a start_date and end_date and inorder to create this representation I am plotting a line between start_date and end_date of each point (which I have accomplished).

I have sorted data (ascending order) but I am still getting Highcharts error #15: www.highcharts.com/errors/15 errors in thousands (mostly 80k +), which is hanging the browser.
What could be the issue and how can I get rid of it and increase performance? Sharing a plunker which has code and relatively small number of errors.
Note: I am using Highstock JS v2.1.5
There are two problems with this code:
First thing you need to sort the series in ascending order of X. I did not want to debug your code on how do you construct your data so I added a simple loop in the end to sort everything.
for (var i in seriesData) {
seriesData[i].data.sort(function(a, b) {
if (a.x > b.x) {
return 1;
}
if (b.x > a.x) {
return -1;
}
return 0;
});
}
The other problem is that the data array contains in correct data because of this line
if (task.intervals[j + 1]) {
item.data.push([(interval.to + task.intervals[j + 1].from) / 2, null]);
}
so I changed it to this
// add a null value between intervals
if (task.intervals[j + 1]) {
item.data.push({
task_id: interval.task_id,
x: (interval.to + task.intervals[j + 1].from) / 2,
y: null,
from: (interval.to + task.intervals[j + 1].from) / 2,
to: (interval.to + task.intervals[j + 1].from) / 2
});
}

Please read this link to improve highcharts performance. A few months ago Highcharts released boost.js to improve chart performance with millions of data points.
I'm trying to load data into a jqplot chart via variable, but it's only displaying the first value. I'm lost at to why is doing this.
JavaScript:
$(document).ready(function () {
var sin = [[20, 10, 0, 10, 15, 25, 35, 50, 48, 45, 35, 30, 15, 10]];
var plot = $.plot($(".chart"),
[{ data: sin, label: "sin(x)", color: "#ee7951" }], {
series: {
lines: { show: true },
points: { show: true }
},
grid: { hoverable: true, clickable: true },
yaxis: { min: 0, max: 60 }
});
var previousPoint = null;
$(".chart").bind("plothover", function (event, pos, item) {
if (item) {
if (previousPoint != item.dataIndex) {
previousPoint = item.dataIndex;
$('#tooltip').fadeOut(200, function () {
$(this).remove();
});
var x = item.datapoint[0].toFixed(2),
y = item.datapoint[1].toFixed(2);
maruti.flot_tooltip(item.pageX, item.pageY, item.series.label + " of " + x + " = " + y);
}
} else {
$('#tooltip').fadeOut(200, function () {
$(this).remove();
});
previousPoint = null;
}
});
});
maruti = {
flot_tooltip: function (x, y, contents) {
$('<div id="tooltip">' + contents + '</div>').css({
top: y + 5,
left: x + 5
}).appendTo("body").fadeIn(200);
}
}
</script>
Ultimately, I would prefer to use JSON format data and use the first value for the chart and the second for the axis.
Data:
[["50.00","3/18/2015 2:00:00 PM"],["37.00","3/12/2015 3:42:44 PM"],["35.00","3/11/2015 3:42:44 PM"]]
Any recommendations or link to samples using this type of data would be greatly appreciated.
The string format was wrong. I ended up using Entity Framework.
So my code behind looks something like:
using (myEntities myEntitiesContainer = new myEntities())
{
var alldata = myEntitiesContainer.myData(id).ToList();
foreach (myData i in alldata)
{
if (alldata.IndexOf(i) == alldata.Count - 1)
{
sb.Append("['").Append(i.DateData.ToString("yyyy-MM-dd HH:mmtt")).Append("', ").Append(i.SomeData.ToString()).Append("]");
}
else
{
sb.Append("['").Append(i.DateData.ToString("yyyy-MM-dd HH:mmtt")).Append("', ").Append(i.SomeData.ToString()).Append("], ");
}
}
myReturnString = sb.ToString();
}
The return string:
[['2015-03-31 16:00PM', 30.00], ['2015-03-31 14:00PM', 40.00], ['2015-03-31 13:00PM', 50.00]]
The Javascript looks like:
var renderGraph = function () {
var plot
var line1 =
plot = $.jqplot('chart', [line1], {
axes: {
xaxis: {
renderer: $.jqplot.DateAxisRenderer,
tickOptions: { min: 0, formatString: '%b %#d' },
tickInterval: '1 day'
},
yaxis: {
tickOptions:{ formatString: '%d'}
}
},
highlighter: {
show: true,
yvalues: 1,
xvalues: 1,
formatString: 'Date: %s Level: %s'
},
cursor: {
show: false,
tooltipLocation: 'sw'
},
legend: {
show: false
}
});
}
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!
