how to remove the dots from p:lineChart and draw the chart as just the continuous line?
Thanks
For others with similar problem, I did:
<p:chart type="line" model="#{myController.model}"/>
and:
LineChartSeries serie = new LineChartSeries();
serie.setShowMarker(false);
and worked fine. I'm using PrimeFaces 5.1.
There is a showMarkers attribute that isn't working for me (I'm using PrimeFaces 3.4.2) but I found a way to hide them.
It's a bit hacky, I made it working on the showcase, you just need to replace widget_category by the widget of your chart. You can even test it online from the showcase using a javascript console if your web browser allows it (tested under chromium) :
// loop through the series
for (var i = 0; i < widget_category.cfg.series.length; ++i) {
// Hide markers
widget_category.cfg.series[i].showMarker = false;
// I'm not sure you want this when talking about 'continuous line'
// but you can make your chart smooth this way :
widget_category.cfg.series[i].rendererOptions = { smooth: true };
}
// Ask a refresh using the modified configuration object
widget_category.refresh(widget_category.cfg);

Problem:
I have an array of nodes that I would like to highlight when an action happens.
My Attempted Solution
I have tried using code from the model browser, but it seems to only accept one dbId at a time. I have tried to iterate over my array and call it, but the highlighting doesn't work when that is done.
for (var i = 0; i < dbIdsArray.length; i++) {
viewerApp.getCurrentViewer().impl.rolloverObjectNode(dbIdsArray[i]);
}
Any advice on how to implement this correctly would be a great help.
Thanks
If you want to highlight a couple of dbids, there are some different ways depending on your requirement.
Maybe you can use the API Viewer3D.isolate() to highlight the
selected objects by isolating them, you can just input dbId array as
follow, also, you can zoom the selected items to the viewer window
use the API Viewer3D.fitToView() to focus on them:
viewer.isolate(dbIdArray);
viewer.fitToView(dbIdArray);
If you want to highlight the selected objects with different color,
maybe you can try the new API Viewer3D.setThemingColor(), here is the
simple code sample. Remember you need to clear the color using
Viewer3D.clearThemingColors(). The simple code sample should be like:
I'm able to highlight components using following code:
viewer.addEventListener(
Autodesk.Viewing.SELECTION_CHANGED_EVENT,
function (e) {
if(e.dbIdArray.length) {
var dbId = e.dbIdArray[0];
viewer.impl.highlightObjectNode(
viewer.model, dbId, true, false)
viewer.select([])
viewer.impl.sceneUpdated(true)
}
})
This is using function:
viewer.impl.highlightObjectNode = function(model, dbId, value, simpleHighlight)
Okay, so I need to change images on hover in my Angular app. However, due to some peculiarities of the site, it wasn't really feasible to change images on hover via css [without a ton of extra work], which would have been the best way, I realize.
So instead, I'm using ng-mouseenter and ng-mouseleave to change the images on hover.
landing.jade
img.share-button(src='images/btn_share.png', ng-click='dropdownShareIcons()')
img.share-icon-top(src='{{ shareIcons[0].orig }}', data-id='0', ng-mouseenter='colorizeIcons($event)', ng-mouseleave='decolorizeIcons($event)')
img.share-icon-top(src='{{ shareIcons[1].orig }}', data-id='1', ng-mouseenter='colorizeIcons($event)', ng-mouseleave='decolorizeIcons($event)')
img.share-icon-top(src='{{ shareIcons[2].orig }}', data-id='2', ng-mouseenter='colorizeIcons($event)', ng-mouseleave='decolorizeIcons($event)')
Then in the controller I have an object which contains the paths to the images, and the functions which switch images on hover.
landing.js
$scope.shareIcons = [
{orig: 'images/follow_weibo_grey.png', hover: 'images/follow_weibo_colored.png'},
{orig: 'images/follow_wechat_grey.png', hover: 'images/follow_wechat_colored.png'},
{orig: 'images/follow_youku_grey.png', hover: 'images/follow_youku_colored.png'},
]
$scope.colorizeIcons = function($event) {
$event.target.src = $scope.shareIcons[$event.target.dataset.id].hover;
}
$scope.decolorizeIcons = function($event) {
$event.target.src = $scope.shareIcons[$event.target.dataset.id].orig;
}
This all works fine and well on my local environment, but on the production server it is veeeerrrrry slow. Like, 2-3 seconds to switch the images.
So my question is - is there an easy way to fix this? Either something within angular or a workaround/hack. Doesnt really matter as long as image switch time is sped up a bit. Or is it going to continue to be slow as long as I'm switching images via JS like this? Ideally, I would like avoid rewriting this using CSS.
Thanks in advance.
Hey bro I had the same problem, and all I could think of doing was preloading the images. That helped alot. Add a small piece of js code which loads asynchronously at the beginning of your document. Like this for example:
var images = new Array()
function preload() {
for (i = 0; i < preload.arguments.length; i++) {
images[i] = new Image()
images[i].src = preload.arguments[i]
}
}
preload(
// for (i = 0; i < $scope.members.length; i ++){
// return members[i].source + ",";
// }

I would consider optimizing the PNG image sizes. There are batch optimization tools available online, here is a blog post comparing a few of them to get you started: http://www.sitepoint.com/image-compression-tools/ perhaps you can test optimize a couple of images to see if you notice a change?

