first of multiple graphs because doing echo inside loop take 1 value , create graph that.

you have create array of values , pass graph widget following

$graph_data = []; $graph_data[] = array('year', 'sales', 'expenses');   for($i = 0, $modem = $modelemployee; $i < sizeof($modelemployee); $i++){  $arr['id'] = $modem[$i]['id'];  $arr['sales'] = $modem[$i]['sales'];  $arr['expenses'] = $modem[$i]['expenses'];  $graph_data[] = array($arr['id'],$arr['sales'],$arr['expenses']); //add values require set in order of year, sales , expenses } //loop ends here echo googlechart::widget(array('visualization' => 'linechart',              'data' => $graph_data,             'options' => array(                 'title' => 'my company performance2',                 'titletextstyle' => array('color' => '#ff0000'),                 'vaxis' => array(                     'title' => 'scott vaxis',                     'gridlines' => array(                         'color' => 'transparent'  //set grid line transparent                     )),                 'haxis' => array('title' => 'scott haixs'),                 'curvetype' => 'function', //smooth curve or not                 'legend' => array('position' => 'bottom'),             )));
