Question

有没有办法在highcharts js图表中添加网格线但在现有线之间没有标签？

我已经拥有值为1,2,3等的网格线，我会添加0.5,1.5,2.5等行，但轴上没有标签。

另外，我需要计算间隔（每次可能不同的步骤之间的中间点）。

Answer 1

您可以启用次要刻度并将其if (count($_FILES['field2']['name']) >= 1) { //Loop through each file for ($i = 0; $i < count($_FILES['field2']['name']); $i++) { //Get the temp file path $tmpFilePath = $_FILES['field2']['tmp_name'][$i]; //Make sure we have a filepath if ($tmpFilePath != "") { //save the filename $shortname = $_FILES['field2']['name'][$i]; //save the url and the file $filePath = "uploads/" . date('d-m-Y-H-i-s') . '-' . $_FILES['field2']['name'][$i]; $filePath1 = "uploads/" . date('d-m-Y-H-i-s') . '-' . $_FILES['field2']['name'][$i]; //Upload the file into the temp dir if (move_uploaded_file($tmpFilePath, $filePath)) { $sql = "INSERT INTO " . $config_tbl_prefix . " subcontractor_qs (field1, field2) VALUES ('$filePath','$filePath1')"; mysql_query($sql); } } } } }设置为0.5。

    plotLines: [{
      color: '#ccc',
      width: 1,
      value: 0.5 //position where line needed
    }, {
