I am displaying jqplot meter gauge inside modal window and I want to update it after every 5 seconds. I wrote the following code but it is not working
$(document).ready(function(){
s1 = [Math.floor(Math.random()*(401)+100)];
plot3 = $.jqplot('meter',[s1],{
seriesDefaults: {
renderer: $.jqplot.MeterGaugeRenderer,
rendererOptions: {
min: 100,
max: 500,
intervals:[200, 300, 400, 500],
intervalColors:['#66cc66', '#93b75f', '#E7E658', '#cc6666'],
smooth: true,
animation: {
show: true
}
}
}
});
$('a[href=\"#yw1_tab_3\"]').on('shown', function(e) {
if (plot3._drawCount === 0) {
plot3.replot();
}
});
windows.setInterval(function() { plot3.destroy();
s1 = [Math.floor(Math.random()*(401)+100)];
plot3.replot();
}, 5000);
});
How can I update meter gauge every 5 seconds without updating whole page?
here is the fix: JsFiddle link
$(document).ready(function () {
var s1 = [Math.floor(Math.random() * (401) + 100)];
var plot3 = $.jqplot('meter', [s1], {
seriesDefaults: {
renderer: $.jqplot.MeterGaugeRenderer,
rendererOptions: {
min: 100,
max: 500,
intervals: [200, 300, 400, 500],
intervalColors: ['#66cc66', '#93b75f', '#E7E658', '#cc6666'],
smooth: true,
animation: {
show: true
}
}
}
});
setInterval(function () {
s1 = [Math.floor(Math.random() * (401) + 100)];
plot3.series[0].data[0] = [1,s1]; //here is the fix to your code
plot3.replot();
}, 1000);
});

So I have a project where I am trying to update chart. in which 100 points to be displayed in each second.
For that I am trying this example from the Highcharts.
But the chart stops responding to such event.
The code:
jsfiddle
Highcharts.chart('container', {
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], true, true);
}, 10);
}
}
},
time: {
useUTC: false
},
title: {
text: 'Live random data'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
headerFormat: '<b>{series.name}</b><br/>',
pointFormat: '{point.x:%Y-%m-%d %H:%M:%S}<br/>{point.y:.2f}'
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Random data',
data: (function () {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -19; i <= 0; i += 1) {
data.push({
x: time + i * 1000,
y: Math.random()
});
}
return data;
}())
}]
});
You can set redraw parameter in addPoint method to false and call chart.redraw() at longer intervals:
chart: {
...,
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series[0],
chart = this;
setInterval(function() {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], false, true);
}, 10);
setInterval(function() {
chart.redraw();
}, 500);
}
}
}

API Reference:
https://api.highcharts.com/class-reference/Highcharts.Series#addPoint
https://api.highcharts.com/class-reference/Highcharts.Chart#redraw
In the combination of series with and without dynamic data,the series with dynamic data can be easily shifted but where as the other series which are not dynamic do not get shifted out completely.
I have reproduced the issue in the following link: https://jsfiddle.net/8uxepk21/
Here as you can see there are two series. The series with static data appears to be shifting but if you increase the size of the rang-selector,then the series with static data do not get shifted out of the chart completely but still stays unlike the other series.
Is there any option to shift data explicitly without using series.addpoint() method.
I have used series.data[0].remove() and it obviously works fine but when a new data has to arrive for the same series after some time,this remove() method would remove the arriving point aswell. Further if I provide any condition for the maximum points to be in series while shifting,even then it will cause performance issue.
EXPECTED RESULT: Both the series data have to be shifted completely irrespective of the data being static or dynamic.
// Create the chart
Highcharts.stockChart('container', {
chart: {

// set up the updating of the chart each second

var x = (new Date()).getTime(), // current time

To achieve it you can add points with null values to the second series. Check the code and demo posted below.
Code:
chart: {
events: {
load: function() {
var chart = this,
series1 = chart.series[0],
series2 = chart.series[1],
x, y;
setInterval(function() {
x = (new Date()).getTime();
y = Math.round(Math.random() * 100);
series1.addPoint([x, y], false, true);
series2.addPoint([x, null], false, true);
chart.redraw();
}, 2000);
}
}
}

