I am trying to embed a Power BI report in my web page using an iframe, but it shows page name and side right filter with the report in the web page, can we hide both page name and filter from the report?
You can configure the settings for the report. Set the below flags to false in order to achieve what you want in the settings.
settings: {
filterPaneEnabled: false,
navContentPaneEnabled: false
}
You can read about it here:
https://github.com/Microsoft/PowerBI-JavaScript/wiki/Embed-Configuration-Details
As mentioned by the other answer, you can try passing in these arguments if you are using the PowerBI JavaScript API: https://github.com/microsoft/PowerBI-JavaScript
settings: {
filterPaneEnabled: false,
navContentPaneEnabled: false
}
Docs:
https://github.com/Microsoft/PowerBI-JavaScript/wiki/Embed-Configuration-Details
Failing that, you can try to manipulate the DOM of the iframe you're using like so:
<!DOCTYPE html>
<html>
<body>
<iframe id="myframe" src="demo_iframe.htm"></iframe>
<p>Click the button to change the background color of the document contained in the iframe.</p>
<p id="demo"></p>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction() {
var x = document.getElementById("myframe");
var y = (x.contentWindow || x.contentDocument);
if (y.document) y = y.document;
y.body.style.backgroundColor = "red";
}
</script>
</body>
</html>
You can see a demo if it here:

and an explanation on how this works here:

I am using GV-API to publish a piechart with information on my website. De items published are not clickable by default, but I thought I found a way in their documentation (https://developers.google.com/chart/interactive/docs/reference#numberformatter)
Implementation as follows:
<div id="chart_{!! $id !!}"></div>
<script type="text/javascript">
google.charts.setOnLoadCallback(function() {
var data = google.visualization.arrayToDataTable({!!json_encode($data)!!});
var options = {!! json_encode($options) !!};
var formatter = new google.visualization.PatternFormat('{0}');
formatter.format(data, [0, 1]);
var material = new google.visualization.PieChart(document.getElementById('chart_{!! $id !!}'));
material.draw(data, options);
});
And indeed this enforces a kind of formatting, but unfortunately the information is shown as plain text, not as a clickable URL. It is a bit weird, since this is almost the same as the example in the documentation.
I searched the web for solutions, but most of them refer to deprecated API's.
Any help appreciated
Microsoft have announced it is possible to turn off the loading image shown when a report is loading.
Loading Image
Use the Power BI Embedded JavaScript SDK to hide the flickering Power
BI logo that appears when a report is loaded. - power-bi-embedded-feature-hide-the-power-bi-logo-during-visualization-load
However I cannot find any mention of this in any of the JS SDK documentation or any examples online.
Has anyone achieved this yet?
First add a gif which you want instead of the Power BI logo. You can add it in a div element. This element will overlap the div element containing the report. The HTML code looks like below:
<div id="container">
<div id="overlay">
<img id="spinner" alt="Alternate Text" src="image/giphy.gif"/>
</div>
<div id="embedContainer" style="height: 600px; width: 100%; max-width: 1400px;">
</div>
</div>
Once you have added your gif. Now, make changes in the JavaScript Code. So you final JavaScript embedding code will be:
<script type="text/javascript">
// Read embed token
var embedToken = "<% =this.embedToken %>";
// Read embed URL
var embedUrl = "<% = this.embedUrl %>";
// Read report Id
var reportId = "<% = this.reportId %>";
// Get models (models contains enums)
var models = window['powerbi-client'].models;
// Embed configuration is used to describe what and how to embed
// This object is used when calling powerbi.embed
// It can also include settings and options such as filters
var config = {
type: 'report',
tokenType: models.TokenType.Embed,
accessToken: embedToken,
embedUrl: embedUrl,
id: reportId,
settings: {
filterPaneEnabled: true,
navContentPaneEnabled: false
}
};
$("#embedContainer").css("visibility", "hidden");
// Get a reference to the embedded report HTML element
var reportContainer = $('#embedContainer')[0];
// Embed the report within the div element
var report = powerbi.embed(reportContainer, config);
