I am in the process of moving from a built in graph library to HighStock.
I have to comply to crasy implementations. So at the end I got this configuration :
$(function() {
chart = new Highcharts.StockChart({
chart : {
renderTo : 'div_#divid#'
},
rangeSelector : {
selected : 0,
buttons: [{
type: 'day',
count: 7,
text: '7j'
}, {
type: 'day',
count: 15,
text: '15j'
}, {
type: 'day',
count: 30,
text: '30j'
}, {
type: 'all',
text: 'Tous'
}]
},
series : [{
type : 'column',
name : 'valeur',
data : data,
tooltip: {
valueDecimals: 2
}
}]
});
});
Here is the fiddled version.
I don't get whats wrong with my data. (but I think I did correctly the conversion for the dates.)
[[1362355200000,672],[1362441600000,9764],[1362528000000,9839],[1362614400000,9906], [1362700800000,9973],[1362787200000,9906],[1362873600000,10592],[1362960000000,11236], [1363046400000,13233],[1363132800000,0],[1363219200000,0],[1363305600000,0],[1363392000000,0],[1363478400000,0],[1363564800000,0],[1363651200000,0],[1363737600000,0],[1363824000000,0],[1363910400000,0],[1363996800000,0],[1364083200000,0],[1364169600000,0],[1364256000000,0],[1364342400000,0],[1364428800000,0],[1364515200000,0],[1364601600000,0],[1364688000000,0],[1364770800000,0],[1364857200000,0],[1364943600000,0],[1365030000000,0],[1365116400000,0],[1365202800000,0],[1365289200000,0],[1365375600000,0],[1365462000000,0],[1365548400000,0],[1365634800000,0],[1365721200000,0],[1365807600000,0],[1365894000000,0],[1365980400000,0],[1366066800000,0],[1366153200000,0],[1366239600000,0],[1366326000000,0],[1366412400000,0],[1366498800000,0],[1366585200000,0],[1366671600000,0],[1366758000000,0],[1366844400000,0],[1366930800000,0],[1367017200000,0],[1367103600000,0],[1367190000000,0],[1367276400000,0],[1367362800000,0],[1367449200000,5490]]
Thanks for your help.
I'm not sure, the problem is that you can't see the chart? That's cause your data contains '
Check the jsFiddle: http://jsfiddle.net/SqZY2/1/
You have this:
data = '[[1362355200000,672],[1362441600000,9764],[1367103600000,0],[1367190000000,0],[1367276400000,0],[1367362800000,0],[1367449200000,5490]]';
Must be this:
data = [[1362355200000,672],[1362441600000,9764],[1362528000000,9839],[1362614400000,9906],[1367103600000,0],[1367190000000,0],[1367276400000,0],[1367362800000,0],[1367449200000,5490]];

I am trying to create a lollipop chart where some values are negative, and some are positive, either side of zero, like this:
image
However the chart seemingly only allows the marker to be on the "high" end of the chart. Is there a way to control which end has the marker ?
I'm using these chart options:
chartOptions: {
chart: {
type: 'dumbbell',
inverted: true
},
title: {
text: 'lollipop chart'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'value'
}
},
series: [{
name: 'value',
data: [{
name: 'a',
low:0,
high:13,
}, {
name: 'b',
low:0,
high:26,
},{
name: 'c',
low:-43,
high:0
},{
name: 'd',
low:-83,
high:0
},{
name: 'e',
low:0,
high:113
}]
}]
}
The series which should be used in this case is a lollipop, but it seems that the array of objects configuration doesn't work. I reported it on the Highcharts Github issue channel, where you can follow this thread: https://github.com/highcharts/highcharts/issues/13202
As a solution in the dumbell series I suggest to find those graphics in the render callback and hide them.
Demo: https://jsfiddle.net/BlackLabel/3o7acsbt/
events: {
render() {
let chart = this;
chart.series[0].points.forEach(p => {
if (p.low >= 0){
p.lowerGraphic.hide()
} else {
p.upperGraphic.hide()
}
})
}
}
API: https://api.highcharts.com/highcharts/chart.events.render
EDIT
Under the GitHub link, the workaround showed up. Please check it, maybe will be fit better to your requirement.
I'm trying to get this chart to only be dotted for the last month:
chart_data = [[1496275200000, 981], [1498867200000, 1089], [1501545600000, 1595], [1504224000000, 1296], [1506816000000, 1678], [1509494400000, 1879], [1512086400000, 2028], [1514764800000, 1885], [1517443200000, 1366], [1519862400000, 1558], [1522540800000, 1636], [1525132800000, 2438], [1527811200000, 2899], [1530403200000, 2521], [1533081600000, 2879], [1535760000000, 1702]]
Highcharts.chart('container', {

(This highcharts code is basically the same as: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/series/color-zones-dashstyle-dot/ from the highcharts documentation, just with my time-series data instead.
However, it makes the entire chart turn dotted instead of just the last bit. Any ideas why? I can't seem to fix this.
You need the real value not the starting index like that :
dottedStartIndex = chart_data[chart_data.length - 2][0];
Highcharts.chart('container', {
...
zones: [{
value: dottedStartIndex
}, {
dashStyle: 'dot'
}]

I made a barchart with dates. Currently, to remove the dates, you must click on the dates in the legend. I wish delete multiple dates at once.
Let's take an example. My dates range from 1960 to 2015. If I would have on my chart the dates from 2000 to 2005, so I would like that if you click on 1960 and 1999, then all the dates between are deleted / hidden. It goes faster when many dates.
How to do ?
Here is my code :
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},

