Highcharts multiple rowsUrl in same charts - highcharts

How can I show multiple series with rowsUrl?
Example fiddle: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/data/livedata-rows
Highcharts.chart('container', {
chart: {
type: 'spline'
},
title: {
text: 'Live Data (Rows JSON)'
},
subtitle: {
text: 'Data input from a remote JSON file'
},
data: {
rowsURL: 'https://demo-live-data.highcharts.com/time-rows.json',
firstRowAsNames: false,
enablePolling: true
}
});
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/data.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

Use seriesMapping property:
data: {
...,
seriesMapping: [{
x: 0,
y: 1
}, {
x: 0,
y: 2
}]
}

get page to match highcharts style

I'm a css novice... I have a chart that looks great and an HTML table that looks very basic. I want the table to match the style of the chart (font, font size, etc.).
I've included the highcharts.css file in the head of the HTML and added styledMode: false to the charge definition.
<head>
<link rel="stylesheet" type="text/css" href="code/css/highcharts.css">

Highchart shows blank page using Codeigniter

As a beginner in learning highchart, I cannot find out why the chart cannot display in the view. My controller displays the json data properly but when I call the controller in the $.getJSON to display the data in the chart I got a blank page.
Can someone help me to make the chart display in the View ?
Thanks
My controller
public function chartBarData()
{
$query1 = $this->model_admin->getBarCha1('2019-01-24','2019-01-25');
$category = array();
$category['name'] = 'Medico';
$series1 = array();
$series1['name'] = 'Paciente';
foreach ($query1 as $row)
{
$category['data'][] = $row->Medico;
$series1['data'][] = $row->Paciente;
}
$result = array();
array_push($result,$category);
array_push($result,$series1);
print json_encode($result, JSON_NUMERIC_CHECK);
}
print json_encode($result, JSON_NUMERIC_CHECK) result :
[{"name":"Medico","data":["baptiste prophete","JUAN ALBERTO SUERO","ADRIANA MATEO","RAUL ARISTY COMAS","VICTORIA LILA FRANCO","IVANHOE LINARES VENTURA"]},{"name":"Paciente","data":[2,3,15,13,1,6]}]

Remove empty space on highcharts column chart left side

I'd like to remove the empty space at the left of the chart.
Have found no solution so far.
OK so i want all the columns to be placed on the right side of the ticks as in the fiddle, and remove the empty space between the y axis and the first tick.
Thanks in advance
$(function() {
Highcharts.chart('container', {
chart: {

Thanks
First of all, define your width / height, secondly you can modify size of chart by parameter:
http://api.highcharts.com/highcharts#plotOptions.pie.size
Try setting minimum width and height of the div container where you are generating chart like this
<div id="pie1" style="min-width: 400px; height: 400px; margin: 0 auto"></div>
Had the same issue when working with mutliple piecharts. Only 1 of the piecharts appeared smaller in size. The reason being max-width was set for the div element. Once I removed the max-width attribute, it worked fine.
<div id = "ab" style="min-width: 310px; height: 400px; max-width: 600px; margin: 0 auto">
to
<div id = "ab" style="min-width: 310px; height: 400px; margin: 0 auto">
