Bug creating bar chart

Hello,

I made a new graphics in the dashboard. It should be relatively simple and in my local it does work as expected.
My code is below:

function display_sales_per_month()
{
    $pg = new graph();

    
    $this_year = date('Y');
    $title = _('Sales per month');
    $data = get_sales_in_year($this_year);
        $months = array(_('Jan'), _('Feb'), _('Mar'),
            _('Apr'), _('May'), _('Jun'),
            _('Jul'), _('Aug'), _('Sep'),
            _('Oct'), _('Nov'), _('Dec'),
        );
        $x_axis = array();
        $y_axis = array();
        foreach($data['monthly'] as $k=>$v){
            $x_axis[] = $months[$k-1];
            $y_axis[] = $v;
        }
        
        $pg->x = $x_axis;
        $pg->y = $y_axis;
    source_graphic($this_year, $title, _(""), $pg, _("Sales per month"), null, 1);
}

It just display total invoice per month.
What I got when I upload is this:
