I'm trying to draw a Google Line Chart but I've some problem drawing the second line. I'm using data from my MySQL database which allow me to display the sum amount of sold pieces grouped by months in 2018.
But I'd like to display the sum amount divided for every responsibility group which is a string value inside my every row.
This is my code:
<?php
$curyear = date('Y');
$con = mysqli_connect('xxxx','xxxx','xxxx','xxxx');
?>
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>

// Set a callback to run when the Google Visualization API is loaded.

// instantiates the pie chart, passes in the data and

function drawChart() {

var data = google.visualization.arrayToDataTable([
['Date', 'Pezzi',],
<?php
$query = "SELECT responsabile, sum(n_sim)+sum(n_accessi) as pezzi, data_dichiarato FROM dichiarati WHERE responsabile = 'ADMRZ01' and n_ragsoc != 'DICHIARATO ZERO' and YEAR(DATA_DICHIARATO) = '$curyear' GROUP BY MONTH(data_dichiarato) ORDER BY data_dichiarato";
$exec = mysqli_query($con,$query);
while($row = mysqli_fetch_array($exec)){
echo "['".date("M", strtotime($row['data_dichiarato']))."',".$row['pezzi']."],";
}
?>
]);
// Set chart options
var options = {'title':'SIM CONSEGNATE NEL <?php echo $curyear; ?>',
'width':1200,
'height':300
// isStacked: true
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>

So as you can see I have a single query which extracts data just for responsibility ADMRZ01. But in my database, I've rows with ADMRZ02, ADMRZ11, and others.
I'd like to have a line in Linechart for every responsibility I'm adding.
How can I modify my code?
Is it necessary to add another query? Or a Series?
I'm sorry I'm just a beginner in charts
Thanks
in order to have multiple lines / series,
the google data table will need to look something like the following...
var data = google.visualization.arrayToDataTable([
['Date', 'ADMRZ01', 'ADMRZ02', 'ADMRZ11'],
['Jan', 10, 20, 30],
...
]);
but this would very difficult to build from the query, without a bunch of hard-coding
instead, add a column for responsibility,
then we can use google data methods to transform the rows to columns.
to begin, the data table will look something like...
var data = google.visualization.arrayToDataTable([
['Date', 'Responsibility', 'Pezzi'],
['01/01/2018', 'ADMRZ01', 10],
['01/01/2018', 'ADMRZ02', 20],
['01/01/2018', 'ADMRZ11', 30],
['02/01/2018', 'ADMRZ01', 40],
['02/01/2018', 'ADMRZ02', 50],
['02/01/2018', 'ADMRZ11', 60],
['03/01/2018', 'ADMRZ01', 70],
['03/01/2018', 'ADMRZ02', 80],
['03/01/2018', 'ADMRZ11', 90],
]);
you'll want to keep the dates, because when we aggregate,
the month names will get sorted alphabetically, and will be out of order.
e.g. --> Apr, Aug, Dec, Feb, etc...
we can format as month name later.
first, change the query to include all responsibilities...
var data = google.visualization.arrayToDataTable([
['Date', 'Responsabile', 'Pezzi'],
<?php
$query = "SELECT data_dichiarato, responsabile, sum(n_sim)+sum(n_accessi) as pezzi FROM dichiarati WHERE n_ragsoc != 'DICHIARATO ZERO' and YEAR(DATA_DICHIARATO) = '$curyear' GROUP BY data_dichiarato, responsabile ORDER BY data_dichiarato";
$exec = mysqli_query($con,$query);
while($row = mysqli_fetch_array($exec)){
echo "['".$row['data_dichiarato']."','".$row['responsabile']."'".$row['pezzi']."],";
}
?>
]);
then you can use the following javascript to transform the rows to columns,
see following working snippet...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
// create data table
var data = google.visualization.arrayToDataTable([
['Date', 'Responsibility', 'Pezzi'],
['01/01/2018', 'ADMRZ01', 10],
['01/01/2018', 'ADMRZ02', 20],
['01/01/2018', 'ADMRZ11', 30],
['02/01/2018', 'ADMRZ01', 40],
['02/01/2018', 'ADMRZ02', 50],
['02/01/2018', 'ADMRZ11', 60],
['03/01/2018', 'ADMRZ01', 70],
['03/01/2018', 'ADMRZ02', 80],
['03/01/2018', 'ADMRZ11', 90],
]);
// create data view
var view = new google.visualization.DataView(data);
// column arrays
var aggColumns = [];
var viewColumns = [{
// convert string to date
calc: function (dt, row) {
return new Date(dt.getValue(row, 0));
},
label: data.getColumnLabel(0),
type: 'date'
}];
// build view & agg columns for each responsibility
data.getDistinctValues(1).forEach(function (responsibility, index) {
viewColumns.push({
calc: function (dt, row) {
if (dt.getValue(row, 1) === responsibility) {
return dt.getValue(row, 2);
}
return null;
},
label: responsibility,
type: 'number'
});
aggColumns.push({
aggregation: google.visualization.data.sum,
column: index + 1,
label: responsibility,
type: 'number'
});
});
// set view columns
view.setColumns(viewColumns);
// sum view by date
var aggData = google.visualization.data.group(
view,
[0],
aggColumns
);
// draw chart
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(aggData, {
title: 'SIM CONSEGNATE NEL...',
hAxis: {
format: 'MMM',
ticks: view.getDistinctValues(0)
}
});
});

note: jsapi should no longer be used to load the charts library,
according to the release notes...
The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. The last update, for security purposes, was with a pre-release of v45. Please use the new gstatic loader.js from now on.
this will only change the load statement, see above snippet...

