I'm styling a google chart using the javascript api. I want to change the background of the area where the data is plotted. For some reason when I set background options like so:
chart.draw(data, { backgroundColor: { fill: "#F4F4F4" } })
It changes the the background of the whole chart and not the area where the data is plotted. Any ideas on how to only change the background of the plotted area?
Thanks
pass the options like this
var options = {
title: 'title',
width: 310,
height: 260,
backgroundColor: '#E4E4E4',
is3D: true
};
add this to your options:
'chartArea': {
'backgroundColor': {
'fill': '#F4F4F4',
'opacity': 100
},
}
The proper answer is that it depends if it is classic Google Charts or Material Google Charts. If you use classic version of the Google Charts, multiple of the above suggestion work. However if you use newer Material type Google charts then you have to specify the options differently, or convert them (see google.charts.Bar.convertOptions(options) below). On top of that in case of material charts if you specify an opacity for the whole chart, the opacity (only) won't apply for the chart area. So you need to explicitly specify color with the opacity for the chart area as well even for the same color combination.
In general: material version of Google Charts lack some of the features what the Classic has (slanted axis labels, trend lines, custom column coloring, Combo charts to name a few), and vica versa: the number formating and the dual (triple, quadruple, ...) axes are only supported with the Material version.
In case a feature is supported by both the Material chart sometimes requires different format for the options.
<body>
<div id="classic_div"></div>
<div id="material_div"></div>
</body>
JS:
google.charts.load('current', { 'packages': ['corechart', 'bar'] });
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540],
['2009', 1120, 580],
['2010', 1200, 500],
['2011', 1250, 490],
]);
var options = {
width: 1000,
height: 600,
chart: {
title: 'Company Performance',
subtitle: 'Sales, Expenses, and Profit: 2014-2017'
},
// Accepts also 'rgb(255, 0, 0)' format but not rgba(255, 0, 0, 0.2),
// for that use fillOpacity versions
// Colors only the chart area, simple version
// chartArea: {
// backgroundColor: '#FF0000'
// },
// Colors only the chart area, with opacity
chartArea: {
backgroundColor: {
fill: '#FF0000',
fillOpacity: 0.1
},
},
// Colors the entire chart area, simple version
// backgroundColor: '#FF0000',
// Colors the entire chart area, with opacity
backgroundColor: {
fill: '#FF0000',
fillOpacity: 0.8
},
}
var classicChart = new google.visualization.BarChart(document.getElementById('classic_div'));
classicChart.draw(data, options);
var materialChart = new google.charts.Bar(document.getElementById('material_div'));
materialChart.draw(data, google.charts.Bar.convertOptions(options));
}
Fiddle demo: https://jsfiddle.net/csabatoth/v3h9ycd4/2/
It is easier using the options.
drawChart() {
// Standard google charts functionality is available as GoogleCharts.api after load
const data = GoogleCharts.api.visualization.arrayToDataTable([
['Chart thing', 'Chart amount'],
['Na Meta', 50],
['Abaixo da Meta', 22],
['Acima da Meta', 10],
['Refugos', 15]
]);
let options = {
backgroundColor: {
gradient: {
// Start color for gradient.
color1: '#fbf6a7',
// Finish color for gradient.
color2: '#33b679',
// Where on the boundary to start and
// end the color1/color2 gradient,
// relative to the upper left corner
// of the boundary.
x1: '0%', y1: '0%',
x2: '100%', y2: '100%',
// If true, the boundary for x1,
// y1, x2, and y2 is the box. If
// false, it's the entire chart.
useObjectBoundingBoxUnits: true
},
},
};
const chart = new GoogleCharts.api.visualization.ColumnChart(this.$.chart1);
chart.draw(data, options);
}
I'm using polymer that's why i'm using this.$.cart1, but you can use selectedbyid, no problem.
Have you tried using backgroundcolor.stroke and backgroundcolor.strokewidth?
See Google Charts documentation.
If you want to do like this then it will help. I use stepped area chart in the combo chart from the Google library...
where the values for each stepped area is the value for ticks.
