With Symfony UX, in order to assure that a custom chart could be rendered, I started with the sample from documentation. The rendered page is effectively blank. In the browser's console is this string:
<canvas data-controller="symfony--ux-chartjs--chart" data-symfony--ux-chartjs--chart-view-value="{"type":"line","data":{"labels":["January","February","March","April","May","June","July"],"datasets":[{"label":"My First dataset","backgroundColor":"rgb(255, 99, 132)","borderColor":"rgb(255, 99, 132)","data":[0,10,5,2,20,30,45]}]},"options":{"scales":{"y":{"suggestedMin":0,"suggestedMax":10}}}}"></canvas>
I interpreted that string to mean that the rendering process got as far as chart.js. But what later step(s) could prevent the chart from being fully rendered? Earlier step(s)?
assets\controllers.json:
{
"controllers": {
"#symfony/ux-chartjs": {
"chart": {
"enabled": true,
"fetch": "eager"
}
}
},
"entrypoints": []
}
package.json includes:
"devDependencies": {
...
"#symfony/ux-chartjs": "file:vendor/symfony/ux-chartjs/assets",
...
"chart.js": "^3.4.1",
...
}
../node_modules/chart.js/dist/chart.js: Chart.js v3.9.1
Thankfully(?), there are no discussions of Chart.js at the Mozilla forums. Applying the principle of pressing buttons until things change, I learned that the ad blocker I use was preventing the chart from being rendered. Why That, Firefox?

I'm developing a new tab replacement extension for Google Chrome and I'd like to allow the user to customize the background, to do so I'm using the storage.sync API as suggested by this page.
The problem is that the style changes are applied asynchronously, so the default background (white) is briefly used during the page load resulting in unpleasing flashes.
Possible (unsatisfying) solutions are:
do not allow to change the background;
hard code a black background in the CSS (and move the problem to custom light backgrounds);
use a CSS transition (still super-ugly).
What could be an alternative approach?
Follows a minimal example.
manifest.json
{
"manifest_version": 2,
"name": "Dummy",
"version": "0.1.0",
"chrome_url_overrides": {
"newtab": "newtab.html"
},
"permissions": [
"storage"
]
}
newtab.html
<script src="/newtab.js"></script>
newtab.js
chrome.storage.sync.get({background: 'black'}, ({background}) => {
document.body.style.background = background;
});
I come up with a reasonable solution. Basically since the localStorage API is synchronous we can use it as a cache for storage.sync.
Something like this:
newtab.js
// use the value from cache
document.body.style.background = localStorage.getItem('background') || 'black';
// update the cache if the value changes from the outside (will be used the next time)
chrome.storage.sync.get({background: 'black'}, ({background}) => {
localStorage.setItem('background', background);
});
// this represents the user changing the option
function setBackground(background) {
// save to storage.sync
chrome.storage.sync.set({background}, () => {
// TODO handle error
// update the cache
localStorage.setItem('background', background);
});
}
This doesn't work 100% of the times but neither do the simple:
document.body.style.background = 'black';
So it's good enough.¹
¹ In the real extension I change the CSS variables directly and I obtain much better results than setting the element style.
I've never worked with Bokeh before, so apologies if this question doesn't make sense. I have a plot that someone else generated using Bokeh and it has a huge JSON object (docs_json) that is all on the same line. I need to import this plot into a WordPress site which has a line length limit. Is there any way I can get Bokeh to generate that JSON in a prettified form rather than squishing the whole thing onto one line?
I'm in a situation where I'm working with 100s of plots being generated continuously, so I'd prefer not to have to manually touch each plot after it is generated.
Yes, the simplest way is to use the BOKEH_PRETTY environment variable when running any Bokeh code, e.g.
BOKEH_PRETTY=true python iris.py
Results in HTML output with embedded JSON that looks like:
<script type="application/json" id="4074acb8-0b70-4591-8d43-99873a9e1bc4">
{
"9d745210-1f6a-4c22-b8ca-c3d2b3829a8f": {
"roots": {
"references": [
{
"attributes": {
"bottom_units": "screen",
"fill_alpha": {
"value": 0.5
},
...
