javascript for loop google charts - javascript

I'm trying to build a javascript function to build some graphs using google charts on my webpage.
This is what I have done.
<script type="text/javascript">
google.load("visualization", "1.1", {packages: ["bar"]});
google.setOnLoadCallback(drawStuff);
function drawStuff() {
var data2 = <?php echo json_encode($final_array); ?>;
for(i=0;i<data2.length-1;i++) {
console.log(data2[i]);
var name = 'data'+i;
name = new google.visualization.arrayToDataTable([
['', ''],
["$50", data2[i]['calc']['savings']],
["$54", 31],
["$10", 12],
["$11", 10],
['$31', 3]
]);
var optionsname = 'options'+i;
optionsname = {
width: 150,
legend: {position: 'none'},
// chart:
axes: {
x: {
0: {side: 'top'}
// Top x-axis.
}
},
bar: {groupWidth: "90%"}
};
var chartname = 'chart'+i;
chartname = new google.charts.Bar(document.getElementById('columnchart_material.'+i));
// Convert the Classic options to Material options.
chartname.draw(name, google.charts.Bar.convertOptions(optionsname));
}
};
</script>
Since the data is in an array and I need to display it on multiple places within the same page, I've used for loop. All the variable names are generated properly and as per the guidelines. But at any point I'm able to see only one instance of the graph on the page. How do I overcome this?

Creating Table in Google App Script With Date Column

I am currently querying a table from Google sheet which has a Date column. The date column in my dashboard has time info included, which I want to remove; also the starting date in my code is 12/18/2018 but my dashboard starts with one day earlier. 12/17/2018 16.00
My Data source looks like this:

May I know how to change my date to the right format removing the time and also ensure the correct starting date
Any help is much appreciated.
The actual problem has me stumped, but I do have a workaround; see modified code example below, with some additional error handling.
I've extensively tested the server-side function, and from its perspective there is absolutely no difference in the row object that is created whether the range starts at column 'I' or 'J'.
The problem manifests itself in the client-side success handler which, when column 'I' is included is essentially passed a null argument, note the whole object, not just the row.data1 part, is null.
The row object that is being passed from the server to the client is quite complicated (an object with 3 key value pairs, where the values are fairly long arrays). I can't see anything in the GAS documentation that disallows this: Legal parameters and return values are JavaScript primitives like a Number, Boolean, String, or null, as well as JavaScript objects and arrays that are composed of primitives, objects and arrays. So this could be a bug?
The workaround, illustrated in the code examples below is to stringify the object in the server-side function, and then parsing it back to an object in the client.

Plotly.js traces not showing

I'm trying to use Plotly.js to create some graphs of historical cryptocurrency prices, and am running into the problem that my data is not showing up on the graph created. I'm building my code from the sample code at https://plot.ly/javascript/ajax-call/ but tooling it for my own data source and a local copy of plotly-latest.min.js. I'm using a small subset of my data and only one trace to get the code functional, and I've placed console.log statements after the processing of the data and the creation of the trace that show me my data is properly formatted judging by the sample code and its dataset. I've set the range of the chart to the range of my data, but I still see nothing on the chart when its created despite modeling it after working sample code. Where am I going wrong?
My code:
<!DOCTYPE html>

function makePlot() {
Plotly.d3.csv("bitcoin.csv", function(data){ processData(data) } );

function processData(allRows) {
var Date = [], Open = [], High = [], Low = [], Volume = [], MarketCap = [];
for (var i=0; i<allRows.length; i++) {
row = allRows[i];
tmpDate = row['Date;Open;High;Low;Close;Volume;MarketCap'].split(';')[0]
Date.unshift( tmpDate.split('/')[2] + '-' + tmpDate.split('/')[1] + '-' + tmpDate.split('/')[0]);

I guess it should be your variable traces causes the problem
var traces = [{
x: Date, //not Date: Date
y: Open //not Open: Open
}];

Number format of axis - Google Gauge

I am trying to change the number format of the axis on a google gauge. By default, the axis value is a whole number (e.g. 0, 120) but I would like to show a £ sign and format as currency (e.g. £0, £120). I have been able to change the format of the value shown at the bottom of the gauge using NumberFormat but cannot apply to the rest of the gauge.The code for the basic gauge is as follows:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['gauge']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data1 = google.visualization.arrayToDataTable([
['Label', 'Value'],
['Spend', 80],
]);
var options1 = {
width: 500, height: 300
};
// change number format to £
var formatter = new google.visualization.NumberFormat(
{pattern: '£###,###'});
formatter.format(data1, 1);
var chart = new google.visualization.Gauge(document.getElementById('chart_div1'));
chart.draw(data1, options1);
}
</script>
</head>
<body>
<div id="chart_div1"></div>
</body>
</html>
How do I add a £ sign to the numbers on the outside of the gauge? Thank you.
You can provide an array of strings to majorTicks to specify your own...
google.charts.load('current', {'packages':['gauge']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data1 = google.visualization.arrayToDataTable([
['Label', 'Value'],
['Spend', 80],
]);
var options1 = {
width: 500, height: 300,
majorTicks: [
'£0', '', '', '', '£100'
]
};
// change number format to £
var formatter = new google.visualization.NumberFormat({
pattern: '£###,###'
});
formatter.format(data1, 1);
var chart = new google.visualization.Gauge(document.getElementById('chart_div1'));
chart.draw(data1, options1);
}

