Quickchart package not found

Hi,

I use CI4 on WAMP and PHP 7.3.5.
I've installed ianw/quickchart package to create PNG chart and put it in a html page. Next I convert it in PDF with dompdf.
In a model I wrote

PHP Code:

use Ianw/Quickchart; 


When I use :

PHP Code:

$qc = new QuickChart(array(
          'width'=> 600,
          'height'=> 300,
        )); 


An error appear : Class 'Ianw/Quickchart' not found
I don't know why.
Can you help me ?

The problem might be from the namespace. You need to answer some questions:

- How did you install the package? Composer or manually?
- Where exactly is the package located?

Check the file for the correct namespace to use.

Must be a name space issue, where did you install the package at (directory structure)?

What did you Try? What did you Get? What did you Expect?

I've installed it with composer.
It's located in \vendor\ianw\quickchart

Code below works. You do not add row "use Ianw/Quickchart;"

PHP Code:

$qc = new \QuickChart([
   'width'=> 500,
   'height'=> 300,
 ]); 


See https://packagist.org/packages/ianw/quickchart

It is not namespaced. \QuickChart is correct.