],
"root_ids": [
"ce2c1a38-e3e5-4155-9a80-6860dc284dbc"
]
},
"title": "Bokeh Application",
"version": "0.12.15dev1"
}
}
</script>
All of Bokeh's settings and their associated environment variables are documented in the reference guide:

I am using related Shield UI ASP.NET Charts on a web page. What I need is to be able to provide the user the option to choose whether to show the dataPointText or not. For that purpose I have put a checkbox below the second grid and am trying to use the following code:
detailChartElement.shieldChart($.extend(initialOptions, {
primaryHeader: {
text: headerText
},
if (document.getElementById("CheckBox1").checked == true){
seriesSettings: {
line: {
dataPointText: {
enabled: true,
borderColor: 'red',
borderWidth:3
}
}
},
},
but when I put the code and none of the grids on the page shows. I checked quite carefully the code but don’t see any missed out commas or anything that should prevent it from working.
The mistake you are making is not syntactical but conceptual. Within the code that creates the chart:
detailChartElement.shieldChart($.extend(initialOptions, {
}));
you may place nothing but the properties of the Shield UI ASP.NET chart and their properties. You may not have any logical checks like IF(). However you may have additional variables and their values.
With this in mind you could use the following workaround:
In the function you use to recreate the chart you place the following code:
var showlabels = document.getElementById("CheckBox1").checked;
Than, you put the series settings code in the chart creation routine:
seriesSettings: {
line: {
dataPointText: {
enabled: showlabels,
borderColor: 'red',
borderWidth:bordersize
}
}
},
The properties and values will be always there, however they will be enabled only when the checkbox is checked.
My name is Josh and I work for a community college newspaper. I've just recently found Highcharts and have been attempting to embed a interactive graph into a post for our website, rather unsuccessfully. Actually, it's been a complete failure.
I have already read over and attempted this post to no avail:
highcharts and wordpress
There's no one I know who I can take this problem to and even though I feel like I've tried every suggested solution, Unfortunately, I'm rather illiterate when it comes to html and code. Any help would be GREATLY appreciated.
I am working with Wordpress 3.5.1 Here is the point I am currently at:
I am running: Allow PHP in Posts and Pages Plugin & Interactive Javascript and CSS.
For the header option of the post I have:
<script type="text/javascript" src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"> </script>
<script src="http://www.domain.com/wp-content/uploads/2013/03/highcharts1.js" type="text/javascript"></script>
In some of the websites (this one included), I've seen mention of uploading the Highcharts library onto your wordpress server. I've uploaded the highcharts.js file through the media library but I have a feeling that I am doing this incorrectly?
In the post itself I have placed:
[php]
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'State Funding of DSPS Services',
x: -20 //center
},
subtitle: {
text: 'Source:MPR Associates Report',
x: -20
},
xAxis: {
categories: ['2003-04', '2004-05', '2005-06', '2006-07', '2007-08',
'2008-09', '2009-10', '2010-11', '2011-2012', '2012-13']
},
yAxis: {
title: {
text: '$ Million'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
this.x +': '+ this.y +' Million';
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: [{
name: 'College Total Funding',
data: [77.8, 81.8, 86.2, 102.1, 109.3, 108.9, 64.9, 64.8, 64.6, 65.7]
}]
});
});
});
[/php]
<div id="container" style="width: 100%; height: 400px"></div>
The page comes up blank, as it has been for the past hundred attempts or so. I apologize if this is post in the wrong spot or undesired. Any advice or solutions are greatly appreciated.
Thank you,

In order to get a chart rendered, you need several things to be in place:
Include the highcharts.js - done
Include some javascript which defines and creates a chart - done
Give highcharts a place to put the chart - ?
I think you may be missing the last element. This is done by including a tag inside your post somewhere. The div can be named using the 'id' property as follows:
<div id='container'>mydiv</div>
You have already told highcharts that you want to 'renderTo' a place called 'container', so this should be all you need.