report.on("loaded", function (event) {
$("#overlay").hide();
$("#embedContainer").css("visibility", "visible");
report.off("loaded");
})
</script>
You can also add CSS to align you gif with your report:
<style>
#container{
position:absolute;
width: 1400px;
height:600px;
}
#overlay{
position:absolute;
width:inherit;
height:inherit;
}
#spinner{
display: block;
margin-top:10%;
margin-left: auto;
margin-right: auto;
width:10%;
height: 10%;
}
</style>
Further, you can refer to the following youtube link: https://www.youtube.com/watch?v=YhjtunTmnbw. This video is by the Power BI official YouTube account. In this video, you can learn how to get white-labelled embedded analytics in your application with Power BI Embedded. Discover how to hide the Power BI logo until the loaded or the rendered event, and how to use a personalized logo for the loading phase.
What the recommended way to do this, even in the article you referenced, is -
1. Hide the iframe (or the div containing it)
2. Listen to either the loaded event when using (phased loading)[https://github.com/Microsoft/PowerBI-JavaScript/wiki/Phased-Embedding-API] or rendered otherwise
3. Show the div you hid before and voila - the embedded power bi is already loaded..
It is not currently possible to remove the PowerBI loading symbol. It would be great idea to suggest to input your own custom logo though
Using:
WKpdftohml version 0.12.3.2
PHPwkhtmltopdf version 2.2.0
Chart.JS version 2.5.0
I'm trying to print a line graph using the above libraries. I can reproduce a pdf using the shell command: wkhtmltopdf --javascript-delay 5000 " http://netdna.webdesignerdepot.com/uploads7/easily-create-stunning-animated-charts-with-chart-js/chartjs-demo.html" test2.pdf
So there is no problem with WKhtmltopdf.
The problem is when I do it in my app, using the PHPwkhtmltopdf library. I get a blank page.
From my research these are the things I tried:
Added 'javascript-delay' => 500 to Chart.JS options;
Added animation:{onComplete: function () {window.JSREPORT_READY_TO_START =true} to Chart.JS options;
Added <div style="width:800px;height:200;font-size:10px;"> to the parent div of canvas html tag
Added ctx.canvas.width = 800;ctx.canvas.height = 200; to javascript initialization of the chart.
Well nothing worked. I love Chart.JS and WKhtmltopdf, but if I can't print I'll have to drop one of them. Is there any solution?
This is my php code for the PHPwkhtmltopdf:
public function imprimir ($request, $response)
{
// include_once 'config/constants.php';
// include_once 'resources/auxiliar/helpers.php';
$folha = $_POST['printit'];
$variaveis = explode(',', $folha);
$nomeFicheiro = $variaveis[0];
$printName = substr($nomeFicheiro, 5);
if (isset($variaveis[2])) {
$_SESSION['mesNumero'] = $variaveis[2];
$_SESSION['mes'] = $variaveis[1];
} else {
$mesNumero = 0;
$mes = '';
}
ob_start();
if ($nomeFicheiro == 'printPpiam') {
require ('C:/xampp/htdocs/.../'.$nomeFicheiro.'.php');
} else {
require ('C:/xampp/htdocs/.../'.$nomeFicheiro.'.php');
}
$content = ob_get_clean();
// You can pass a filename, a HTML string, an URL or an options array to the constructor
$pdf = new Pdf($content);
// On some systems you may have to set the path to the wkhtmltopdf executable
$pdf->binary = 'C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf';
$pdf -> setOptions(['orientation' => 'Landscape',
'javascript-delay' => 500,
// 'enable-javascript' => true,
// 'no-stop-slow-scripts' => true]
]);
if (!$pdf->send($printName.'.pdf')) {
throw new Exception('Could not create PDF: '.$pdf->getError());
}
$pdf->send($printName.'.pdf');
}
# Update 1
Made a php file with the page output. Run it in the browser and the graph rendered. When I do it in the console it renders everything except the graph!
How can it be wkhtmltopdf renders the graphics in this page : http://netdna.webdesignerdepot.com/uploads7/easily-create-stunning-animated-charts-with-chart-js/chartjs-demo.html but not my own?!
# Update 2
After Quince's comment, I tried just turning the animations off, but I'm not sure on how to do that. I tried:
$pdf -> setOptions(['orientation' => 'Landscape',
'javascript-delay' => 500,
// 'window-status' => 'myrandomstring ',
'animation' => false,
'debug-javascript',
'no-stop-slow-scripts',
]);
But it fails.
Here's the code that works with wkhtmltopdf version 0.12.5:
chart.html

