So close! Why on earth is this code not working? On the first slide it gets it's new value (2) but keeps the same message "terrible". Then after that works fine, except the messages are all stepped back one position. It's driving me mad!
var messages = {
1: "terrible",
2: "okay",
3: "better",
4: "great",
5: "super!"
};
initialValue = 1
var messageUpdate = function(event, ui) {
var curValue = ui.value || initialValue;
var message = '<div id="out">' + (messages[$('#slider').slider('value')]) + '</div>';
$('.ui-slider-handle').html(message);
}
$("#slider").slider({
value: initialValue,
min: 1,
max: 5,
step: 1,
create: messageUpdate,
slide: messageUpdate
});
Of course, as soon as you see it on here in black and white it becomes obvious:
var curValue = ui.value || initialValue;
var message = '<div id="out">' + (messages[curValue]) + '</div>';
I was not using my own code!

Here is my code as below, Please help me to find out solution for add highlight on those dates which I particularly disabled and Sundays.
And Do not want to highlight disabled previous dates from current date.
In this how can add highlights on particular dates which I disabled.
$(document).ready(function(){
jQuery(function() {
var blockedDates = ["12/20/2022", "12/28/2022", "12/24/2022", "12/19/2022"];
var dateFormat = "yy-mm-dd";
$( "#datepicker" ).datepicker({
dateFormat:'yy-mm-dd',
minDate: 0,
daysOfWeekDisabled: [0, 6],
onSelect: function(dateStr) {
var _frmdate = $.trim($(this).val());
jQuery("#blockModalDateItem").modal("show");
jQuery("#bk_blockdt").val(_frmdate);
jQuery(".status_msg").html("");
},
beforeShowDay: function(date){
show = true;
if(date.getDay() == 0 ){show = false;}
for (var i = 0; i < blockedDates.length; i++) {
if (new Date(blockedDates[i]).toString() == date.toString()) {show = false;}
}
var display = [show,'',(show)?'':'Block Settlement Date']; //Disabled Particular dates & all Sundays.
return display;
}
});
});
You can use CSS to apply styles to disabled dates. Specifically targeting dates with title="Block Settlement Date"
.ui-datepicker-unselectable.ui-state-disabled[title="Block Settlement Date"] {
background:red;
}
Thank you to all, For giving precious time to help my queries.
But I found my custom solution for my problem & I would like to share here may this will help to others.
New changes added to datepicker in beforeshowday is here, in this i have added custom class.
$(document).ready(function(){
jQuery(function() {
var blockedDates = ["12/20/2022", "12/28/2022", "12/24/2022", "12/19/2022"];
var dateFormat = "yy-mm-dd";
$( "#datepicker" ).datepicker({
dateFormat:'yy-mm-dd',
minDate: 0,
daysOfWeekDisabled: [0, 6],
onSelect: function(dateStr) {
var _frmdate = $.trim($(this).val());
jQuery("#blockModalDateItem").modal("show");
jQuery("#bk_blockdt").val(_frmdate);
jQuery(".status_msg").html("");
},
beforeShowDay: function(date){
show = true;
if(date.getDay() == 0 ){show = false;}
for (var i = 0; i < blockedDates.length; i++) {
if (new Date(blockedDates[i]).toString() == date.toString()) {show = false;}
}
var display = [show,'highlight-bkdate',(show)?'':'Block Settlement Date']; //Disabled Particular dates & all Sundays.
return display;
}
});
});
In this class i have applied some css for giving highlight purpose.
.highlight-bkdate span {
color: #fff!important;
background-color: red!important;
border: 3px solid #191970!important;
}
Now this state it will highlight all disabled dates, Now I want to only particular dates & sunday should highlight.