create multilevel donut chart with Google Chart

I am creating a multilevel donut chart with google charts.
I am successful to creating a single level chart. But now I have to create another chart in that chart.
Please help me. And also is that possible to write text on chart slice in circular form?
here is my code for single donut chat.
HTML
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<div id="donutchart" style="width: 900px; height: 500px;"></div>
JS
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
['Work', 11],
['Eat', 2],
['Commute', 2],
['Watch TV', 2],
['Sleep', 7]
]);
var options = {
title: 'My Daily Activities',
pieHole: 0.4,
chartArea:{left: '100'},
pieSliceText: 'label',
pieStartAngle: 0,
pieSliceTextStyle:{color: 'white', fontName: 'arial', fontSize: 10}
};
var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
chart.draw(data, options);
}
and here is code link in JsFiddle
IT should be look like
This was possible with the Google Image Charts API, which has been deprecated in 2012. It seems to still be up and running, it's just not maintained anymore.
With that API, it was (and still is) possible to create concentric pie charts such as the one below
http://chart.apis.google.com/chart?chd=s:Yr3,ff9&cht=pc&chs=300x200&chxr=0,20,45|1,25,50
which yields the following pie chart
Also you can play with the API and easily create your own pie charts here:
http://www.jonwinstanley.com/charts/
Supporting this kind of concentric Pie chart in the new Google Charts API is still an open issue
I know it's has been a long time ago but here's one way you can do this, using google charts:
But, I removed the subtitles because they interfere in the position of objects, i think it's easier and better if we do our subtitles . Then i just made some drawings e maths to achieve this.
You can control the size and pieHole with 3 variables.
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
//control is here
let larguraGraficoFora = 400;
let alturaGraficoFora = 400;
let furoGraficoFora = 0.6;
var data = google.visualization.arrayToDataTable([
['Sabor de Pizza', 'Quantidade'],
['portuguesa', 30],
['frango com catupiry', 30],
['calabresa', 30],
['alguma doce', 30],
]);
var options = {
width: larguraGraficoFora,
height: alturaGraficoFora,
chartArea:{left:0,top:0,width:'100%',height:'100%'},
pieHole: furoGraficoFora,
legend: 'none'
};
var chart = new google.visualization.PieChart(document.getElementById('donut_1'));
chart.draw(data, options);
var data2 = google.visualization.arrayToDataTable([
['Effort', 'Amount given'],
['python', 20],
['c#', 20],
['javascript', 20],
['php', 20],
['sql server', 20],
]);
var options2 = {
legend:'none',
width: larguraGraficoFora*furoGraficoFora,
height: alturaGraficoFora*furoGraficoFora,
chartArea:{left:0,top:0,width:'100%',height:'100%'},
backgroundColor: 'transparent',
legend: 'none'
};
var chart2 = new google.visualization.PieChart(document.getElementById('donut_2'));
chart2.draw(data2, options2);
ajustePosicaoPieCentral(larguraGraficoFora, alturaGraficoFora, furoGraficoFora);
}
function ajustePosicaoPieCentral(largura, altura, furo){
yt = altura*(1+furo)/2.0;
xt = largura*(1-furo)/2.0;
var css = document.getElementById('donut_2');
css.style.transform = "translate("+xt+"px, -"+yt+"px)";

How to connect two points in Google Chart Tools - Scatter Chart

I use Google Chart Tools to draw simple graph with some missing data. With my code, I get something like on this image:
Is it possible to connect points (1) and (4) with line similar to (4) - (5) connection? Maybe I could use another type of graph to achieve the same result? I tried Area Chart with interpolateNulls option, but the result was the same. It can interpolate only NULLs surrounded by some date, not two or more NULLs in a row.
Below is sample code:
google.load('visualization', '1.0', {'packages':['corechart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Year');
data.addColumn('number', 'Sales');
data.addRows([
[1, 1000],
[2, null],
[3, null],
[4, 1030],
[5, 1080]
]);
var options = {
'title' : 'Line chart',
'width' : 400,
'height' : 300,
'lineWidth' : 2
};
var chart = new google.visualization.ScatterChart(document.getElementById('chart_div'));
chart.draw(data, options);
}

The answer to your question was on one of the comments:
'If the value you are trying to pass is through some xml or json and it has null values inside it will not plot properly and will be scattered or as dotted lines in line graph so to plot them, have a condition to remove all null values and then it will plot correctly.' by #Taher SK