I need help adding latest TimesStamp to page that displays Google gauge. I have made gauge work and auto refresh without the need to refresh the page, but now I need to display on it, or next to it when the latest entry in database was made (displaying TimesStamp of value that is currently displayed in gauge). Here's my code so far:
Chart.html
<!DOCTYPE html>
<html lang="en">
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<script src="https://www.gstatic.com/charts/loader.js"></script>
<script>
google.charts.load('current', {
packages: ['gauge']
}).then(function () {
var options = {
width: 800, height: 240,
greenFrom: 98, greenTo: 100,
yellowFrom:90, yellowTo: 98,
minorTicks: 5
};
var chart = new google.visualization.Gauge(document.getElementById('chart_div'));
drawChart();
function drawChart() {
$.ajax({
url: 'getdata.php',
dataType: 'json'
}).done(function (jsonData) {
// use response from php for data table
var data = google.visualization.arrayToDataTable(jsonData);
chart.draw(data, options);
// draw again in 5 seconds
window.setTimeout(drawChart, 5000);
});
}
});
</script>
</head>
<body>
<div id="chart_div" style="width: 800px; height: 240px;"></div>

</html>
And here's getdata.php
<?php
$servername = "localhost";
$username = "u644759843_miki";
$password = "plantaze2020!";
$dbname = "u644759843_plantazeDB";
// Create connection
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$conn = mysqli_connect($servername, $username, $password, $dbname);
$conn->set_charset('utf8mb4');
$sql = "SELECT ProductPurity FROM `Precizno ProductPurity` ORDER BY TimesStamp DESC LIMIT 1";
$result = mysqli_query($conn, $sql);
// create data array
$data = [];
$data[] = ["Label", "Value"];
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
$data[] = ["ProductPurity", (float) $row["ProductPurity"]];
}
mysqli_close($conn);
// write data array to page
echo json_encode($data);
?>
we need to include the timestamp in the data we return from php.
first, add the field to the select statement, here...
$sql = "SELECT ProductPurity, TimesStamp FROM `Precizno ProductPurity` ORDER BY TimesStamp DESC LIMIT 1";
next, we use a variable to save the timestamp...
// create data array
$data = [];
$data[] = ["Label", "Value"];
$stamp = null;
then, in the while loop, we save the value of the timestamp...
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
$data[] = ["ProductPurity", (float) $row["ProductPurity"]];
$stamp = $row["TimesStamp"]
}
finally, we combine both the chart data and timestamp in an object to send to the page.
$data = array('rows' => $data, 'timestamp' => $stamp);
following is the updated php snippet...
<?php
$servername = "localhost";
$username = "u644759843_miki";
$password = "plantaze2020!";
$dbname = "u644759843_plantazeDB";
// Create connection
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$conn = mysqli_connect($servername, $username, $password, $dbname);
$conn->set_charset('utf8mb4');
$sql = "SELECT ProductPurity, TimesStamp FROM `Precizno ProductPurity` ORDER BY TimesStamp DESC LIMIT 1";
$result = mysqli_query($conn, $sql);
// create data array
$data = [];
$data[] = ["Label", "Value"];
$stamp = null;
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
$data[] = ["ProductPurity", (float) $row["ProductPurity"]];
$stamp = $row["TimesStamp"]
}
mysqli_close($conn);
// write data array to page
$data = array('rows' => $data, 'timestamp' => $stamp);
echo json_encode($data);
?>
then on the html page, we need to adjust how we receive the data...
to receive the chart data, we need to use the 'rows' property from the data.
// use response from php for data table
var data = google.visualization.arrayToDataTable(jsonData.rows); // <-- add .rows
and we can receive the timestamp as follows...
jsonData.timestamp
not sure how you want to display the timestamp, here a <div> is used.
so to update the new <div> element...
document.getElementById('timestamp').innerHTML = jsonData.timestamp;
following the updated html snippet...
<!DOCTYPE html>
<html lang="en">

I have an MCU (ESP8266) with a temperature and humidity sensor.
The MCU sends the measurement data via MQTT to an MQTT broker running on my Synology NAS.
Also running on the NAS is an MQTT client (Node.js) that writes the received data to the MySQL database on the NAS.
Last but not least, a web server and PHP server are also running on the NAS.
Now I want to make a website to display the data from the db as a line chart.
Questions:
How can I populate Google line chart with data from mySQL database?
It's possible to use one single file (.php) to do this?
How can I manage a date range selection?
How can i select / deselect lines on the chart?
Here my answer to my question.
Since I have no big idea of the used programming languages, I had to search, read and test a lot of sources in the web to copy the result together :-)
I will extend it a bit in future, but for me it works perfectly.
I would like to present this solution here to help others get started.
However, there are certainly many ways to improve the code.
If someone wants to, I'd be happy about suggestions.

