When I export (click the hamburger and click export SVG) the Data-Labels display fine.
When I use my highcharts-export-server they do not:

Do you mean that series labels are not visible on an exported image when using node export server (https://github.com/highcharts/node-export-server) on your side? If so, the reason behind it is because the series-label script (https://code.highcharts.com/modules/series-label.js) isn't included among other additional scripts (such as xrange) in the build.js file. All you need to do is to add the following:
'{{version}}/modules/series-label.js': 1
inside the cdnScriptsOptional array and run node build.js. For more information you can visit repo of the exporting server (https://github.com/highcharts/node-export-server).

I have the following code for the node.js high-Charts export-server the legend is showing but the label formatted is not applied and the function is not executed also
I have tried the load function also and it is not working, I tried custom HTML and it is now showing also
let chartDetails = {
type: "png",
options: {
chart: {
type: "pie",
showInLegend: true,
dataLabels: {
enabled: false
}
},
title: {
align: 'left',
floating: false,
text: 'Main Title',
style: {
fontSize: '24px'
}
},
subtitle: {
verticalAlign: 'middle',
align: 'center',
floating: false,
text: '<b>300</b><br>Total Issues',
style: {
fontSize: '30px'
}
},
plotOptions: {
pie: {
innerSize: '70%',
shadow: false,
showInLegend: true,
dataLabels: {

}
}
},
legend: {
enabled: true,
floating: true,
borderWidth: 0,
align: 'right',
layout: 'vertical',
verticalAlign: 'middle',
useHTML: true,
labelFormatter: function () {
console.log("this: is equal to ");
console.log(this);
return 'custom word';
}
}
,
series: [
{
data: [
{
name: "a",
y: 100
},
{
name: "b",
y: 20
},
{
name: "c",
y: 50
}
]
}
]
}
};
I expected 'custom word' instead 'a','b','c' is showing
It seems when using node-export-server as a module callback functions are not supported. Check this thread on the module github: https://github.com/highcharts/node-export-server/issues/122.
As a workaround, you can use labelFormat property instead of labelFormatter:
legend: {
enabled: true,
floating: true,
borderWidth: 0,
align: 'right',
layout: 'vertical',
verticalAlign: 'middle',
useHTML: true,
labelFormat: "custom word"
}
i am using highcharts-export-server for export charts and send it to Email in PDF format
while i am trying to export that in localy it was working fine, but on live server when i am trying to export all the charts data-labels disappear.
this is the image from which was exporting from live server.
and here is the image which was exporting locally.
Here is my Code
exports.getPieChartImg = (seriesData, xOrLength, innersize, showLegend, width, height) => {
var chartOpts = {
chart: {
type: 'pie',
width: width,
height: height,
},
plotOptions: {
pie: {
innerSize: innersize || 80,
depth: 25,
allowPointSelect: true,
dataLabels: {
enabled: false,
format: '<b>{point.name}</b>: {point.percentage:.2f} %'
},
showInLegend: showLegend || false,
},
series: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: '#6f6f6f',
format: '{point.percentage:.2f}',
crop: false,
overflow: "none",
},
pointWidth: 30,
}
},
legend: {
labelFormat: '<b>{name}</b> ({percentage:.2f})%',
useHTML: true,
},
series: [{
data: seriesData
}]
};
var exportSettings = generateExportSettings(chartOpts, 'Pie');
return generateBase64Chart(exportSettings)
}
function generateExportSettings(chartOpts, constr) {
return {
// b64: true,
instr: JSON.stringify(chartOpts),
noDownload: true,
constr,
globalOptions: {
colors: ['#3BB9DA', '#0F89A8', '#0B8F8B', '#1DB1AD', '#68E3DF', '#FFB469', '#F58B1F', '#D16900', '#FC3C3C', '#FF6666', '#FC8D8D', '#FCC0C0'],
lang: {
thousandsSep: ','
}
},
scale: false,
styledMode: false,
type: "image/png",
width: false,
};
}
function generateBase64Chart(exportSettings) {
return new Promise((resolve, reject) => {
highchartsExporter.export(exportSettings, function (err, res) {
if (err) {
return reject({
code: '1',
err,
msg: 'Error in stock chart',
exportSettings
})
}
return resolve({
code: '0',
msg: 'success',
data: 'data:image/png;base64,' + res.data,
})
});
})
}
remove node_module and reInstall it again.
and if not installed libfontconfig then install 'sudo apt-get install libfontconfig'
I'm trying to create a container that has four items, and what I need is the container to be the one that scroll instead of each individual item, also I want every item to have it's own height so if the four items are bigger than the screen the user can scroll down through the container to see the other items info...
JSFiddle:
http://jsfiddle.net/martuanez/7GV3b/
My code:
var store = {
type: 'store',
fields: ['label', 'value'],
data: [{
label: 'label',
value: 'value',
}, {
label: 'label',
value: 'value',
}, {
label: 'label',
value: 'value',
},
]
};
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: ('SF' || 'SenchaFiddle'),
launch: function () {
Ext.define('MyApp.view.Contacts.ContactsDetailsView', {
xtype: 'ContactsDetailsView',
extend: 'Ext.Container',
config: {
layout: {
type: 'vbox',
padding: 3
},
defaults: {
scrollable: {
direction: 'horizontal',
directionLock: true
},
height: 500,
layout: 'fit'
},
scrollable: 'vertical',
itemCls: 'details-list-container',
items: [{
xtype: 'dataview', //add xtype
itemId: 'detailItem',
loadingText: 'Loading keys...',
emptyText: '<div>No keys found.</div>',
store: store,
onItemDisclosure: false,
itemTpl: '<br/>item 1:<br/> {label}<br/>{value}<br/><br/>',
itemCls: 'details-list',
selectedItemCls: '',
disableSelection: true,
pressedCls: ''
}, {
xtype: 'list',
itemId: 'detailKeys',
store: store,
loadingText: 'Loading keys...',
emptyText: '<div>No keys found.</div>',
onItemDisclosure: false,
itemTpl: 'item 2: {label}{value}<br/>',
itemCls: 'details-list',
selectedItemCls: '',
disableSelection: true,
pressedCls: ''
}, {
xtype: 'list', //add xtype
itemId: 'detailuserdefs',
store: store,
loadingText: 'Loading userdefs...',
onItemDisclosure: false,
itemTpl: 'item 3: {label}{value}<br/>',
itemCls: 'details-list',
selectedItemCls: '',
disableSelection: true,
pressedCls: ''
}, {
xtype: 'list',
itemId: 'detailOthers',
store: store,
loadingText: 'Loading userdefs...',
onItemDisclosure: true,
itemTpl: 'item 4: {label}{value}<br/>',
itemCls: 'details-list'
}
]
}
});
Ext.Viewport.add(Ext.create('MyApp.view.Contacts.ContactsDetailsView'));
}
});
I´ve finally make it work, i set scrollable to false in the defaults section of the container and a height on the child items.
One thing that happened is that when setting scrollable to false in the childs, not in the defaults, sencha didn't recognize the height, this is a bug that they claim they have fixed already, actual version by the time i'm writting this 2.2, version i'm working on 2.1.1
Note: I also managed to set dinamic heights on each item, i did this by setting it apart and adding the items later by doing myContainer.add(itemWithDinamicHeight);
;)
Cheers!
using jqPlot, is it possible to limit the point labels to just one series? See screenshot below! What I would like displayed is just the values above the "Actual" bar. The "mean" and "Planned" should'nt display!
Thanks!
Here's my code
<script type="text/javascript">
$(document).ready(function () {
$.jqplot.config.enablePlugins = true;
var trendline = [60000, 70000, 110000, 80000];
var planned = [70000, 90000, 120000, 100000,];
var actual = [80000, 80000, 150000, 120000];
var xAxis = ['Jan', 'Feb', 'Mar', 'Apr'];
$(function() {
$.jqplot('chartDiv', [planned, actual, trendline], BarChart());
});
function BarChart()
{
var optionsObj = {
title: '',
axes: {
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
ticks: xAxis,
},
yaxis: {
tickOptions: { showMark: false, formatString: "%'d" },
},
},
legend: {
show: true,
},
grid: {
borderColor: "#dad5d1",
background: "#dad5d1",
drawGridlines: false,
shadow: false
},
series: [
{label:'Planned',renderer:$.jqplot.BarRenderer},
{label: 'Actual',renderer:$.jqplot.BarRenderer},
{label: 'Mean',
pointLabels: {
show: true,
},
renderer:$.jqplot.LineRenderer,
lineWidth:4,
markerOptions:{
color: "#d87d12",
size:12,
}}
],
seriesColors: [ "#ada195", "#4a4541", "#ff9619"],
seriesDefaults:{
shadow: false,
rendererOptions:{
barPadding: 0,
barMargin: 10,
barWidth: 25
}
},
};
return optionsObj;
}
});
</script>
This actually looks like a bug in the point labels plugin. You can work around it by disabling the values in the seriesDefault (show:false) and then turning them on for the series you desire:
series: [
{label:'Planned',renderer:$.jqplot.BarRenderer},
{label: 'Actual',renderer:$.jqplot.BarRenderer},
{label: 'Mean',
pointLabels: {
show: true,
},
renderer:$.jqplot.LineRenderer,
lineWidth:4,
markerOptions:{
color: "#d87d12",
size:12,
}}
],
seriesDefaults:{
pointLabels:{show:false},
shadow: false,
rendererOptions:{
barPadding: 0,
barMargin: 10,
barWidth: 25
}
},
I have a panel which is fullscreen;
PortalDashboard.views.Dashboardcard = Ext.extend(Ext.Panel, {
fullscreen: true,
title: 'Dashboard',
html: '',
cls: 'card5',
iconCls: 'team',
layout: Ext.Viewport.orientation == 'landscape' ? {
type: 'hbox',
pack: 'center',
align: 'stretch'
} : {
type: 'vbox',
align: 'stretch',
pack: 'center'
},
monitorOrientation: true,
listeners: {
orientationchange : this.onOrientationChange,
},
styleHtmlContent: false,
initComponent: function () {
Ext.apply(this, {
items: [
{
xtype: 'dashboardbox',
items: [rep1, rep2, rep3]
}, {
xtype: 'dashboardbox',
items: [rep4, rep5, rep6]
}]
});
PortalDashboard.views.Dashboardcard.superclass.initComponent.apply(this, arguments);
}
})
So the panel has a hbox layout with 2 child panels. The child panels actually take up the full amount of horizontal space, but not vertically.
I can set the min-height in the css, which gets respected on in chrome and safari on my pc... but the ipad ignores it.
The child panels are defined as;
PortalDashboard.views.DashboxBox = Ext.extend(Ext.Panel, {
cls: 'dashbox',
monitorOrientation: true,
listeners: {
orientationchange : this.onOrientationChange,
},
layout: Ext.Viewport.orientation == 'landscape' ? {
type: 'vbox',
align: 'stretch',
pack: 'center'
} : {
type: 'hbox',
align: 'stretch',
pack: 'center'
},
defaults: {
flex: 1
}
});
Ext.reg('dashboardbox', PortalDashboard.views.DashboxBox);
I've had this before with a TabPanel parent of some sub panels. Try layout: 'fit' in your parent panel. (Although I'm not sure if adding it to your current list of layout options will work or if it needs to be set by itself.)
