Hello,

We have tested it and we see all borders opening the DOCX with MS Word 2007, MS Word 2010, MS Word 2013, MS Word 2016 and LibreOffice 5 (https://s1.postimg.org/5d3tcr2q67/chart_borders.jpg).

What program and version are you using to open the DOCX? Maybe you can do a break line after each chart to add a line to separate each chart.

This is the code we have run, please check and test it:

<?php

require_once 'classes/CreateDocx.inc';

$docx = new CreateDocx();

$data = array(
    'legend' => array('Legend 1', 'Legend 2', 'Legend 3'),
    'data 1' => array(9, 7, 5),
    'data 2' => array(2, 6, 3),
    'data 3' => array(5, 3, 7)
);
$paramsChart = array(
    'data' => $data,
    'type' => 'barChart',
    'color' => '5',
    'title' => 'my title',
    'sizeX' => '17',
    'legendPos' => 'none',
    'border' => '1',
    'vgrid' => 0,
    'hgrid' => 1,
    'scalingMin' => '0.0',
    'scalingMax' => '10',
    'majorUnit' => 1.0,
    'minorUnit' => 0.0,
    'showValue' => true,
    'chartAlign' => 'left',
    'showTable' => false,
    'font' => "Arial",
    'groupBar' => 'clustered',
);
$docx->addChart($paramsChart);

$data = array(
    'legend' => array('Legend 1', 'Legend 2', 'Legend 3'),
    'data 1' => array(7, 5, 8),
    'data 2' => array(3, 1, 4),
    'data 3' => array(3, 3, 5)
);
$paramsChart = array(
    'data' => $data,
    'type' => 'barChart',
    'color' => '5',
    'title' => 'my title',
    'sizeX' => '17',
    'legendPos' => 'none',
    'border' => '1',
    'vgrid' => 0,
    'hgrid' => 1,
    'scalingMin' => '0.0',
    'scalingMax' => '10',
    'majorUnit' => 1.0,
    'minorUnit' => 0.0,
    'showValue' => true,
    'chartAlign' => 'left',
    'showTable' => false,
    'font' => "Arial",
    'groupBar' => 'clustered',
);
$docx->addChart($paramsChart);

$docx->createDocx('output');

Regards.
