如何在 Embarcadero 的HTML5 Builder(Embarcadero® HTML5 Builder 版本 5.1.167.137)中更改MChart组件系列的颜色?在我的服务器移动应用程序中,我使用下面的代码从数据库中填充带有参数值的图表。我还创建了黄色的下限和上限线以及红色的下限和上限线。我的问题是我无法弄清楚如何更改黄色和红色系列,以便它们实际上是黄色和红色。

创建一个 Server Mobile 应用程序,在表单上放置一个 MChart,在页面 OnShow 事件中,使用以下代码:

function MPage5Show($sender, $params)
{
    // set up y-axis from 0 to 100
    $this->MChart1->Axes->Left->Automatic=false;
    $this->MChart1->Axes->Left->Minimum=0;
    $this->MChart1->Axes->Left->Maximum=100;

    $yellowLoValues = array();
    $yellowHiValues = array();
    $redLoValues = array();
    $redHiValues = array();
    $values = array();
    // yellow low and hi limits
    $ylo=30;
    $yhi=70;
    // red low and hi limits
    $rlo=20;
    $rhi=80;

    for ($i=0;$i<10;$i++)
    {
        // generate random values, " Y, X "
        array_unshift($values, rand(0,100).','.$i);
        $yellowLoValues[] = $ylo;
        $yellowHiValues[] = $yhi;
        $redLoValues[] = $rlo;
        $redHiValues[] = $rhi;
    }
    // MChart1->Data takes array with values as "Y,X"
    $this->MChart1->Data = $values;

    $series1=$this->MChart1->addSeries(new TeeLine($this));
    $series1->ColorEach = ceNo;
    $series1->Values=$yellowLoValues;
    $series1->Title="Yellow Low Limit";

    $series1=$this->MChart1->addSeries(new TeeLine($this));
    $series1->ColorEach = ceNo;
    $series1->Values=$yellowHiValues;
    $series1->Title="Yellow High Limit";

    $series1=$this->MChart1->addSeries(new TeeLine($this));
    $series1->ColorEach = ceNo;
    $series1->Values=$redLoValues;
    $series1->Title="Red Low Limit";

    $series1=$this->MChart1->addSeries(new TeeLine($this));
    $series1->ColorEach = ceNo;
    $series1->Values=$redHiValues;
    $series1->Title="Red High Limit";
}
