2 markers at the same position how not display the tooltip of the hidden marker? When I pass over the visible markers.
map.on('pointermove', function(e) {
var feature = map.forEachFeatureAtPixel(e.pixel, function(feature, layer) {
if (layer == layer_1) {
return feature;
}
});
map.getTarget().style.cursor = feature ? 'pointer' : '';
tooltip.style.display = feature ? '' : 'none';
if (feature){
overlay.setPosition(e.coordinate);
tooltip.innerHTML = 'marker hidden';
}
});
Can't just comment or I would since I only want to ask you: did you try using setStyle() instead to change the style? That usually forces the change event. I'm asking that because I had a similar issue here to hide/show features.

I am trying to hide specific legend items on my graph (http://api.highcharts.com/highcharts/legend). If I loop through the chart.legend.allItems and try to change a specific items visible property it does not effect the legend at all.
$.each(chart.legend.allItems, function() {
this.visible = false;
});
How can I hide a specific legend item on my graph ?
I think this is being made out to be more complex than it needs to be.
You can set showInLegend to false in your config options for the series.
If you need to do it programmatically, you can use series.update() to accomplish it dynamically.
Reference:
http://api.highcharts.com/highcharts/plotOptions.series.showInLegend
http://api.highcharts.com/highcharts/Series.update
I found other solution in this question
var item = chart.series[1];
//hide serie in the graph
item.hide();
item.options.showInLegend = false;
item.legendItem = null;
chart.legend.destroyItem(item);
chart.legend.render();
EDIT:
Other solution for last version of highcharts:
$('#container').highcharts().series[1].update({ showInLegend: false });
You can do that with the load event - Highcharts Doc
chart: {
events: {
load: function() {
var myChart = this;
$.each(myChart.series, function(index, serie) {
if(index === 2 ) { // hide serie
serie.hide();
}
});
}
}
},
Here a fiddle
if you want to hide some labels you can add some css class to hide them according to some special feature of the series. I pass an example in which the series is hidden with empty data and also hide the label:
for (var i = 0; i < chart.series.length; i++) {
if (chart.series[i].dataMax === 0) {
chart.series[i].hide();
}
}
$("#charContent").find('.highcharts-legend-item-hidden').each(function () {
$(this).addClass('hidden');
});
In the css:
.highcharts-legend-item-hidden.hidden {
display: none;
}
Maybe it's not a very clean solution but it works for me
Working on an OL3 map, and am getting stuck on popover style. I haven't added any CSS to change it at all and it is currently being handled by default Bootstrap settings.
Okay so the problem: each word is being displayed on it's own line. How can I change this? Or, a better question, how do I control the style of the popovers?
This is was it looks like now: http://i.imgur.com/lrLYbag.png
The code handling popups:
//popups
var element = document.getElementById('popup');
var popup = new ol.Overlay({
element: element,
positioning: 'bottom-center',
stopEvent: false
});
map.addOverlay(popup);
// display popup on hover
map.on('pointermove', function(evt) {
var feature = map.forEachFeatureAtPixel(evt.pixel,
function(feature, layer) {
return feature;
});
if (feature) {
var geometry = feature.getGeometry();
var coord = geometry.getCoordinates();
popup.setPosition(coord);
$(element).popover({
'placement': 'top',
'html': true,
'content': feature.get('name')
});
$(element).popover('show');
} else {
$(element).popover('destroy');
}
});
Thanks!
I think you just need to add some css to the #popup element you're using for the popup.
Something like:
#popup {
min-width: 280px;
}
Take a look at this example http://openlayers.org/en/master/examples/popup.html for styling ideas.
I have a pie chart and need to slice out some point (for examle, second slice in jsfiddle example) by clicking a buttom. How can I do it?
I've tried some updating, but it doesn't work
$('#button').click(function() {
var Chart2 = $('container').highcharts();
Chart2.options.series[0].data[1].sliced = true;
Chart2.options.series[0].data[1].selected = true;
Chart2.redraw();
})
jsfiddle example
The method you need is 'select' on the point object. This is on series, but not in options as you tried:
$('#button').click(function() {
chart.series[0].data[1].select();
})
e.g.
http://jsfiddle.net/JWFm5/
You can also use slice() function.
http://jsfiddle.net/wu3jY/2/
$('#button').click(function() {
chart.series[0].data[0].slice();
});
I have like 50 different series, so by default, I have them hidden, so the user simply clicks on the ones he wants to see.
