I try to add a trendline to my Google LineChart. It just doesn't show up, without any hints why not in my browsers console.
Just copied the option setting from Googles examples. The table data are getting loaded via ajax, I disabled it and added a static string instead for the example.
I thought that I may have do define a series, but I can't really understand what a series is, and how do define one; my inital thought was that it's getting recognised automatically.
My code:
/* global google */
google.charts.load('current', {'packages': ['gauge', 'corechart', 'line']});
google.charts.setOnLoadCallback(drawAll);
function drawAll() {
drawTrendlines();
}
var temp_line;
function drawTrendlines() {
var line_data = jsonString;
function ajaxLines() {
console.log("updated lines");
temp_line.setDataTable(jsonString);
temp_line.draw();
setTimeout(ajaxLines, 60 * 1000);
}
var data = new google.visualization.DataTable(line_data);
var options = {
lineWidth: 3,
trendlines: { 0: {} },
height: 400,
hAxis: {
title: 'Zeit',
titleTextStyle: {
color: '#cccccc'
},
baselineColor: '#cccccc'
},
vAxis: {
title: 'Temperatur',
minValue: 20,
maxValue: 29,
titleTextStyle: {
color: '#cccccc'
},
baselineColor: '#cccccc'
},
colors: ['#AB0D06', '#007329'],
curveType: 'function',
backgroundColor: '#000'
};
temp_line = new google.visualization.ChartWrapper({
chartType: 'LineChart',
dataDataTable: data,
options: options,
containerId: 'temp_line'
});
temp_line.draw();
ajaxLines();
}
//Those data will be loaded via ajax when running on server

Thank you in advance.
trendlines are only supported by a continuous x-axis (number, date, etc...)
not a discrete axis (string values)
see following working snippet,
a data view is used to convert the first column to a real date
google.charts.load('current', {
packages: ['gauge', 'corechart', 'line']
}).then(drawTrendlines);
var temp_line;
function drawTrendlines() {
var line_data = jsonString;
function ajaxLines() {
temp_line.setDataTable(view);
temp_line.draw();
setTimeout(ajaxLines, 60 * 1000);
}
var data = new google.visualization.DataTable(line_data);
var view = new google.visualization.DataView(data);
view.setColumns([{
calc: function (dt, row) {
var today = new Date();
var value = dt.getValue(row, 0).replace(' ', '').split(',');
var valueDate = value[0].split('.');
var valueTime = value[1].split(':');
var newValue = new Date(today.getFullYear(), valueDate[1], valueDate[0], valueTime[0], valueTime[1]);
return newValue;
},
label: data.getColumnLabel(0),
type: 'date'
}, 1]);

I am displaying pie-chart as a tootip inside a column chart using google charts.
In the pie-chart, I want to do legend: { position: 'labeled' }, but it is not displaying the bars of the Column chart, and so cannot display the Pie chart.
It is only displaying the gridlines.

When I do legend: { alignment: 'center' } in the 'tooltipOptions', the Column chart and the Pie-chart is displaying correctly.
But I want to do 'legend: { position: 'labeled' }', as the Pie-Chart slices is not displaying the percentage for small values.
Try passing the following to your options:
pieSliceTextStyle: {
color: 'white',
fontSize: '13',
top: 10,
left: 50,
position: 'start',
},
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);
}

I'm trying to dynamically display some Google Charts in HTML using JavaScript and the Google Chart API but it doesn't seem to be loading at all.
The page simply displays my text field and nothing else, and even the text field onblur event isn't alerting me in the browser.
Below is the code that I am using...
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
function test() {
alert("TEST OUTPUT");
}
var chart_data = google.visualization.arrayToDataTable([
['Days', 'Sales', 'Cheeky', 'test'],
['19/07/2016', 10, 5, 3],
['20/07/2016', 5, 4, 2],
['21/07/2016', 15, 3, 1],
['22/07/2016', 2, 1, 2]
]);
var startdate = "20/07/2016";
var enddate = "21/07/2016";
google.charts.load('current', {'packages':['corechart']});
google.setOnLoadCallback(load_page_data);
function load_page_data(){
$.ajax({
url: 'get_data.php',
data: {'startdate':startdate,'enddate':enddate},
async: false,
success: function(data){
if(data){
chart_data = $.parseJSON(data);
drawChart(chart_data, "My Chart", "Data");
}
},
});
}
function drawChart(chart_data, chart1_main_title, chart1_vaxis_title) {
var chart1_data = new google.visualization.DataTable(chart_data);
var chart1_options = {
title: chart1_main_title,
vAxis: {title: chart1_vaxis_title, titleTextStyle: {color: 'red'}, minValue: 0, gridlines: { color: '#AC935D'} }
hAxis: {title: 'Year', titleTextStyle: {color: '#333'}},
backgroundColor:{fill: 'transparent'},
colors: ['#87734A', 'red', 'black'],
};
var chart1_chart = new google.visualization.AreaChart(document.getElementById('chart1_div'));
chart1_chart.draw(chart1_data, chart1_options);
}
</script>
</head>
<body bgcolor="#E2C17A">

</html>
What am I doing wrong?
you're missing a comma after the vAxis key in chart1_options
also, you can reference google.visualization anywhere in your code,
but only after the load callback has fired
try setting up your code something like this,
breaking down those long key: value pairs will help identify typos
google.charts.load('current', {
callback: function () {
$.ajax({
url: 'get_data.php',
data: {
'startdate': startdate,
'enddate': enddate
},
async: false,
success: function(data) {
if (data){
drawChart($.parseJSON(data), "My Chart", "Data");
}
}
});
function drawChart(chart_data, chart1_main_title, chart1_vaxis_title) {
var chart1_data = new google.visualization.DataTable(chart_data);
var chart1_options = {
title: chart1_main_title,
vAxis: {
title: chart1_vaxis_title,
titleTextStyle: {color: 'red'},
minValue: 0,
gridlines: {
color: '#AC935D'
}
},
hAxis: {
title: 'Year',
titleTextStyle: {
color: '#333'
}
},
backgroundColor: {
fill: 'transparent'
},
colors: ['#87734A', 'red', 'black']
};
var chart1_chart = new google.visualization.AreaChart(document.getElementById('chart1_div'));
chart1_chart.draw(chart1_data, chart1_options);
}
},
packages:['corechart']
});
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);
