12.4 to generate a pdf,charts are drawn by chartist,because chartist is svg based. I can see the chart in browser by html(test-chartist.html right chart).But When I user the command wkhtmltopdf --dpi 300 --page-size A4 test-chartist.html test3.pdf, chart is blank in the test3.pdf. And then I add the flowing js , the result is weirdsize is not right and direction is not right too
Function.prototype.bind = Function.prototype.bind || function (thisp) {
var fn = this;
return function () {
return fn.apply(thisp, arguments);
};
};
can anybody help me? thank you very much
OK，I suddenly found out the answer.
If I add width and height to the chart's options, everything is fine, as below:
var options = {
width: 800,
height: 150,
donut: true,
donutWidth: 30,
startAngle: 240,
total: 30,
showLabel: true,
animation:false
};
new Chartist.Pie('#mainImg', {
series: [10,10]
},options);
I hope it can help others.

I'm using var imgUri = chart.getImageURI(); to get the image of the chart, but it's 400x200 and it kinda sucks, is there a way to increase it?
(thanks to Irvin Jay G. for the docs link)
I resolved by setting options as following:
var options = {
pointSize: 10,
width: 1920,
height: 1080,
vAxis: {minValue: minValue}
};
I am trying to change the border/background of an AnnotationChart from Google's Chart library. If I use the standard backgroundColor options, the chart fails to render. Per this discussion, it seems that the backgroundColor options available on other chart types aren't directly accessible on the AnnotationChart, but are available through undocumented options. When I try this, though, the chart is unchanged. Below is the code and resulting chart; any ideas?
Without chart option
var chart = new google.visualization.AnnotationChart(document.getElementById('chart_div'));
var options = {
thickness: 1.5,
displayAnnotations: true,
colors: dataColors,
displayZoomButtons: false,
displayExactValues: false,
displayDateBarSeparator: true,
};
chart.draw(data, options);
With:
var chart = new google.visualization.AnnotationChart(document.getElementById('chart_div'));
var options = {
thickness: 1.5,
displayAnnotations: true,
colors: dataColors,
displayZoomButtons: false,
displayExactValues: false,
displayDateBarSeparator: true,
chart: {
backgroundColor: {
fill:'black',
stroke: 'white',
strokeSize: 1
},
chartArea: {
backgroundColor: {
fill: 'blue',
stroke: 'red',
strokeSize: 1
}
}
}
};
chart.draw(data, options);
Either way, graph looks like this:
The background color can be set using it like this. Read the documentation here
Edit your code like this
var options = {
displayAnnotations: true,
displayZoomButtons: false,
displayExactValues: false,
displayDateBarSeparator: true,
chart: {
backgroundColor: 'blue',
chartArea: {
backgroundColor: '#FFF000',
},
},
fill: 50,
};
I tried using strokeWidth and stroke but I think it is not being supported yet or I am using it incorrectly.
Working JSFIDDLE
I've had my own issues with the lack of customization options for Google Charts and one workaround is to use Javascript to modify the SVG after it is generated in order to produce the look you want.
I've put together a quick fiddle based on the template Annotation Chart in the Google Charts Reference, but the applicable lines of code are below. It's not pretty (especially if you're using interactive charts, because this requires a MutationObserver to monitor the SVG for changes) but it works and you might be able to clean it up a lot more.
Note: I've noticed interactions with Google Charts (e.g. zooming and panning) tend to bog down a lot in JSFiddle and Codepen etc for some reason, but they're much smoother when used in the wild!

I'm graphing some lines on a c3.js line chart, but the data label of the leftmost point is being cut off:
I've tried adding padding to the chart, but this just adds padding to the overall chart. What I need is some way to add some sort of padding to just the bar graph ticks.
Something that I've considered:
I've considered using the "transform" property:
.c3-texts .c3-text text {
transform: translate(10px, 0);
}
But moving the position of all the data labels to the right would end up causing the data labels on the right-hand side of the graph to get cut off.
Here's a simple example of labels getting cut off:
fiddle
var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 400, 150, 250]
],
labels: {
format: function(x){
return "Test Label"
}
}
}
});
Any help would be appreciated. Thanks!