So, I called this function after datepicker load. In this I again removed class on those dates which I do not want to highlight.
setTimeout(removeClassHigh, 50);
function removeClassHigh(){
var blockedDates = ["12/20/2022", "12/28/2022", "12/24/2022", "12/19/2022"];
var dayNames = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
var currentYear = jQuery(".ui-datepicker-year").text();
var currentMonth = jQuery(".ui-datepicker-month").text();
var oneMonth = 1;
var dat = new Date('1 ' + currentMonth +' ' +currentYear);
var monthNo = dat.getMonth();
oneMonth += Number(monthNo);
var f1 = 1;
var d = new Date();
var day = d.getDate();
$('.ui-state-default').each(function () {
var checkCurrentDt = new Date(oneMonth+'/'+f1+'/'+currentYear);
var checkThisDay = checkCurrentDt.getDay();
var checkThisDate = String(checkCurrentDt.getDate()).padStart(2, '0');
if(day==f1){
return false;
}else{
if(dayNames[checkThisDay]!="Sunday"){
if (jQuery.inArray(oneMonth+'/'+checkThisDate+'/'+currentYear, blockedDates) === -1) {
$(this).parent().removeClass('highlight-bkdate');
}
}
}
f1++;
});
}
So in this way found this solution.
And Result as below:
Thank you to all..!!
Have a great day :)
How can I show dataLabels or tooltip for outer circle of packedbubble?
For example in Carbon emissions around the world (2014) sample, i need to show a tooltip for each continent, when hovering on them. or if possible show dataLabels for each of them
Notice that the outer circle is just a path without any properties like x, y etc, so it wouldn't work with the Highcharts tooltip feature. The only solution which came to my mind is to create a custom tooltip on mouseover event on this path.
Demo: https://jsfiddle.net/BlackLabel/9gkdfsnj/
Code:
events: {
render() {
var
chart = this,
series = chart.series[0],
graphic = series.parentNode.graphic,
tooltip = document.getElementById('tooltip'),
text;
text = "Sum value: " + Math.floor(series.yData.reduce((a, b) => a + b, 0));
graphic.element.onmouseover = function() {
tooltip.style.visibility = "visible";
tooltip.innerHTML = text;
tooltip.style.left = graphic.x + (tooltip.offsetWidth /2) - chart.plotLeft + 'px';
tooltip.style.top = graphic.y + graphic.height / 2 + 'px'
}
graphic.element.onmouseout = function() {
tooltip.style.visibility = "hidden"
}
}
}
It is just a simple example, feel free to improve it.
Add value key
[{
name: 'Animals',
value: 867,
data: [{
name: 'Lion',
value: 167
}, {
name: 'Croatia',
value: 200
},
{
name: "Dog",
value: 97
}],
}]
Add below lines inside Tooltip
tooltip: {
useHTML: true,
formatter : function(){
let childtooltip = "";
if(this.point != undefined && this.point != null){
if((this.point.name != undefined && this.point.name != null) && (this.point.value != undefined && this.point.value != null)){
childtooltip = `<b>${this.point.name}:</b> ${this.point.value}`;
}
}
if(childtooltip == ""){
return `<b>${this.series.userOptions.name}:</b> ${this.series.userOptions.value}<br>`
}else{
return `${childtooltip}`;
}
}
}

I've got the code for Highcharts in combination with Thingspeak from here:
https://forum.arduino.cc/index.php?topic=213058.0
My problem is, I am not able to implement the different suffix into the code :-(. I've tried a lot, but I dont understand the mechanism behind the Java code.
I've tried some things, but result is, I only have one datafield for the first series but not for the other series...
Formatter function is on line 246.
My different yAxies on line 286.
How can formatter decide which yAxies do actual series use?
Maybe somebody have fun to help me?