Sometimes, one wants to show all, or hide all, quickly. I cannot figure out how to toggle all on/off. Is this possible at all? I assume so, but cannot figure out a way to do it.
Hide each series using series.setVisible(false, false), reference. - After all series will be hidden call chart.redraw() to redraw chart only once.
this solution is based on http://jsfiddle.net/pGuEv/
var chart = $('#chart-container').highcharts();
var $hide_show_all_button = $('#hide_show_all_series_button');
$hide_show_all_button.click(function() {
var series = chart.series[0];
if (series.visible) {
$(chart.series).each(function(){
this.setVisible(false, false);
});
chart.redraw();
$hide_show_all_button.html('show all');
} else {
$(chart.series).each(function(){
this.setVisible(true, false);
});
chart.redraw();
$hide_show_all_button.html('hide all');
}
});
I'm working with Highchart.
I've got a multiple series graph in which each series have their own y-axis.
pretty much like this one (jsfiddle)
when we click on the legend item for a series, it hides it and the associated y-axis
(using showEmpty:false helped hiding also the name of the axes)
What I'm trying to achieve is hiding the y-Axis of a given series without hiding the series itself.
I tried to hide it by modifying the showAxis property like this :
serie.yAxis.showAxis = false;
but it doesn't work.
Anyone knows how I should do ?
EDIT : I managed to edit the text so I can remove the axis title by setting the text to null but its not enough to hide the whole axis and its values.
here's what i did to edit the text:
serie.yAxis.axisTitle.attr({
text: null
});
Highcharts 4.1.9+
Since 4.1.9, there is an option Axis.visible which can be used to show/hide an axis, demo: http://jsfiddle.net/3sembmfo/36/
Older versions of Highcharts
It's a new feature for Highcharts 3.0 - that allows to update axes in realtime: chart.yAxis[0].update(object) - as object takes the same options as for creating chart. For example:
chart.yAxis[0].update({
labels: {
enabled: false
},
title: {
text: null
}
});
And jsFiddle: http://jsfiddle.net/39xBU/2/
EDIT:
Use below snippet to hide/show axis by just calling axis.hide() and axis.show(). Live demo: http://jsfiddle.net/39xBU/183/
(function (HC) {
var UNDEFINED;
HC.wrap(HC.Axis.prototype, 'render', function (p) {
if (typeof this.visible === 'undefined') {
this.visible = true;
}
if(this.visible) {
this.min = this.prevMin || this.min;
this.max = this.prevMax || this.max;
} else {
this.prevMin = this.min;
this.prevMax = this.max;
this.min = UNDEFINED;
this.max = UNDEFINED;
}
this.hasData = this.visible;
p.call(this);
});
HC.Axis.prototype.hide = function () {
this.visible = false;
this.render();
HC.each(this.plotLinesAndBands, function (plotLine) {
plotLine.render();
});
};
HC.Axis.prototype.show = function () {
this.visible = true;
this.render();
HC.each(this.plotLinesAndBands, function (plotLine) {
plotLine.render();
});
};
})(Highcharts);
It's actually gotten simpler. You only have to set the yAxis title attribute to false:
yAxis: {
title: false
},
Here is an example: jsfiddle example
We can hide Yaxis label without hiding the y-Axis without hiding the series by returning the empty string as follows:
yAxis: {
title: '',
labels: {
formatter: function() {
return '';
},
style: {
color: '#4572A7'
}
}
},
For newer versions (I'm using the 6.2.0), the yAxis property has a parameter called gridLineWidth. Just set it to 0 and the grids for that axis are going to disappear. In this JSFiddle there is an example of it.
However, if you are in styled mode this it's trickier. Here, you have to set a className for the target axis and then set the CSS like this:
.highcharts-yaxis-grid {
&.right-axis {
path {
stroke: none;
}
}
}
For example, this will make dissapear the grids of the axis with a className set as right-axis. This allow to have different styles for the multiple axis.