Here is the link for jsfiddle code
Simply add background option
backgroundColor: {
fill:'red'
},
here is the fiddle link https://jsfiddle.net/amitjain/q3tazo7t/
You can do it just with CSS:
#salesChart svg > rect { /*#salesChart is ID of your google chart*/
fill: #F4F4F4;
}

I have a Google pie chart with the legend position set to labeled. My objective is to make all the text and legend marker lines black. Right now the lines are gray and so are the values-and-percentage numbers. Is there any way to make these all black?
var options = {
pieHole: 0.5,
pieSliceText: 'none',
textStyle:{color: 'black'},
legend: {position:'labeled', labeledValueText: 'both', alignment:'center',
textStyle: {
color: 'black',
fontSize: 12}, strokeColor: {color: 'black'},
},
};
Here is an example of the gray text and line marker I'm trying to make all black
Mutationobserver is what I needed since Google Charts have no built in commands to change these attributes.
var container = document.getElementById('pie_chart');
var chart = new google.visualization.PieChart(container);
chart.draw(view, options, observer);
var observer = new MutationObserver(function () {
$.each($('#pie_chart path[stroke="#636363"]'), function (index, path) {
$(path).attr('stroke', '#000000');
});
$.each($('#pie_chart path[fill="#636363"]'), function (index, path) {
$(path).attr('fill', '#000000');
});
$.each($('#pie_chart text[fill="#9e9e9e"]'), function (index, label) {
$(label).attr('fill', '#000000');
});
});
observer.observe(container, {
attributes: true,
childList: true,
subtree: true
});
And added this to the header.

I have to create a line chart, which has vertical bands in the background, and a vertical line at a specified position.Following is a sample chart image.
Sample chart
I tried to create a combo chart with line and bar as my series, to get the blue line and red vertical line. But i am unable to figure out how to get the vertical bands. Histogram is not supported by the combo chart. There is no option to create bar charts with variable width of each bar as well. Following is what i am able to create till now:
chart created so far
Following is my code:
function drawChart() {
// Some raw data (not necessarily accurate)
var data = google.visualization.arrayToDataTable([
['Percentile', 'Number of students', 'Vertical lines',{ role: 'style' }],
[1, 0.2020202,,''],
[3, 0.546875,,''],
[10, 1.20967742,,''],
[25, 1.87969925,,''],
[50, 1.953125, ,''],
[75, 1.32743363,,''],
[90, 0.64814815, ,''],
[97, 0.25316456, ,''],
[99, 0.00621891,,''],
[78, ,20,'stroke-width: 2; fill-color: red']
]);
var options = {
vAxis: {
gridlines:{count: 6},
viewWindow:{ max: 2.5}
},
hAxis: {
ticks: [0,20,40,60,80,100,120]
},
seriesType: 'line',
series: {1: {type: 'bars'}},
bar:{groupWidth:2},
intervals: { 'lineWidth':2, 'barWidth': 0.5, style: 'boxes' },
curveType: 'function',
legend: { position: 'none' },
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.ComboChart(document.getElementById('curve_chart'));
chart.draw(data, options);
}
</script>
Please suggest how can these vertical bands be achieved?
my chart looks like this img
and my options like this
var options =
{
height:'100%',
width: '100%',
legend: {position:'top'},
title: 'Celkový součet jednotlivých deficitů k roku 2015',
bars: 'vertical',
bar: {groupWidth: "80%"},
colors: ['#0079C1'],
vAxis:
{
title:'Počet',
format: 'decimal'
},
hAxis:
{
slantedText: true,
slantedTextAngle: 25,
title:'Deficit'
},
bars: 'vertical',
annotations: {
textStyle: {
color: '#000'
},
alwaysOutside: true,
style:'point'
},
chartArea: {
height: '60%'
}
};
My question is, can you rotate the annotation text verticaly so it doesn't get in the way of others if not is it possible to centre the annotation text to its column?
Another question is regarded to the hAxis you can see that my labels are quite long a i would prefer if some of the long labels broke into half and created a two line label.
Thank you very much for your responses nad sorry for my bad english
You can make the annotated text vertical by including annotations: {style: Line} in the chart options. This is shown in this jsfiddle. However, I haven't (yet) discovered how to center the annotations on the vertical bars.
Is there a way to create a Legend control for series that belong to Indicator Plot with Dojo Charting.
I've tried some standard well described ways from the documentation. But with no success! Legend are not appearing for Indicator Plot.
Maybe somebody know is it possible to draw legend for this case or not?
Thanks in advance!
EDIT(my code added):
1. id - id of chart dom element.
2. opts.chartOpts - chart options from outside js.
3. legname - id of legend dom element.
4. scale.avg - is just a double value.
this.chart = new Chart(id, this.opts.chartOpts);
this.chart.addPlot("default", {
animate: { duration: 1000, easing: easing.linear },
type: ColumnsPlot,
markers: true,
gap: 1
});
this.chart.addPlot("avgline", {
type: IndicatorPlot,
vertical: false,
lineStroke: { color: "#00ff00", style: "ShortDash" },
stroke: { width: '1.2px' },
fill: '#eeeeee',
font: 'normal normal normal 11px Arial',
labels: 'none',
offset: { x: 32, y: 4 },
values: [scale.avg],
precision: this.opts.precision
});
//Add axis code goes here... cutted for clearance
this.chart.addSeries('Power', chartOptions.data);
this.chart.addSeries('Average', [scale.avg], { plot: 'avgline' });
var tip = new Tooltip(this.chart, "default", { 'class' : 'kaboom' });
var mag = new Magnify(this.chart, "default");
var hightlight = new Highlight(this.chart, "default");
this.chart.render();
this.leg = new Legend({ chart: this.chart, horizontal: false }, this.legName);
And as result of this code I see legend for 'default' plot 'Power' series only. And nothing for 'Average' series.
