我正在使用Highchart和Codeigniter。我正在顯示不同月份的項目請求。在Codeigniter中使用Highchart
圖形顯示正常,但x軸值顯示的是numneric值(0,1,2 ...)而不是月份名稱。這是我的控制器代碼:
public function data()
{
$data = $this->project->get_data();
$ab = array();
$category['name'] = 'Category';
$series1 = array();
$series1['name'] = 'WordPress';
$series2 = array();
$series2['name'] = 'Code Igniter';
$series3 = array();
$series3['name'] = 'Highcharts';
foreach ($data as $row)
{
$category['data'][] = $row->month;
$series1['data'][] = $row->wordpress;
$series2['data'][] = $row->codeigniter;
$series3['data'][] = $row->highcharts;
}
$result = array();
$result1 = array();
array_push($result1,$category);
array_push($result,$series1);
array_push($result,$series2);
array_push($result,$series3);
$this->view_data['ctg'] = json_encode($result1, JSON_NUMERIC_CHECK);
$this->view_data['series_data'] = json_encode($result, JSON_NUMERIC_CHECK);
$this->load->view('chart_high', $this->view_data);
}
下面給出在chart_high視圖:

如果我硬編碼類別爲[「一月」,「二月」],則X軸的值是按照我想要的方式顯示爲一月,二月等。
請在這方面幫助我。
由於提前,
它看起來像你應該改變你的系列數據數組。你可以嘗試使你的數據看起來類似於:[[''month1',1],['month2',1]],它應該適用於你的情況。 –
當我使用 打印json_encode($ result1,JSON_NUMERIC_CHECK); 然後輸出爲 [{「name」:Category「,」data「:[」January「,」February「,」March「..」December「]}]。 我只需要捕獲數據部分並放入類別 任何幫助這樣做將不勝感激,因爲我在我的智慧結束。 – John
