My vertical labels in the graph are getting cut off.
Is there a way to set/increase the label width?
Please see the image below.
The left hand labels need more width. (Y axis labels)

To do it automatically, you'll need to measure the text and allocate sufficient room. You might try an approach similar to this. Alternately, you could add a property for label size in the formatting pane and let your users override the default.

I'm trying to adapt https://www.chartjs.org/docs/latest/samples/bar/floating.html to create a kind of timeline chart, where the horizontal axis (the range data) are timestamps. Unfortunately I can't seem to get the data to display, and don't see any error messages, etc.

I am using a google timeline similar to the code snippet below. I want my chart to look like the one below. I have managed to get everything to work expect how to add the dashed lines and text notation. Unfortunately, when I am searching for annotations I keep getting the AnnotatedTimeline, which is a different google chart.
Is there a simple way to do this?

I was able to get this to work by finding the position of the rects. I started by drawing divs for each line I would want to show. Then after the timeline is draw I repositions those divs based on the location of the rectangle. I was not able to get a good minimal working snippet here because of the window positions used in the snippet code, but I got pretty close. In my own code I have it working perfectly.

I have tried multiple examples online, but nothing changes the standard tooltip.. I get a tooltip but it's not the one I want. Also when I try to console out the tooltip function, nothing comes..
I tried also made sure to use the latest apext charts
this is how I render the component:-

I have a Google Geochart that is connected to a Google Spreadsheet. The aim of the chart is to show different categories of universities in our state and their locations. I have assigned values in the spreadsheet in order to have the appropriate marker color for the map to denote the categories.
My problem is that the text denoting the type (a number) is showing in the tooltip. (Example: tooltip shows "ABC University Type 3." I need to either hide this text, or create a string based on conditional logic so that, for example, Type 3 translates to "XYZ System" in the tooltip. Which do you think is the better way to do it, and can you provide guidance as to how to do this?

You can use the DataView Class to change the formatted value of the Type column.
For instance, the value of the Type column in the DataTable looks like this...
{"v":3.0,"f":"3"}
With the DataView, change it to this...
{"v":3.0,"f":"XYZ System"}
We can also remove the column Label, to avoid seeing it in the tooltip.
See following example...
google.charts.load('current', {
callback: drawMap,
packages: ['geochart']
});
function drawMap() {
var query = new google.visualization.Query("https://docs.google.com/spreadsheets/d/1m3ujxzPQJh3haReNDzGGF73Mh6-u6HxyCVPK_5MK2hw/gviz/tq?sheet=Sheet3");
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
var data = response.getDataTable();

var schoolTypes = [
'ABC System',
'LMO System',
'XYZ System'

// create DataView from DataTable
var view = new google.visualization.DataView(data);
// set view columns, keep first three columns
// use calculated column for Type
view.setColumns([0, 1, 2, {
type: 'number',

calc: function (dataTable, rowIndex) {
return {
v: dataTable.getValue(rowIndex, 3),
// get school type from array

}
}
}]);
var options = {

<p>export to pdf</p>
</body>
I need create pdf export and add into image with gener graph. Berofe I must save render image. I try use method .toBase64Image() but I dont know have can I start.
My proceed
create canvas_link (.toDataUrl). After click save as image I can greate and upload image to server. Then I can generate pdf export (across mPDF) and to add imageto into export. This i can create, but I dont know create and upload image of graph to server.
I need more examples from http://www.chartjs.org/docs/
in that case you don't need to upload as an image.
you could put the result of the call to toDataUrl function in the value of a hidden field and send it in a form (with an iframe as target) or by an ajax call
use the following options in the chart
//new options var
var options = {
bezierCurve : false,
//animation: false
onAnimationComplete: done
};
//your code with a little modification
$(document).ready(
function () {
var ctx = document.getElementById("myChart").getContext("2d");
//use the previously defined "options" here!!!
var myNewChart = new Chart(ctx).Pie(data, options);
}
);
//callback function, called when the pie ends his animation
function done(){
//this part of your code was moved here to avoid that store an empty image
document.getElementById("canvas_link").src = document.getElementById("myChart").toDataURL();
var postdata={
file: document.getElementById("myChart").toDataURL()
}
$.post( "store.php", postdata)
.done(function( ret ) {
console.log( "Data status: Loaded successfully ");
})
.fail(function( ret ) {
console.log( "Data status: error ");
})
;
}
Reference: http://api.jquery.com/jquery.post/
in php you can handle the content in this way
// file: store.php
// Interpret data uri
$uriPhp = 'data://' . substr($file, 5);
// Get content
$binary = file_get_contents($uriPhp);
$file = 'uploads/charts/'. time() .'.png';
// Save image
file_put_contents($file, $binary);
Reference: https://github.com/nnnick/Chart.js/issues/99#issuecomment-75359927
As per the documentation, you can print or save graph by API calls;
Example
var chart = new CanvasJS.Chart("chartContainer", {
theme: "theme2",
title:{
text: "Print Chart using print() method"
},
data: [
{
type: "column",
dataPoints: [
{ label: "apple", y: 10 },
{ label: "orange", y: 15 },
{ label: "banana", y: 25 },
{ label: "mango", y: 30 },
{ label: "grape", y: 28 }
]
}
]
});
