I display correctly a funnel dataviz kendo-Ui chart, it works great except when my dataItem is 0
I want it to display in my label so I made a custom label:
seriesDefaults: {
labels: {
visible: true,
background: "transparent",
color:"white",
format: "N0",
template: "#= dataItem.type # - #= dataItem.value#"
},
dynamicSlope: false,
dynamicHeight: false
},
I get my data from a Json call which return 0.
How should I do to make my funnel display the label even if the dataItem.value = 0?
I ended by doing quick and dirty fix, i replaced 0 by 0.000001 and rounding at display it's dirty but it works.

I am currently working on a project for my company, where I need to plot highstock charts, which show energy-data of our main buildings.
Since it is live data, new datapoints come per Websocket every few-or-so seconds. However, the graph should only show one datapoint every hour. I wanted to clear this with the highstock dataGrouping, but it does not really work. It groups the points yes, but it still shows the „transmission“, the graph-line, between them. Thus making the whole graph completely irreadable.
In an other Version of the project, the graph only shows the latest datapoint of each group (as specified in the „approximate“ object in the chart options), but also does not start a new group after the chosen Interval runs through.
I've been sitting on this problem for about 3 days now and have not found any proper completely working solution yet.
Unfortunately, due company policy and due to hooks and components necessary, which are only used here in the company, I'm not able to give you a jsfilddle or similar, even though I'd really love to. What I can do is give you the config, mabye you find something wrong there?
const options = {
plotOptions: {
series: {
dataGrouping: {
anchor: 'end',
approximation: function (groupData: unknown[]) {
return groupData[groupData.length - 1];
},
enabled: true,
forced: true,
units: [['second', [15]]],
},
marker: {
enabled: false,
radius: 2.5,
},
pointInterval: minutesToMilliseconds(30),
pointStart: currentWeekTraversed?.[0]?.[0],
},
},
}
This would be the plotOptions.
If you need any more information, let me know. I'll see then, what and how I can send it to you.
Thank you for helping. ^^
This is example how dataGrouping works with live data,
try to recreate your case in addition or use another demo from official Highcharts React wrapper page.
rangeSelector: {
allButtonsEnabled: true,
buttons: [{
type: 'minute',
count: 15,
text: '15S',
preserveDataGrouping: true,
dataGrouping: {
forced: true,
units: [
['second', [15]]
]
}
}, {
type: 'hour',
count: 1,
text: '1M',
preserveDataGrouping: true,
dataGrouping: {
forced: true,
units: [
['minute', [1]]
]
}
}
},

I have an AmChart that I want to appear in an md-dialog. It's passed a JSON dataProvider and yet nothing appears.
dialog.tmpl.html:
<md-dialog aria-label="Project Zone Chart">
<md-toolbar>
<div class="md-toolbar-tools">
<h2>Project Zone Chart</h2>
<span flex></span>
<md-button class="md-icon-button" ng-click="closeDialog()">
<md-icon aria-label="Close dialog">close</md-icon>
</md-button>
</div>
</md-toolbar>
<md-dialog-content>
<p><div id="projZoneChart" style="width: 100%; height: auto;"></div></p>
</md-dialog-content>
</md-dialog>
controller.js:
var projZoneChartOps = {
type: "serial",
valueAxes: [{
minorGridAlpha: 0.08,
minorGridEnabled: true,
position: "top",
gridAlpha: 0,
precision: 0
}],
startDuration: 1,
graphs: [{
type: "column",
fillAlphas: 1,
lineAlpha: 0,
valueField: "value",
colorField: "color",
lineAlpha: 0
}],
rotate: true,
categoryField: "metric",
categoryAxis: {
gridPosition: "start",
parseDates: false,
gridAlpha: 0
}
};
createChart($scope.chartdata, projZoneChartOps);
function createChart(chartData, chartOps){
$scope.projZoneChart = AmCharts.makeChart("projZoneChart", chartOps);
$scope.projZoneChart.dataProvider = chartData;
However nothing appears in the dialog at all. Is there a problem with my chartOps?
Note: the chartData variable is a JSON object with two fields, startOfWeek (supposed to be the x-axis) and metric (supposed to be the y-axis)
There are a few issues/comments:
1) Why aren't you assigning the data to the chartOps object before calling makeChart?
chartOps.dataProvider = chartData;
$scope.projZoneChart = AmCharts.makeChart("projZoneChart", chartOps);
This will actually make the chart start off with your data. The way you're doing it will require that you call validateData() on your chart object after manually setting the dataProvider, which is unnecessary overhead compared to including it directly in makeChart.
$scope.projZoneChart = AmCharts.makeChart("projZoneChart", chartOps);
$scope.projZoneChart.dataProvider = chartData;
$scope.projZoneChart.validateData(); //required if you're doing it this way but unneccessary overhead compared to simply including it inside of makeChart directly as you're essentially remaking the chart after you create it for the sake of rendering your data.
2) Make sure your *field properties match. startOfWeek isn't mentioned in your chart config at all, even though you're saying it's in your JSON data. Your valueField is set to "value" - you might want to set it to "startOfWeek" instead unless you're modifying your JSON object somewhere else.
3) Displaying charts inside a modal or other dynamic/hidden elements typically require that you call the chart object's invalidateSize method when the modal/tab/etc containing the chart is visible so that it will render correctly. You'll want to check for whatever event md-dialog offers to determine when it is visible before calling $scope.projZoneChart.invalidateSize().
I'm quite new to Highcharts and the documentation is pretty huge for me to solve my little big problem.
I'm working on app for runners and want to display running pace on chart in minutes:seconds by kilometer or mile, in format like 05:30, which means pace 5 minutes and 30 seconds pre kilometer or mile.
My current (and not working) code is here:
Highcharts.chart('container', {
yAxis: {
type: 'datetime',
categories: ['03:30','04:00','04:30','05:00','05:30','06:00','06:30','07:00','07:30','08:00','08:30'],
labels: { format: '{value:%H:%M}'}
},
xAxis: {
categories: ['2018-01-01', '2018-05-01', '2018-10-01']
},
series: [{
data: ['05:00', '06:00' , '06:30'],
dataLabels: { format: '{value:%H:%M}'}
}],
legend: {layout: 'vertical',align: 'right',verticalAlign: 'middle'},
plotOptions: {series: {label: {connectorAllowed: false},pointStart: 0}},
responsive: {rules: [{condition: {maxWidth: 1000},chartOptions: {legend: {layout: 'horizontal',align: 'center',verticalAlign: 'bottom'}}}]}
});
Currently the line in chart is not appearing. Can anybody repair my code to work correctly? Thanks.
Data needs to be numbers, not string values. If you look in console, you will most likely have Error 14 telling you this.
Changing your data to milliseconds (the format needed for highcharts to understand time) will work, like this:
data: [5 * 3600 * 1000, 06 * 3600 * 1000, 6.5 * 3600 * 1000],
Working example: https://jsfiddle.net/ewolden/55bk99ke/2/
If you want to fix the tooltip in the above example, you just need to format it the same way you format the yAxis labels. Like this:
tooltip: {
pointFormat: '{point.y:%H:%M}'
},