http://jsfiddle.net/cbmj8rku/
Best regards, David
Each series is assigned to one yAxis. You can detect which series uses which axis for example by axis title:
tooltip: {
formatter: function() {
var points = this.points,
title,
result = '';
Highcharts.each(points, function(p) {
result += p.y;
title = p.series.yAxis.axisTitle.textStr;
if (title === 'yAxis1') {
result += 'suffix1<br>'
} else if (title === 'yAxis1') {
result += 'suffix2<br>'
} else {
result += 'suffix2<br>'
}
});
return result
}
}
Live demo: http://jsfiddle.net/BlackLabel/ncvtxoke/
I changed the code like this:
http://jsfiddle.net/cbmj8rku/20/
formatter: function() {
var d = new Date(this.x + (myOffset*60000));
var _Min = (d.getMinutes()<10) ? '0' + d.getMinutes() : d.getMinutes();
var _Sec = (d.getSeconds()<10) ? '0' + d.getSeconds() : d.getSeconds();
var s = d.getHours() + ':' + _Min + ':' + _Sec + '<br/>';
$.each(this.points, function () {
s += '<br/>' + this.series.name + ' <b>' + this.y + this.series.yAxis.userOptions.labels.suffix + '</b>';this.series.tooltipOptions.valueSuffix[this.point.index];
});
return s;
}
I'm trying to set the min zoom (max range) of my chart. Basically I'm trying to do the opposite of the minRange property. I'm struggling for a while with this problem. I have a "solution", but I don't like it, this solution allow the user to choose a range greater then the "max range", and immediately correct it.
POSSIBLE SOLUTION
$(function() {
var lastMin;
var lastMax;
var maxRange = 12 * 30 * 24 * 3600 * 1000; //12 month
$('#container').highcharts('StockChart', {
scrollbar: {
liveRedraw: false
},
xAxis: {
events: {
afterSetExtremes: function(e) {
var max = this.max,
min = this.min;
if (lastMin && lastMax) {
if(max-min > maxRange) {
if (min < lastMin) {
min = max - maxRange;
} else {
max = min + maxRange;
}
}
}
var x = this;
setTimeout(function(){
x.setExtremes(min,max); //chart xAxis
}, 1);
lastMin = min;
lastMax = max;
}
}
},
rangeSelector: {
selected: 1
},
series: [{
name: 'USD to EUR',
data: usdeur
}]
});
});
I want to block the user from choosing a range greater than the allowed, in other words, block the navigator when it's too big
I'm also following this issue, I tried all the proposed solution, but I'm having errors ("Uncaught ReferenceError: Highcharts is not defined")
Thanks Sebastian!
I managed to find a solution (fiddle) wrapping the "render" function. Doing that I managed to really set a "min zoom" on the navigator bar.
$(function() {
var lastX0;
var lastX1;
var maxRange = 100; //100 pixels
(function (H) {
H.wrap(H.Scroller.prototype, 'render', function (proceed) {
console.log(arguments)
if(arguments[4] - arguments[3] > maxRange + 2) {
if (arguments[3] < lastX0) {
arguments[3] = lastX0;
} else {
arguments[4] = lastX1;
}
}
proceed.apply(this, [].slice.call(arguments, 1));
lastX0 = arguments[3];
lastX1 = arguments[4];
});
}(Highcharts));
$('#container').highcharts('StockChart', {
scrollbar: {
liveRedraw: true
},
series: [{
name: 'USD to EUR',
data: usdeur
}]
});
var highchart = $('#container').highcharts();
var extremes = highchart.xAxis[0].getExtremes();
var rangeTotal = extremes.max - extremes.min;
var f = maxRange / $('#container').width();
highchart.xAxis[0].setExtremes(extremes.max - (f * rangeTotal), extremes.max);
});
In the sample code I'm used a fixed amount of pixels, but in my real application i'm making it dynamic. I making this, because I can't use the data grouping property in the software that I'm working, and since the minimum size of a bar in a chart is 1 pixel (obviously) highcharts hide some bars (or points).
I'm setting the minimum zoom so all bar in the displayed range are visible , since the user can't display a higher range in the x Axis the "hidden" bar "problem" (is an awesome feature, but I can't make use of it) won't happen
I build a chart like the lazy loading example (http://www.highcharts.com/stock/demo/lazy-loading) but with having the input fields of the range selector.
When I zoom in everything is fine. Now I would like to change the selected range by using the input fields.
But I am not able to change the input to values beyond the zoomed area despite the fact I have more data visible in my navigator.
