Google Donut Chart

I ran into the problem of implementing graphics via google chart, it is necessary to make a three sectional diagram, please tell me how to do it better.
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Effort', 'Amount given'],
['My all', 100],
['My alsl', 100],
['My alsl', 100],
]);
var options = {
pieHole: 0.85,
tooltip: { trigger: 'none' },
pieSliceText: 'none',
pieSliceTextStyle: {
color: 'transparent',
},
legend: 'none',
slices: {
0: { color: '#f9b231' },
1: { color: '#7e430f' },
2: { color: '#f8d597' }
}
};
var chart = new google.visualization.PieChart(document.getElementById('donut_single'));
chart.draw(data, options);
}
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="donut_single" style="width: 900px; height: 500px;"></div>

Javascript charts as input

I have a requirement as below.
I need to input time series data (day data) using a graph. The data is usually like below but the profile can be changed depending upon the situation.
Right now the data is being manually entered in textboxes which makes it very difficult.
I am wondering whether there are solutions that let user draw on a chart and generate the data in the back. In other words, the user picks certain points and the profile is drawn.

see following working snippet, click on the chart to add a data point...
google.charts.load('current', {
callback: function () {
var data = new google.visualization.DataTable({
"cols": [
{"label": "x", "type": "number"},
{"label": "y", "type": "number"}
]
});
var axisMax = 10;
var ticks = [];
for (var i = 0; i <= axisMax; i = i + 0.5) {
ticks.push(i);
}
var options = {
chartArea: {
bottom: 64,
height: '100%',
left: 64,
top: 24,
width: '100%'
},
hAxis: {
format: '0.0',
textStyle: {
fontSize: 9
},
ticks: ticks,
title: data.getColumnLabel(0),
viewWindow: {
min: 0,
max: axisMax
}
},
height: 600,
legend: {
position: 'top'
},
pointSize: 4,
vAxis: {
format: '0.0',
textStyle: {
fontSize: 9
},
ticks: ticks,
title: data.getColumnLabel(1),
viewWindow: {
min: 0,
max: axisMax
}
}
};
var tableDiv = document.getElementById('table_div');
var table = new google.visualization.Table(tableDiv);
var chartDiv = document.getElementById('chart_div');
var chart = new google.visualization.LineChart(chartDiv);
var chartLayout = null;
google.visualization.events.addListener(chart, 'ready', function () {
chartLayout = chart.getChartLayoutInterface();
});
google.visualization.events.addListener(chart, 'click', function (sender) {
data.addRow([
chartLayout.getHAxisValue(sender.x),
chartLayout.getVAxisValue(sender.y)
]);
drawChart();
});
function drawChart() {
chart.draw(data, options);
table.draw(data);
}
window.addEventListener('resize', drawChart, false);
drawChart();
},
packages:['corechart', 'table']
});
div {
text-align: center;
}
<script src="https://www.gstatic.com/charts/loader.js"></script>

Google Charts only using first color

I am having trouble with Google Charts Bar Chart option to change colors of my bars - I have 3 bars and 3 colors listed in the options, but the bars are only showing the first color. Any ideas why?
function drawChart2() {
var chartdata = new google.visualization.arrayToDataTable([
['Vote Choice', 'Votes'],
[$scope.PropVotes[3].description, $scope.PropVotes[3].numVotes],
[$scope.PropVotes[4].description, $scope.PropVotes[4].numVotes],
[$scope.PropVotes[5].description, $scope.PropVotes[5].numVotes]
]);
var options = {
title: $scope.Propositions[1].Title,
legend: {
position: 'top'
},
colors: ['#002c58', '#69BE28', '#A5ACAF'],
chartArea: {
width: '100%',
height: '100%'
},
bars: 'horizontal',
animation: {
startup: true,
duration: 5000,
easing: 'linear'
}
};
var chartName = 'chart_div2'; //' + $scope.PropVotes.id;
var chart = new google.charts.Bar(document.getElementById(chartName));
chart.draw(chartdata, options);
}