(function(setLineDash) {
CanvasRenderingContext2D.prototype.setLineDash = function() {
if(!arguments[0].length){
arguments[0] = [1,0];
}
// Now, call the original method
return setLineDash.apply(this, arguments);
};
})(CanvasRenderingContext2D.prototype.setLineDash);
Function.prototype.bind = Function.prototype.bind || function (thisp) {
var fn = this;
return function () {
return fn.apply(thisp, arguments);

};
function drawGraphs() {

"options":{}
}
);
}
window.onload = function() {
drawGraphs();
};
</script>
</body>
</html>
Run:
$ wkhtmltopdf chart.html chart.pdf:
Loading pages (1/6)
Counting pages (2/6)
Resolving links (4/6)
Loading headers and footers (5/6)
Printing pages (6/6)
Done
Found the answer. After I created a separate file, outside the framework, i did some tests again. It rendered the graph in the browser so I tried to use the command tool WKhtmltopdf, and it did not worked, when it did with other examples (see Update #1). So there is something wrong with my php page.
Ran the same tests that I did in the framework, and got the answer for my problem. By introducing a parent div tag width dimensions in the canvas tag it made the graph render in the page.
<div style="width:800px;height:200;">
<canvas id="myChart" style="width:800px;height:200;"></canvas>
</div>
The proposition was found in this site: Github, so thanks laguiz.
Try adding this, as according to this github source
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/7.0.0/polyfill.min.js"></script>
Solved it by downgrading wkhtmltopdf: 0.12.4 > 0.12.2.1
chart.js version seemed to have no influence. I used 2.7.0.
Fixed width and height seem to be required as well.
Edit: Since wkhtmltopdf is dead, I switched to Puppeteer recently.
I was dealing with the same issue using rotativa to export my ASP.NET MVC page with Chart.JS to PDF with no luck.
After a couple of days I finally found a super-easy solution to achieve my goal. What I did is simply to use the .toBase64Image() method of Chart.JS to encode the chart to a base64 string variable in Javascript. Then I saved this string into a model and then on the PDF html page a used tag where i put the base64encoded string to a scr property and the result is great :-)
javascript:
//save Chart as Image
var url_base64 = document.getElementById('myChart').toDataURL('image/png');
//set the string as a value of a hidden element
document.getElementById('base64graph').value = url_base64;
PDF view:
<img style='display:block; width:900px;height:400px;position:relative;margin:auto;text-align:center;' id='base64image'
src='#Model.base64graph' />
I'm trying to improve on the answer by temuri, which is great, but a bit bloated. I ran into the OP's issues (even same WKpdftohml version) and this did the trick for me:
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.8.0/Chart.min.js"></script>
<div style="width: 400px;"><canvas id="canvas"></canvas></div>
<script type="application/javascript">
// wkhtmltopdf 0.12.5 crash fix.
// https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3242#issuecomment-518099192
Function.prototype.bind = Function.prototype.bind || function (thisp) {
const fn = this;
return function () {
return fn.apply(thisp, arguments);
};
};
new Chart(
document.getElementById("canvas"), {
"responsive": false,
"type":"line",
"data":{"labels":["January","February","March","April","May","June","July"],"datasets":[{"label":"My First Dataset","data":[65,59,80,81,56,55,40],"fill":false,"borderColor":"rgb(75, 192, 192)","lineTension":0.1}]},
"options":{}
}
);
</script>
I'm yet to figure out how to get the chart library via ordinary tools like npm, instead of getting it via ajax like here in the first line. Note that this can impact your chart resolution.
I was strugling with that too and you self-answer did not help my case. I am using symfony 3.3 and Chart.js 2 and whatever I did, did not work properly. So I have solved it in a different manner (maybe not a clean one) and I wanted to post it here for inspiration to others.
I needed to export a page, that I was presenting to the user in a browser. In browser, I used Javascript to get picture out of the rendered graph with
animation: {
onComplete: function(animation) {
console.log('done');
var url=document.getElementById("barChartByCountryWeight{{ part }}{{ subsetKey }}").toDataURL();
$.ajax({
url: 'saveChartImages',
type: 'POST',
data: { 'barChartByCountryWeight{{ part }}{{ subsetKey }}': url },
success: function(result) {
console.log(result);
console.log('the request was successfully sent to the server');
},
error: function (request, error) {
console.log(arguments[0]['responseText']);
console.log(" Can't do because: " + error);
}
});
}
}
And on server side I put it in session and in a controller for the PDF export, I have taken the image from session and put the image in the HTML, that is converted to PDF.
Hope that helps.
I have implemented the working code for this issue. You can check out the working code here.
NOTE: For generating pdf you must disable the Chart JS animation or add the option javascript-delay=>1000 to the wkhtmltopdf options.
I have solved this problem when I tried to use Chartjs 1 instead of a new chart js. The reason for this is because laravel snappy uses wkhtmltopdf, which doesn't support css animation, while new chartjs uses css animation.
This github issue shows that.
The solution i found is to use google chart instead. It also uses svg, so you can get high resolution charts.
I'm using google geochart to display data.
My code:
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>
google.load('visualization', '1', { 'packages': ['geochart'] });
google.setOnLoadCallback(drawRegionsMap);
function drawRegionsMap() {
var geochart = new google.visualization.GeoChart(
document.getElementById('visualization'));
var options = {region: 'world', resolution: 'continents', width: 556, height: 347};
var data = google.visualization.arrayToDataTable([
['continents', 'Aircrafts'],
['Asia', 700]
]);
geochart.draw(data, options);
};
</script>
<div id="visualization" style="width: 800px; height: 400px;"></div>
In chart it doesn't show asia as data.
Although the 'continents' resolution option isn't in the official docs it does work. You need to change your data table to include a column of continent region codes, e.g.:
var data = google.visualization.arrayToDataTable([
['Region code', 'Continent', 'Aircraft'],
['142', 'Asia', 700]
]);
geochart.draw(data, options);
The region codes are required but don't get rendered in the tooltips. The codes matching each continent are explained here, beneath the options in the section called 'Continent Hierarchy and Codes'. It doesn't actually say you need to use them in your data table (that would be too easy...)
The only caveat is that I haven't yet found a way to get it to recognise the subregion codes that will allow separating 'Americas' into North & South. If you stick to using the continent codes then they should work - they do for me. Note that the codes need to be in the data table as strings.
See here for a working example : http://jsfiddle.net/6hrhj9qs/
You are using undocumented options described in this post
There it was also said that this bug would be fixed soon... and date was 5/25/11!
I didn't find other update.
Try using VectorWorkz' GeoChart, it supports Asia as a Continent and you have full control of the regions and add/modify the underlying maps to your needs. We can help create custom maps for you too.
