android-plot bar chart from mysql database
I need a solution for this problem. Currently I had follow this video https://www.youtube.com/watch?v=EBGdWPBdfPo&t=104s. I need to plot using my own data. I already save the data from mysql to php but I do not know how to display the data in my android studio. Please help me.
This is my php code:
<?php
require_once 'connect.php';
//checking if any error occured while connecting
if(mysqli_connect_errno()){
echo "Failed to connect to MySQL: " . mysqli_connect_error();
die();
}
//creating a query
$stmt = $conn->prepare("SELECT AVG(rb_fd),AVG(rb_check_in),AVG(rb_check_out),AVG(rb_room),AVG(rb_staff),AVG(rb_navigation),AVG(rb_fs),AVG(rb_decor),AVG(rb_facilities),AVG(rb_wifi) FROM rating;");
//executing the query
$stmt->execute();
//binding result to the query
$stmt->bind_result($rb_fd,$rb_check_in,$rb_check_out,$rb_room,$rb_staff,$rb_navigation,$rb_fs,$rb_decor,$rb_facilities,$rb_wifi);
$rating = array();
//traversing throung all the result
while($stmt->fetch()){
$temp = array();
$temp['FD'] = $rb_fd;
$temp['CI'] = $rb_check_in;
$temp['CO'] = $rb_check_out;
$temp['R'] = $rb_room;
$temp['S'] = $rb_staff;
$temp['N'] = $rb_navigation;
$temp['FS'] = $rb_fs;
$temp['D'] = $rb_decor;
$temp['F'] = $rb_facilities;
$temp['W'] = $rb_wifi;
array_push($rating, $temp);
}
//displaying the result in json format
echo json_encode($rating);
?>
This is the output when I check at Postman:
[
{
"FD": 2.5,
"CI": 2.5,
"CO": 2.6666666666666665,

you have gotten data to PHP. but PHP is running on your server. you need to present it in a format (e.g. JSON) so that you can fetch it from your android application via a http call, then you can display it.

you have gotten data to PHP. but PHP is running on your server. you need to present it in a format (e.g. JSON) so that you can fetch it from your android application via a http call, then you can display it.