Rather than having each year as its own series, I would recommend that you place the years as the values in your x-axis (as categories) and then use Highcharts' native zoom function to allow users to select a certain date range.
I've updated your fiddle with some changes, which I explain below: https://jsfiddle.net/brightmatrix/hr28s27L/
First, in your chart option, I added zoomType: 'x' to allow users to use their mouse to zoom in on specific years. The value x means they can only zoom horizontally (across), which makes for a "cleaner" interaction.
chart: {
type: 'column',
zoomType: 'x'
},
Second, I updated your x-axis with the years as the categories/values:
xAxis: {
categories: ['2004','2005','2006','2007','2008','2009','2010','2011','2012','2013','2014','2015','2016']
},
Lastly, I updated your series to show just the data points, which are then plotted on the y-axis:
series: [{
name: 'data by year',
data: [49.9,83.6,48.9,69.1,83.6,40.9,69.9,83,28.9,40.9,81.6,24.9,46.4]
}]
Here is what happens when a user clicks and drags their mouse cursor:
The shaded box is what they are selecting. Once they release the cursor, the chart will automatically adjust to show only what they chose. A "Reset Zoom" button will appear at the top right to allow them to go back to all years:
Update (July 19, 2016): I did some research on adding a simple slider element to this chart that allows users to choose from a range of years.
An updated version of my fiddle that shows this example chart with sliders can be found here: https://jsfiddle.net/brightmatrix/uvat8u05/.
The code to handle the sliders is shown below. I discovered that explicitly setting the slider values to integers using the parseInt() function solved a couple of problems:
You can correctly compare the slider values to make sure users can't choose an end year that is earlier than the start year.
The setExtremes() function correctly shows a single year when users choose the same start and end year.
All x-axis labels are shown at all times. Before I added parseInt(), some labels disappeared when users chose different values in the sliders.
Please be sure to read the comments I've left in both the HTML and Javascript panes, as I've included additional details on why I made certain code decisions.
// on change handler for both sliders
$('.mySlider').bind('change', function(e) {
e.preventDefault();
var chart = $('#container').highcharts();
// convert the slider values to integers to make sure setExtremes() works as expected
var slider1Val = parseInt($('input[name="slider1"]').val());
var slider2Val = parseInt($('input[name="slider2"]').val());
if (slider2Val < slider1Val) {
// warn the user if they try to choose an end year that is later than the start year
alert("You can't choose an end year that is earlier than your start year.");
} else {
// use setExtremes to set the x-axis ranges based on the values in the sliders
chart.xAxis[0].setExtremes(slider1Val, slider2Val);
}
});
I hope this information is helpful for you.
I created a highstock spline graph with half an hour interval data. The graph displays on "1 month,3 month" selectors, disappear on "all" selector. There are too many data points which could be the problem; but my other hourly dataset has even more data and works just fine.
See all the code in jsFiddle:https://jsfiddle.net/gbr1v9yu/8/

$('#chart-A').highcharts('StockChart', {

// },
yAxis: {

formatter: function () {
return this.value + ' m';
}
}

Can anyone help me out? Thanks a lot.
I am generating a Project Cumulative Flow Chart, which is based on the Project name that I fetch using a "find," however I can't get it working.
Here is the Problem:
1) The "Find" in my code is just fetching one kind of project name, "FE," however, I have a lot of other Project name such as FE, BE, VisualRF, etc. I am not sure what's going on
2) I return this to "storeConfig" inside the chart and then I want try to give "Name" to the "stateFieldName." This is not working! I don't see any graph at all.
Here is the code.
_chart2: function() {
var projectName = this.getContext().getProject()._refObjectName;
console.log("========");
console.log(projectName); <<<<<<<<<< This always prints one name'FE' (My project name are FE, BE, etc)
this.chart = {
xtype: 'rallychart',
storeType: 'Rally.data.lookback.SnapshotStore',
storeConfig: this._getStoreForChart2(),
calculatorType: 'Rally.example.CFDCalculator',
calculatorConfig: {
stateFieldName: this.getContext().getProject()._refObjectName, <<<<< I think usage is not fetching name of all projects
stateFieldValues: ['FE','BE','VisualRF']
},
width: 1000,
height: 600,
chartConfig: this._getChart2Config()
};
this.chartContainer.add(this.chart);
},
_getStoreForChart2: function() {
var obj1 = {
find: {
_TypeHierarchy: { '$in' : [ 'Defect' ] },
Children: null,
_ProjectHierarchy: this.getContext().getProject().ObjectID,
_ValidFrom: {'$gt': Rally.util.DateTime.toIsoString(Rally.util.DateTime.add(new Date(), 'day', -30)) },
State: "Open",
},
fetch: ['Severity','Project','ObjectID','FormattedID'],
hydrate: ['Severity','Project','ObjectID','FormattedID'],
sort: {
_ValidFrom: 1
},
context: this.getContext().getDataContext(),
limit: Infinity,
val: this.Name,
};
return obj1;
},
Though this should not matter but here is the code for the high chart function I am calling above
_getChart2Config: function() {
console.log("starting chart config");
return {
chart: {
zoomType: 'xy'
},
title: {
text: 'Chart2'
},
xAxis: {
tickmarkPlacement: 'on',
tickInterval: 20,
title: {
text: 'Date'
}
},
yAxis: [
{
title: {
text: 'Count'
}
}
],
plotOptions: {
series: {
marker: {
enabled: false
}
},
area: {
stacking: 'normal'
}
}
};
},
Down below you can see 'FE' getting printed:
Thanks a lot!

stateFieldName is the field which is used to calculate the CFD- usually ScheduleState or a custom dropdown field like KanbanState that captures your process. The stateFieldValues should be the values of that field (Defined, In-Progress, Accepted, Completed, etc.) This doesn't deal with projects at all. Definitely remember to include that field in your hydrate and fetch as well.