Wrapping text of x-Axis Labels for Google Visualization Charts

I cannot seem to wrap my label for my column chart. I tried fiddling around with the options but it doesn't make any difference.
This is my current chart view, as you can see the label for column 2 has completely disappeared as the column 1 label has overlapped:
this is my Column Chart View:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1.1", { packages: ["bar"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var data1 = google.visualization.arrayToDataTable([
['Faculty Name', 'Book', 'Book Chapter', 'Journal Article', 'Conference'],
#Html.Raw(rows)]);
var options = {
title: '',
'width': 800,
'height': 500
};
var chart = new google.charts.Bar(document.getElementById('columnchart_material'));
chart.draw(data1, options);
}
</script>
<div id="columnchart_material" style="width: 800px; height: 500px;"></div>

You can reduce the font size down to 11 to get the label to show...
var options = {
'title': '',
'width': 800,
'height': 500,
'hAxis': {'textStyle': {'fontSize': 11}}
};
To do so, you will need to convert your options...
chart.draw(data1, google.charts.Bar.convertOptions(options));

you may draw a classical ColumnChart (when it is an option):
google.load("visualization", "1.1", {
packages: ["corechart"]
});
google.load("visualization", "1.1", {
packages: ["corechart"]
});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data1 = google.visualization.arrayToDataTable([
['Faculty Name', 'Book', 'Book Chapter', 'Journal Article', 'Conference'],
['Commerce, Law and Managment', 4, 9, 9, 1],
['foobar',2,2,2,3],
['Health Sciences', 0,2,3,1],
['Humanities', 0, 1, 1, 0],
['Science', 0, 0, 0, 1]
]);
var options = {
title: '',
'width': 800,
'height': 500,
vAxis: {
gridlines: {
count: 10
}
}
};
var chart = new google.visualization
.ColumnChart(document.getElementById('columnchart_material'));
chart.draw(data1, options);
}
<div id="columnchart_material" style="width: 800px; height: 500px;"></div>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>

Animate Google Chart from JSON

All of the examples on how to animate don't cover if the chart is created by JSON data. They all use static data. (See Transition Animation.)
This is my code that gets my data via JSON.
<script type="text/javascript">
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
$.post('/Weight/WeightAreaChartData', {}, function (data) {
var tdata = new google.visualization.arrayToDataTable(data);
var options = {
title: 'Weight Lost & Gained This Month',
hAxis: { title: 'Day of Month', titleTextStyle: { color: '#1E4A08'} },
vAxis: { title: 'Lbs.', titleTextStyle: { color: '#1E4A08' } },
chartArea: { left: 50, top: 30, width: "75%" },
colors: ['#FF8100'],
animation:{
duration: 1000,
easing: 'in'
},
};
var chart = new google.visualization.AreaChart(
document.getElementById('chart_div')
);
chart.draw(tdata, options);
});
}
</script>
I have a button that redraws the chart successfully. However, it doesn't animate. How can I make the chart animate? Thank you for your help.
$('#myBtn').click(function () {
drawChart();
});

Maybe cause you're creating the chart everytime?
Try to make chart a global variable and try again

As eluded to by #FelipeFonseca, you're overwriting the chart each time #myBtn is clicked. Try doing this instead:
(function (global, undef) {
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
var options = {
title: 'Weight Lost & Gained This Month',
hAxis: { title: 'Day of Month', titleTextStyle: { color: '#1E4A08'} },
vAxis: { title: 'Lbs.', titleTextStyle: { color: '#1E4A08' } },
chartArea: { left: 50, top: 30, width: "75%" },
colors: ['#FF8100'],
animation:{
duration: 1000,
easing: 'in'
}
};
var chart;
function drawChart() {
$.post('/Weight/WeightAreaChartData', {}, function (data) {
var tdata = new google.visualization.arrayToDataTable(data);
if (!chart) {
chart = new google.visualization.AreaChart(
document.getElementById('chart_div')
);
}
chart.draw(tdata, options);
});
}
})(this);