I'm trying to draw a 3d box after a user has selected some data from the server.
When I put the highcharts inside of a js function, it throws some errors.
My code is:
Chart It<br/>
<div id="container" style="height: 400px"></div>
<script>
var chart;
function chart3d() {
// Give the points a 3D feel by adding a radial gradient
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) {

// Set up the chart
chart = new Highcharts.Chart({

// Add mouse events for rotation
$(chart.container).on('mousedown.hc touchstart.hc', function (eStart) {

var posX = eStart.pageX,
posY = eStart.pageY,
alpha = chart.options.chart.options3d.alpha,
beta = chart.options.chart.options3d.beta,
newAlpha,
newBeta,
sensitivity = 5; // lower is more sensitive
$(document).on({
'mousemove.hc touchdrag.hc': function (e) {
// Run beta
newBeta = beta + (posX - e.pageX) / sensitivity;
chart.options.chart.options3d.beta = newBeta;
// Run alpha
newAlpha = alpha + (e.pageY - posY) / sensitivity;
chart.options.chart.options3d.alpha = newAlpha;
chart.redraw(false);
},
'mouseup touchend': function () {
$(document).off('.hc');
}
});
});
}
</script>
This loads fine if I do not put it inside of the chart3d function. Is there a way to get this working. The error message I get is:

As they say:
Highcharts Error #13
Rendering div not found
This error occurs if the chart.renderTo option is misconfigured so that
Highcharts is unable to find the HTML element to render the chart in.
You don't have a div with the id=container at the time you are calling the method.

Here is the code in concern:
$(function() {
var chartData = [-5, 5, -10, -20];
var timeStamps = [];
var index = 1;
var pWidth = 25;
$('#b').click(function(){
timeStamps.push(new Date());
var buttonB = document.getElementById('b');
buttonB.disabled = true;
/* if(index == 1){
$('#container').highcharts().xAxis[0].labels.style = {"color":"#6D869F","fontWeight":"bold"};
}*/
if(index <= chartData.length){
$('#container').highcharts().series[0].remove();
$('#container').highcharts().addSeries({pointPlacement: 'on', data: [chartData[index - 1]],
pointWidth: pWidth});
$('#container').highcharts().xAxis[0].setCategories([index]);
setTimeout(function(){index++;}, 2000);
}
if(index < chartData.length){
setTimeout(function(){buttonB.disabled = false;}, 1500);
}else{
setTimeout(function(){buttonB.style.visibility="hidden";}, 1500);
}
if(index == chartData.length - 1){
setTimeout(function(){document.getElementById('b').innerHTML = 'Lasst Period';}, 1500);
}
console.log(timeStamps);
})
// $(document).ready(function () {
Highcharts.setOptions({
lang: {
decimalPoint: ','
},
});
$('#container').highcharts({
chart: {
type: 'column',
width: 170,
marginLeft: 74,
marginRight: 16,
marginBottom: 60
},
title: {
text: ''
},
colors: [
'#0000ff',
],
xAxis: {
title: {
text: ''
// offset: 23
},
gridLineWidth: 1,
startOnTick: true,
tickPixelInterval: 80,
categories: ['Filler'], // used only to make sure that the x-axis of the two charts
// are aligned, not shown on the chart via setting the font color to white
min:0,
max:0,
labels: {
style: {
color: 'white'
}
}
},
yAxis: {
title: {
text: 'Value'
},
min: -20,
max: 20,
tickPixelInterval: 40
},
plotOptions: {
series: {
animation: {
duration: 1000
}
}
},
credits: {

},
tooltip: {

return Highcharts.numberFormat(this.y, 2) + '%';
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
data: [],
pointWidth: pWidth
}]
});
// });
});
I want that the x-axis has no label when the page is loaded (The reason why I added in a filler text with white font is due to the fact that I don't want the size of the chart change upon click of a button). And upon the click of button, the label should be consecutively 1, 2, 3, 4...
Is there anyway around it except for setting marginBottom (which is not very precise)?
You may use .css() method for changing fill color of your text label.
Here you can find information about this method:
http://api.highcharts.com/highcharts#Element.css
Highcharts.each($('#container').highcharts().xAxis[0].labelGroup.element.children, function(p, i) {
$(p).css({
fill: 'red'
});
});
And here you can find simple example how it can work:

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
}
});
}