In the setExtremes function I am doing some calculations:
DX.IPFixGraphModule.prototype.setExtremes = function(e) {
var fromTime,
maxZoom = 30 * 60 * 1000,
now = new Date().getTime();
if (e.min) {
fromTime = e.min;
} else {
fromTime = e.dataMin;
}
fromTime = Math.round(fromTime);
var diff = now - fromTime;
// -1 month = max 1 week zoom
if (diff >= 2592000000) {
maxZoom = 7 * 24 * 60 * 60 * 1000;
}
// -1 week = max 12 hour zoom
else if (diff >= 604800000) {
maxZoom = 12 * 60 * 60 * 1000;
}
// this refers to axis
// #see http://api.highcharts.com/highstock#Axis.update
this.update({
minRange: maxZoom
}, false);
};
But the values I receive in e.min and e.max are not the original input values but already corrected to the displayed time range.
// handle changes in the input boxes
input.onchange = function () {
var inputValue = input.value,
value = (options.inputDateParser || Date.parse)(inputValue),
xAxis = chart.xAxis[0],
dataMin = xAxis.dataMin,
dataMax = xAxis.dataMax;
// If the value isn't parsed directly to a value by the browser's Date.parse method,
// like YYYY-MM-DD in IE, try parsing it a different way
if (isNaN(value)) {
value = inputValue.split('-');
value = Date.UTC(pInt(value[0]), pInt(value[1]) - 1, pInt(value[2]));
}
if (!isNaN(value)) {
// Correct for timezone offset (#433)
if (!defaultOptions.global.useUTC) {
value = value + new Date().getTimezoneOffset() * 60 * 1000;
}
// Validate the extremes. If it goes beyound the data min or max, use the
// actual data extreme (#2438).
if (isMin) {
if (value > rangeSelector.maxInput.HCTime) {
value = UNDEFINED;
} else if (value < dataMin) {
value = dataMin;
}
} else {
if (value < rangeSelector.minInput.HCTime) {
value = UNDEFINED;
} else if (value > dataMax) {
value = dataMax;
}
}
// Set the extremes
if (value !== UNDEFINED) {
chart.xAxis[0].setExtremes(
isMin ? value : xAxis.min,
isMin ? xAxis.max : value,
UNDEFINED,
UNDEFINED,
{ trigger: 'rangeSelectorInput' }
);
}
}
};
(Code taken from highstock.src.js around line 21126)
So I cannot extend my zoom beyond the current active selection, but the navigator displays more data.
Does anyone know a way to set a date beyond the currently zoomed time range?
Possible Solution
I solved it by checking the navigator range in the "afterSetExtremes" Event.
DX.IPFixGraphModule.prototype.afterSetExtremes = function(e) {
if (e.trigger === 'rangeSelectorInput') {
var fromValue = this.stockchart.rangeSelector.minInput.value,
toValue = this.stockchart.rangeSelector.maxInput.value,
fromTime = parseDateTime(fromValue),
toTime = parseDateTime(toValue),
navigatorAxis = this.stockchart.get('navigator-x-axis'),
maxValue = navigatorAxis.dataMax,
minValue = navigatorAxis.dataMin;
if (fromTime < minValue) {
fromTime = minValue;
}
if (toTime > maxValue) {
toTime = maxValue;
}
this.stockchart.xAxis[0].setExtremes(fromTime, toTime);
} else {
var fromTime,
toTime;
if (e.min) {
fromTime = e.min;
} else {
fromTime = e.dataMin;
}
fromTime = Math.round(fromTime);
if (e.max) {
toTime = e.max;
} else {
toTime = e.dataMax;
}
toTime = Math.round(toTime);
this.settings.afterSetExtremes({startTimestamp: fromTime, endTimestamp: toTime});
}
};
Or see solution below and override the method.
There is no default API for that. Extend Highcharts via overriding drawInput function (your second code snippet).
There is a part of code that you should comment out or remove - the if clause after:
// Validate the extremes. If it goes beyound the data min or max, use the
// actual data extreme (#2438).
Example: http://jsfiddle.net/epL7awo4/1/