I am trying to make a grid groupable on columns field but the columns are object.
{
Gestionnaire :
{ id: 4, nom:'nomgestionnaire'},
{..},
..
}
I have success for sortable:
columns: [
field: "Gestionnaire"
title: "Gestionnaire"
sortable:
compare: (a,b) =>
#compareColumnFields(a.Gestionnaire.Nom, b.Gestionnaire.Nom)
]
with #compareColumnFields function is :
if a is b
return 0
else if a > b
return 1
else
return -1
and for groupable?
groupable : ...
I think you're wanting to allow the user to actively group columns.
In that case, all you need is:
groupable: true
in the main structure of the grid.
For example:
$('#grid').kendoGrid({
columns: [
{
fields: "Guestionaire",
title: "Guestionaire",
sortable:
compare: (a,b) =>
#compareColumnFields(a.Guestionaire.Nom, b.Guestionaire.Nom)
},
{...placeholder for other columns...}
],
groupable: true
});
Kendo has a sample of this at http://dojo.telerik.com/ejehe
Ignore the SelectRow and Expand/Collapse stuff and that ought to be the same as what you're trying to accomplish.
For those in the same situation as me , I completely change solution. Instead of making me a function that returns true and false , it giving it the object in full, I just give the string .
For my example I give directly a.Gestionnaire.Nom and b.Gestionnaire.Nom, and THEN you can call :
groupable: true
In fact it was obvious.
I need some help related with jqPlot pie-chart value. Using the following data-set:
['XX01',77.28], ['XX02',3.28], ['XX03',3.31], ['XX04',2.42], ['XX05',2.4],
['XX06',1.61], ['XX07',2.45], ['XX08',1.69], ['XX09',2.18], ['XX10',1.6],
['XX11',1.78]
and this jqPlot option script:
seriesDefaults: {
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
showDataLabels: true,
dataLabels: 'value',
dataLabelFormatString: '%.2f%%',
dataLabelPositionFactor: 1.2,
shadow: false,
sliceMargin: 3
},
}
the result is not showing all the available values. see the snapshot.
Can somebody help me about this? Waiting for any solution here... thanks!
Thank you for the response, Nandu.
I just figured it out yesterday, there is plugin's option for the data label, it is called dataLabelThreshold - jqPlot documentation. By default the value is 3, which mean that for any value below 3 won't be displayed. So the solutions just as simple as define the new threshold.
See this FIDDLE
$.jqplot('pieChart', [[['XX01',7.28], ['XX02',3.28], ['XX03',3.31], ['XX04',2.42], ['XX05',2.4],
['XX06',1.61], ['XX07',2.45], ['XX08',1.69], ['XX09',2.18], ['XX10',1.6],
['XX11',1.78]]],
{
seriesDefaults: {
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
showDataLabels: true,
dataLabels: 'value',
dataLabelFormatString: '%.2f%%',
dataLabelPositionFactor: 1.2,
shadow: false,
sliceMargin: 3
},
}
});
I think it is due to your data.I changed the first data from 77.28 to 7.28.It works fine.