I'm looking for a way to create what come to know to be called a "bubble chart" for a website I'm building. It needs to be compatible with IE7 and above, and of course all the good browsers like Firefox, Chrome and Safari. And no flash since this thing will need to run on iOS.
The chart needs to look like this, http://www.flickr.com/photos/jgrahamthomas/5591441300/
I've browse online and tried a few things, including:
Google Scatter Charts. This doesn't work as it seems Google Charts limits the size of a point to something smaller than I need. And Venn Diagrams are limited to three circles.
Protovis Dots. Great library, but isn't compatible with IE8.
Raphael Javascript. This one might be my best bet, but there's no explicit support for bubble charts.
Thanks for your help.
It looks like Raphael javascript is the way to go. It's compatible with IE6. I found a great tutorial at http://net.tutsplus.com/tutorials/javascript-ajax/an-introduction-to-the-raphael-js-library/ and am able to get the example working on my rails site with this code:
# window.onload = function() {
# var paper = new Raphael(document.getElementById('canvas_container'), 500, 500);
# var circle = paper.circle(100, 100, 80);
# for(var i = 0; i < 5; i+=1) {
# var multiplier = i*5;
# paper.circle(250 + (2*multiplier), 100 + multiplier, 50 - multiplier)
# }
# var rectangle = paper.rect(200, 200, 250, 100);
# var ellipse = paper.ellipse(200, 400, 100, 50);
# }
You can give Protovis a chance, the library looks good for your needs: http://vis.stanford.edu/protovis/ex/
Another charting library is Highcharts, but I haven't tried it yet: http://www.highcharts.com/
Have you had a look at flot?
It's a plotting library for jQuery. While it technically doesn't have any "native" support for bubble charts it is possible to create bubble charts with it by using a few tricks, the simplest one probably being to simply put each point in its own data series (thus allowing you to control the radius of each individual point.
By defining your points similar to this you'll be able to create a bubble chart:
var dataSet = [{
color:"rgba(0,0,0,0)", // Set the color so it's transparent
shadowSize:0, // No drop shadow effect
data: [[0,1],], // Coordinates of the point, normally you'd have several
// points listed here...
points: {
show:true,
fill:true,
radius: 2, // Here we set the radius of the point (or rather, all points
// in the data series which in this case is just one)
fillColor: "rgba(255,140,0,1)", // Bright orange :D
}
},
/* Insert more points here */
];
There is a bubble chart available for flot here
Note that you need to scale your bubbles size yourself if you don't want them to coverup the graph. Documentation is here.
To use it, add the following at the beggining of your html page:
and call it from a json result or any data object like in this sample:
$.getJSON('myQuery.py?'+params, function(oJson) {
// ... Some validation here to see if the query worked well ...
$.plot('#myContainer',
// ---------- Series ----------
[{
label: 'Line Sample',
data: oJson.lineData,
color: 'rgba(192, 16, 16, .2)',
lines: { show: true },
points: { show: false }
},{
label: 'Bubble Sample',
data: oJson.bubbleData, // arrays of [x,y,size]
color: 'rgba(80, 224, 80, .5)',
lines: { show: false },
points: { show: false },
},{
label: 'Points sample',
data: oJson.pointsData,
color: 'rgba(255, 255, 0, 1)',
lines: { show: false },
points: { show: true, fillColor: 'rgba(255, 255, 0, .8)' }
},{
...other series
}],
// ---------- Options ----------
{ legend: {
show: true,
labelBoxBorderColor: 'rgba(32, 32, 32, .2)',
noColumns: 6,
position: "se",
backgroundColor: 'rgba(224, 224, 224, .2)',
backgroundOpacity: .2,
sorted: false
},
series: {
bubbles: { active: true, show: true, fill: true, linewidth: 2 }
},
grid: { hoverable: true, clickable: true } },
xaxis: { tickLength: 0 }
}); // End of plot call
// ...
}); // End of getJSON call
I tried to do the same thing with jqPlot which has some advantages but doesn't work with bubbles and other kind of series on the same graph. Also Flot does a better job to synchronise common axis scale with many series. Highchart does a really good job here (mixing bubble chart with other kind of series) but isn't free for us (government context).
