I want to get minortickmark value when i click on minortickmark in axis of barchart. I am getting all tickmark positions using getMinorTickPositions() in barchart. I have searched all js code in highcharts i am unable to find it.can anyone please help me. here is my code.
$('.highcharts-axis').hover(function(event) {
alert(this.x);
getAxisValue();
return false;
});
function getAxisValue(){
var chart = $('#container').highcharts();
var data= chart.xAxis[0].getMinorTickPositions();
//alert(chart.value());
alert(data);
};
In general to add click event to minor ticks will require some JS and Highcharts skills. I will try to guide you a little:
chart.xAxis[0].minorTicks - this is where all minor ticks are stored
to add click event to minorTick, use: chart.xAxis[0].minorTicks['value'].mark.on('click', callback)
now in callback you can do your stuff for specific minor tick

Consider the following toy example: jsfiddle
chart: {
events: {
render: myfunc
}
},
...
function myfunc() {
var chart = this;
chart.series.forEach(function(s) {
s.setState('inactive', true);
});
chart.series[0].setState('hover');
}
The intended behavior is to set the state of the first series as hover while setting all other series as inactive after load and redraw events.
The code works as intended after load
However, it doesn't work after redraw (via the select box). After selecting an option in the box, the series are rendered as normal instead of as inactive UNLESS any series had been previously hovered. That is, the code works if you interact with any series AND THEN select an option in the box, but it doesn't work if you select an option in the box immediately after the loading without interacting on the series.
Surprisingly, after some inspection in the console, I noted that in any case the intended states are properly passed to the series object. So, why the states are not properly rendered?
*NOTE: In my actual application the hovered series is not necessarily the first one, but it varies depending on the output of other function. I'm aware that "myfunc" could be simplified in the current example, but for general purposes please suggest an answer keeping the basic structure if possible.
This seems to be related to this issue from HighChart's GitHub. In your case, HighCharts is correctly updating the series' state. However, while rendering it fails to set the proper opacity value associated with the 'inactive' state. The workaround is to explicitly set the opacity of the series to the same value it should have in the 'inactive' state.
// F U N C T I O N S E T S T A T E
function myfunc() {
var chart = this;
chart.series.forEach(function(s) {
//explicit opacity
s.opacity = 0.2;
s.setState('inactive', true);
});
chart.series[0].setState('hover');
}
Thank you for sharing this issue, it seems that it is a regression after the last release.
In the previous version it used to work fine: https://jsfiddle.net/BlackLabel/Lbpvdwam/
<script src="https://code.highcharts.com/8.1.0/highcharts.js"></script>
<script src="https://code.highcharts.com/8.1.0/highcharts-more.js"></script>
I reported it on Highcharts Github issue channel where you can follow this thread: https://github.com/highcharts/highcharts/issues/13719
If you don't need any new features/bugfixes use the previous version as a temporary workaround.
I am trying to show the loading animation during a function call that takes some time. The function call is searching a large array that is already loaded. After the search, matching items are inserted into a table. The table is cleared prior to starting the search.
The problem is the animation only displays during the brief moment when the page updates.
Here is my code:
var interval = setInterval(function ()
{
$.mobile.loading('show');
clearInterval(interval);
}, 1);
DoSearch(term, function ()
{
var interval = setInterval(function ()
{
$.mobile.loading('hide');
clearInterval(interval);
}, 1000);
});
//The search function looks like this (detail omitted for brevity):
function DoSearch(term)
{
$("table#tableICD tbody").html('');
// also tried:
/*$("table#tableICD tbody")
.html('')
.table()
.closest("table#tableICD")
.table("refresh")
.trigger("create");*/
var tr = '';
$.each(codes, function (key, value)
{
// determine which items match and add them as table rows to 'tr'
});
$("table#tableICD tbody")
.append(tr)
.closest("table#tableICD")
.table("refresh")
.trigger("create");
callback();
}
The search works properly and adds the rows to the table. I have two unexpected behaviors:
The table does not clear until the search is complete. I have tried adding .table("refresh").trigger("create") to the line where I set the tbody html to an empty string. This does not help. (see commented line in the code)
As I mentioned, the animation displays briefly while the screen is refreshing. (Notice I set the interval to 1000 in the second setInterval function just so I could even see it.)
The suggestions I have read so far are to use setInterval instead of straight calling $.mobile.loading, which I have done and placing the search in a function and using a callback, which I have also done.
Any ideas?
Let me give you a few suggestions; they will probably not solve all your issues but they may help you found a solution.
jQuery Mobile is buggy, and for some features, we will never know were they intended to work like that or are they just plain bugs
You can call $.mobile.loading('show') on its own only in pageshow jQuery Mobile event. In any other case, you need to do it in interval or timeout.