I don't understand how can insert the default variables (normal, desnutricion and desnutricion severa) with the baby variable.. I need to create a new table with the defaults data and then make a union? or just insert the variables in every series??

here the chart right now..
can you help me with my type of chart?

This is the basic framework you will need to make this work:
/*
* $normal is an array of (edad => peso) key/value pairs
* $desnutricion is an array of (edad => peso) key/value pairs
* $desnutricionSevera is an array of (edad => peso) key/value pairs
*
* you can hard-code these or pull them from a database, whatever works for you
*/
$sql = $conn->prepare("SELECT edad, peso FROM ESTATURA WHERE <criteria to select baby>");
$sql->execute();
$data = array(array('Meses', $apellido, 'Normal', 'Desnutricion', 'Desnutricion Severa'));
while($row = $sql->fetch(PDO::FETCH_ASSOC)) {
$edad = $row['edad'];
// use (int) to parse the value as an integer
// or (float) to parse the value as a floating point number
// use whichever is appropriate
$edad = (int) preg_replace('/\D/', '', $edad);
$peso = $row['peso'];
$peso = (float) $peso;
$data[] = array($edad, $peso, $normal[$edad], $desnutricion[$edad], $desnutricionSevera[$edad]);
}
Then, in your javascript:
function drawChart() {
var data = google.visualization.arrayToDataTable(<?php echo json_encode($data); ?>);
// sort the data by "Meses" to make sure it is in the right order
data.sort(0);
var options = {
title: 'Grafica de Crecimiento de niñas de 0 a 24 meses',
hAxis: {
title: 'Meses',
titleTextStyle: {color: '#333'}
},
vAxis: {
minValue: 0
},
series: {
0: {
// series options for this babys weight
type: 'line'
},
1: {
// series options for normal weight
type: 'area'
},
2: {
// series options for desnutricion
type: 'area'
},
3: {
// series options for desnutricion severa
type: 'area'
}
}
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
Give that a try and see if it works for you.
I am trying to fetch records from mysql and render the data via amchart, but I am facing difficulty in doing so. I have written the following code which is not working. The query works fine but the problem is replacing the static (placeholder) data with the results of the query. Please suggest.
{
$selectdata="SELECT member_lhp, COUNT( * ) AS 'land_pattern' FROM hh_basic_info GROUP BY member_lhp";
$resdata=mysql_query($selectdata);
<script type="text/javascript">
var chart;
var chartData = [
<?php
$count=0;
while($rowdata = mysql_fetch_assoc($resdata))
foreach($rowdata as $rows){
$type= $rows['member_lhp'];
$lp=$rows['land_pattern'];
if($count++ > 0) echo ',';
?>
{
year: <?php echo $type;?>,
income: <?php echo $lp;?>
},
<?php } ?>
];
AmCharts.ready(function () {
// SERIAL CHART
chart = new AmCharts.AmSerialChart();
chart.dataProvider = chartData;
chart.categoryField = "year";
// this single line makes the chart a bar chart,
// try to set it to false - your bars will turn to columns
chart.rotate = true;
// the following two lines makes chart 3D
chart.depth3D = 20;
chart.angle = 30;
// AXES
// Category
var categoryAxis = chart.categoryAxis;
categoryAxis.gridPosition = "start";
categoryAxis.axisColor = "#DADADA";
categoryAxis.fillAlpha = 1;
categoryAxis.gridAlpha = 0;
categoryAxis.fillColor = "#FAFAFA";
// value
var valueAxis = new AmCharts.ValueAxis();
valueAxis.axisColor = "#DADADA";
valueAxis.title = "Villagers - Land holding pattern";
valueAxis.gridAlpha = 0.1;
chart.addValueAxis(valueAxis);
// GRAPH
var graph = new AmCharts.AmGraph();
graph.title = "Income";
graph.valueField = "income";
graph.type = "column";
graph.balloonText = "Land holding number in [[category]]:[[value]]";
graph.lineAlpha = 0;
graph.fillColors = "#bf1c25";
graph.fillAlphas = 1;
chart.addGraph(graph);
// WRITE
chart.write("chartdiv");
});
</script>
}
At a quick glance it looks like you may have included an extra comma after your curly bracket. You are already adding a comma via the PHP if your count is greater than 0 so this would have been introducing a second, unnecessary one between each group of data.
You had the following...
{
year: <?php echo $type;?>,
income: <?php echo $lp;?>
},
try just having this instead...
{
year: <?php echo $type;?>,
income: <?php echo $lp;?>
}
It seems you forgot to parse in json format,
Just write
var newchartData= JSON.parse(chartData);
now assign newcharData to DataProvider,it should work.