I would like to show primefaces barchart with different colors for each bar. the most close I got is like the image:
I would like to have different color those bars, like green for "on time", yellow for "warning " and red for "overdue"
I tried to used model.setSeriesColors("58BA27,FFCC33,F74A4A,F52F2F,A30303");
but if i do that each bar should be a new series, therefore I won't be able to show the labels as I wish (like the image), I got this..
last, how can I make it show 0,1,2,3 (integers) instead repeating 0_0_0_1_1_1_2_2_2 like the image 1 :/
thanks
I solved the problem by my own reading this jplot documentation, I'm posting here hope it can help someone...
for somehow, adding extender in the tag is not working for me, I have to put it via java code:
barModel.setSeriesColors("58BA27,FFCC33,F74A4A,F52F2F,A30303");
barModel.setExtender("chartExtender");
then javascript inside
<h:outputScript>
function chartExtender() {
// this = chart widget instance
// this.cfg = options
this.cfg.seriesDefaults.rendererOptions.varyBarColor = true;
}
</h:outputScript>
and done!
I'm new here, so I unfortunately cannot add a comment to your answer.
It worked for me too.
Some clarifications for other readers:
Be sure to put the <h:outputScript> under your <p:chart... like:
<p:chart type="bar" model="#{bean.someModel}">
<h:outputScript>
function chartExtender() {
// this = chart widget instance
// this.cfg = options
this.cfg.seriesDefaults.rendererOptions.varyBarColor = true;
}
</h:outputScript>
</p:chart>
The "extender" -Tag has been removed in Primefaces 5:

I'm using Mootools (don't think it is related to the problem) to drag and drop and element.
var draggable = new Drag(timeHandle, {
onDrag: function () {
var calculatedTime = calcTime();
$('timeLabel').innerHTML = calculatedTime;
},
});
Basically, I can drag my 'timeHandle' and the 'timeLabel' is getting updated properly.
The problem is that sometimes, after moving the handle a little bit, suddently, the UI is not getting updated. The 'timeHandle' is not moving and the 'timeLabel' is not getting updted.
The problem is not with the drag event, I can see it keeps on getting called.
When I move
$('timeLabel').innerHTML = calculatedTime;
everything works fine.
So, the problem is not with the 'Drag' object since the event is kept on calling.
Looks like some UI performance issue.
Thanks
To simplify your code, you can use Element.set('text', 'my text here');
var element = $('timeLabel');
var draggable = new Drag(timeHandle, {
onDrag: function () {
element.set('text', calcTime());
}
});
Also, remember to remove that last comma or it will throw errors in Internet Explorer.
OK, found a to make it work.
I still not sure what caused the problem but it looks like the 'innerHTML' command has either really poor performance which causes problems in the GUI updates or maybe some kind of internal mechanism (IE only? which is supposed to prevent the UI from updates overflow.
Anyway, instead of using the innerHTML, I'm doing the following:
var draggable = new Drag(timeHandle, {
onDrag: function () {
var calculatedTime = calcTime();
var element = $('timeLabel');
element.removeChild(element.firstChild);l
element.appendChild(element.ownerDocument.createTextNode(calculatedTime));
},
});
Works like a charm
Anyone knows how to get the variant tabs to work as actual tabs and not as a drop down?
This is how sr.wikipedia.org has it:
and this is how I have it on my zablude.com/wiki/ page:
and I've tried everything I found and searched everywhere I could think of but I wasn't able to find a solution... anyone has any ideas how this works?
They hack it in JavaScript — see this piece of code at the bottom of Медијавики:Vector.js:
//to be able to switch the language variant (overrides the default buttons with more visible ones)
function tabWorkaround() {
if(mw.config.get('wgUserVariant') == 'sr') {
var tab_urls = {};
tab_urls[0] = document.getElementById('ca-varlang-0').getElementsByTagName('a')[0].href; //Ћирилица
tab_urls[1] = document.getElementById('ca-varlang-1').getElementsByTagName('a')[0].href; //Latinica
$('#p-variants').remove();
mw.util.addPortletLink('p-namespaces', tab_urls[0], 'Ћирилица');
mw.util.addPortletLink('p-namespaces', tab_urls[1], 'Latinica');
}
}
$(document).ready(tabWorkaround);
It would probably be cleaner to do it with a MediaWiki hook, though. The following code is untested, but should work if I haven't made any silly mistakes:
// show language variants as tabs in Vector skin
function tabWorkaround( &$skintemplate, &$links ) {
$links['namespaces'] += $links['variants'];
$links['variants'] = array();
return true;
}
$wgHooks['SkinTemplateNavigation::Universal'][] = 'tabWorkaround';
(In MW 1.17, this hook is only called from the Vector skin. In MW 1.18, it will affect all skins. If you don't want that, you could test whether $skintemplate->skinname == 'vector'.)
Try $wgVectorFeatures['collapsibletabs']['global'] = false;. That is intended for the dropdown on the other side, but might work for other dropdowns as well.