It is better to do it in timeout, mostly because you are using less code. Here an example I made several years ago: http://jsfiddle.net/Gajotres/Zr7Gf/
$(document).on('pagebeforecreate', '[data-role="page"]', function(){
setTimeout(function(){
$.mobile.loading('show');
},1);
});
$(document).on('pageshow', '[data-role="page"]', function(){
// You do not need timeout for pageshow. I'm using it so you can see loader is actualy working
setTimeout(function(){
$.mobile.loading('hide');
},300);
});
It's difficult to enhance any jQuery Markup in real time after a page was loaded. So my advice is to first generate new table content, then clean it, and then update markup using .table("refresh").
Do table refresh only once, never do it several times in the row. It is very resourced heavy method and it will last a very long time if you run it for every row
If you are searching on keypress in the input box then showing it in the table; that is the least efficient method in jQuery Mobile. jQM is that slow, it is much better to use listview component which is least resource extensive.
I'm using react-highcharts and I'm trying to find a way to trigger an event when one of the Y-axis categories is being clicked. I'm using xrange graph.I want to get the offset of the value that was clicked. For example, if i have:
CatA
Catb
CatC
If I will click on CatB I will get 1.
I found a jquery solution, which give me the value itself. Its not a problem to get all the elements and iterate over them and found the offset myself. The solution of jquery:
$("#container .highcharts-yaxis-labels text").click(function() {
alert($(this).text());
});
I'm looking for react/react-highcarts solution for that.
Update
Thanks Kamil Kulig! Im getting trouble with the library. I import the library as
import HighchartsCustomEvents from 'highcharts-custom-events';
And nothing happned, also i added this code at componentWillMount function:
template.yAxis.events.click = function () {
alert(1);
};
I saw the docs and I didnt find any offset function, which means that sould I use jquery anyway? or do u have any idea?
Highcharts offers the custom events module that is able to handle the actions that you require.
Module reference on npm: https://www.npmjs.com/package/highcharts-custom-events
Module reference on Highcharts website: https://www.highcharts.com/products/plugin-registry/single/15/Custom-Events
Sample code:
yAxis: {
labels: {
events: {
click: function () {
// do something
}
}
}
}
I have an issue discussed here: Page after canceling print doesn't resize chart.
https://github.com/highslide-software/highcharts.com/issues/1093
I am hoping to reproduce a solution mentioned there. Basically, the solution is to set global options in Highcharts as follows:
Highcharts.setOptions({
chart: {
events: {
afterPrint: function () {
alert('called');
Highcharts.charts.forEach(function (chart) {
if (chart !== undefined) {
chart.reflow();
}
});
}
}
}
});
In my case, the page works as below:
Load the page
Start an Ajax call to retrieve data and draw four charts.
I tried to use the above solution either at page load or after the ajax call. However, afterPrint was never called. Note that I put "alert('called')" there to prove it.
What is the right way to add global afterPrint?
Regards.
I got it working now. I was using version 4.0.4, with which afterPrint did not work as expected. Now I am using the latest version 4.1.9 and afterPrint works as expected without any code change on my side.
I call the global setup at the page load.
Hope this helps.
I did it in easier way by adding following in my script
Highcharts.setOptions({
chart: {
events: {
afterPrint: function () {
jQuery(window).resize()
}
}
}
});
I have been trying to implement the autocomplete and have come across a problem that has stumped me. The first time I call .autocomplete it all works fine and I have no problems. If, however, I call it after I have removed some (unrelated) elements from the DOM and added a new section to the DOM then autocomplete does nothing and reports no errors.
Code:-
$.ajax({
type : 'get',
dataType : 'json',
url : '/finance/occupations',
cache:true,
success:function(data){
occupationList = data;
$('.js-occupation').autocomplete({
source: occupationList,
messages: {
noResults: '',
results: function(){}
},
minLength : 2,
select:function(event, ui){
$('.js-occupationId').val(ui.item.id);
}
});
}
});
The background to this page is that it contains multiple sections that are manipulated as the user moves through them. Hide and show works fine and does not impact on the autocomplete. However, if I do the following:-
var section = $('.js-addressForm:last').clone();
clearForm(section);
$('div.addressDetails').append(section);
$('.js-addressForm:first').remove();
Which gives the user the bility to add multiple addresses on the previous section then the autocomplete stops working.
Any suggestions or pointers on something obvious I am missing?
I have tried to put the initialisation of the autocomplete on an event when the element gets focus and it still does not work.
You have to create the autocomplete after all other underlying objects. If you F12, you will see that the list is "visible", however it is below and hidden by all instances created after it.
If you created a div with inputs (one input being the autocomplete), then you create the automplete then the dialog instances, the autocomplete will never show. If you create the dialog then the autocomplete, no problem. The problem is the z-order
I have faced the same issue. For now to fix this, i'm creating widget on the input once input is in focus. It will help you solve the issue.
You can look for the help on
making sure some event bing only when needed
Sample code will look like this
$( "#target" ).focus(function() {
//I don't care if you manipulated the DOM or not. I'll be cautious. ;)
(function() {
$( "#combobox" ).combobox();
$( "#toggle" ).click(function() {
$( "#combobox" ).toggle();
});
})();
// use a flag variable if you want
});
This solved my problem. Hope its the solution you were looking f