To add this in wordpress, go into the post editor and make sure you are in 'html' mode. In my version of wordpress, this is a tab just to the top right of the post editing pane with the options 'visual' and 'html'.
In html mode, just add my div code in the place where you want the chart to appear. Hopefully that will do the trick.
there could be several reasons for the chart not showing up.
1)The scripts (jquery and highcharts) need to be loaded onto your page and this is not immediately obvious in wordpress. There's a couple of ways - if you aren't a coder then the simplest is to go to the header.php of your theme. (Appearance->Editor) and look for the header.php file on the right hand side. In the head section you'll need to register the highcharts library...
wp_register_script('myHighchartsHandle','highcharts/js/highstock.js',array('jquery'),'1.0a');
wp_enqueue_script('myHighchartsHandle');
The path to the high stock/highcharts library will change depending on where it is on your server of course.
2) The code is javascript - your supplied code has php tags. I think you could edit that to have js tags in the square brackets and install the 'Allow javascript in posts and pages' plugin. Note that plugin needs you to prefix any square brackets in code with a backslash so you'll need to do that to get the data series formatted properly.
3) It does look like you have a div container outside of your code which is good. But as the other answer suggest you will need that and the id has to match the renderTo in the code.
4) If it doesn't work after these 3 steps then you could be falling foul of jQuery noConflict.Wordpress sets jquery in this mode by default.
Instead of $ in your js code you may have to replace with jQuery. The highcharts library is ok in the code you've used.
Happy to help more if required. I have since built much of this into a plugin which is much cleaner...
i want to make a chrome extension on google reader and i found a problem. content script can not access to iframes. For all n, window.frames[n] = undefined. And i have this "all_frames": true in manifest.json. Or someone could tell me how to add a button under each article. Thank you!
From taking a quick look at Google Reader's rendered HTML, the only button that is in an IFRAME appears to be the Google Plus +1 button - all the other buttons are not in an IFRAME. So you don't need to worry about the IFRAME.
I'm assuming that the existing buttons are the buttons that appear underneath each article: +1, Share, Email, Keep Unread, Add Tags.
If you want to add a new button to the existing article buttons all you need to do is enumerate the DOM - specifically the "entry-actions" DIV classes and append say a new SPAN with your element/button to each article.
I suspect (but not sure) that Reader may dynamically update the DOM with new articles. If this is the case you may need to track new articles being added to the DOM so you can add your button again. To do this add an event listener for DOMNodeInserted - e.g.
document.addEventListener('DOMNodeInserted', onNodeInserted, false);
UPDATE:
The reason you can't see ".entry-actions" class is because it is added dynamically.
Here is a working very basic example. This will monitor the DOM and when it sees an entry-actions DIV that doesn't have our ".myclass" SPAN button, will add it.
You need to have jquery included in your extension for this to work. I've used jquery-1.7.1.min.js in this example. You will also need an icon file called foo.png too if you cut and paste the example.
manifest.json
{
// Required
"name": "Foo Extension",
"version": "0.0.1",
// Recommended
"description": "A plain text description",
"icons": { "48": "foo.png" },
//"default_locale": "en",
// Pick one (or none)
"browser_action": {
"default_icon": "Foo.png", // optional
"default_title": "Foo Extension" // optional; shown in tooltip
},
"permissions": [ "http://*/", "https://*/", "tabs" ],
"content_scripts": [
{
"matches": ["http://*/*", "https://*/*"],
"js": ["jquery-1.7.1.min.js", "content_script.js" ],
"run_at": "document_idle"
}
]
}
content_script.js
var timer;
document.addEventListener('DOMNodeInserted', onNodeInserted, false);
function onNodeInserted(e)
{
if(timer) clearTimeout(timer);
timer = setTimeout("addButtons()", 250);
}
function addButtons()
{
console.log('add buttons');
var $actions = $(".entry-actions").filter(function() {
return $(this).find('.myclass').length === 0;
});
$actions.append('<span class="myclass">My button</span>');
}