#ksav pointed me in the right direction. I remember trying this before, but foolishly, I didn't think of putting decimal numbers. I had tried putting in the value 1, and it gave way too much padding, but doing the following worked perfectly:
axis: {
x: {
padding: {
left: 0,
right: 0,
}
}
}
I started to learn C3.js. It is pretty good to work with.
I got stuck in this part, I hope anyone can help me to go forward .
How to create circle in outer of circle in line chart using c3.js .
This is my example code
var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 150, 150, 250],
['data12', 30, 200, 100, 150, 150, 250]
],
type: 'line'
},
});
It is giving one small circle ( Dot kind of ) but I want to create one more circle with different color and inside of that circle I need to show this small circle (Dot Kind of ) .
How to do that?
I have tried to select all circle and apply border for that .I have tried like this
d3.selectAll('circle').each(function(){
this.style('border-radius: 20px;');
});
this is wrong way, also this is not working. How to do that ?
Is it possible in c3.js?
You can set the size of your point using chart options
...
point: {
r: 20
}
...
and you can draw a border by using CSS
#chart .c3-circle {
stroke: black;
stroke-width: 4;
}
(assuming you are drawing the chart in a container with ID chart)
Fiddle - http://jsfiddle.net/yhz8k5k9/
I have a pie chart and I can add labels for it normal way.But I want to add labels with line as following.
I took this image from web as a example. here is my code ,
drawPieCharts = function(dev,title,data){
$('#'+dev).empty();
var plot = $.jqplot(dev, [data], {
title: {
text: title,
fontWeight: 'bold',
fontSize : '16',
show: true
},
grid: {
drawBorder: false,
drawGridlines: false,
background: '#ffffff',
shadow:false,
//diameter : 30
},
axesDefaults: {
},
highlighter: {
show: true,
formatString:'%s , P%',
tooltipLocation:'n',
useAxesFormatters:false
},
seriesDefaults:{
renderer:$.jqplot.PieRenderer,
rendererOptions: {
showDataLabels: true,
dataLabelThreshold: 0,
dataLabelPositionFactor: 1.05,
dataLabels : mapSeperater(data)[0],
padding: 2
}
},
});
}
And also I have another problem I want to bold the title of the chart and in this way it doesn't work. Is there a way to do that?
Thank you.
i'm looking for the same, not successful yet.
but for the title maybe you can try to style the div with the class "jqplot-title", that's where the title is rendered.
in jquery would be something like that:
$(".jqplot-title").wrap("<b></b>")
EDIT:
sorry i had no time to jsfiddle it, but you can try it and get the idea. looks a little awful but you can make it better.
what i did was putting labels of the slices outside the pie and draw some lines from the center to these labels.
..i came with something like this:
series: [{
renderer: $.jqplot.PieRenderer,
rendererOptions: {
diameter: 140,
showDataLabels: true,
dataLabelThreshold: 0, //minimum area to show a label, (i want all the labels)
dataLabelPositionFactor: 2.3, //in function of the radius, how far show the label
dataLabels: 'label',
dataLabelFormatString: '%s',
//(just more options, etc, etc)
plot = $.jqplot("myDivHere", [data], options).replot(); // <-- that's for me
// ******************************
// HERE COMES THE MAGIC:
//
var w = $("#myDivHere .jqplot-series-shadowCanvas").width();
var h = $("#myDivHere .jqplot-series-shadowCanvas").height();
x1 = (w/2);
y1 = (h/2);
var canvas = $("#myDivHere .jqplot-series-shadowCanvas")[0];
var context = canvas.getContext('2d');
$(".jqplot-pie-series.jqplot-data-label").each(
function(){
var l = $(this).position().left;
var t = $(this).position().top;
console.log("x1, y1 are: ["+x1+", "+y1+"]\n l, t are ["+l+", "+t+"]");
context.beginPath();
context.moveTo(x1, y1);
context.lineTo(l, t);
context.stroke();
});
I have no more time to work on this this week, so you could use it as awful it is and make it better. or wait for a better solution to show up.
Greetings!!
Ahh, and if you can make it better, please share it with me.
