This is:

- [ x] a bug report
- [ ] a feature request
- [ ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

Output styling should be the same format as the input

What is the current behavior?

Styling is not preserved

What are the steps to reproduce?

ChartInput.xlsx

ChartOutput.xlsx

<?php

require __DIR__ . '/vendor/autoload.php';

$reader = IOFactory::createReader('Xlsx');
$reader->setIncludeCharts(true);
$spreadsheet = $reader->load('ChartInput.xlsx');

$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');    

$writer->setIncludeCharts(true);
$writer->save('ChartOutput.xlsx');

?>

not fixed try to run code from 1st message saved file looks different

@kozhevnikovpe It makes things a lot easier if you describe the differences you see rather than just "saved file looks different". It also helps if you open new issues (possibly cross-referencing the closed issue in your description) rather than keep adding to an issue that was closed 8 months ago.

The sample file 32readwriteLineChart5 was added for the PR which addressed this issue. They are very close, but I agree that there are still some discrepancies.

• The input chart has a border.
• In the input chart, there is no vertical line next to the vertical axis.
• The font sizes on the axis labels and the data points differ.

Can you please open separate issues for each of these, and any other discrepancies that you see. I think I am pretty close to a solution for the first two. The third may require a lot more effort.
