Teechart HTML5/Javascript 标签可自动扩展

Question

在我写信给他们的支持之前，我想问问你们。

我已经购买了teechart javascript版本。它工作正常，但问题是我在系列上使用的标签相互堆叠，它的日期。

我希望他们只显示适合那里的内容，并在缩放时显示更多内容。

这是我的代码

    <script type="text/javascript">
var Chart;
function draw() {
    Chart=new Tee.Chart("graf");
        var input0 = new Tee.Line();
    Chart.addSeries(input0);
    input0.data.values =  ["-47.9","-47.6","-47.4","-48.6","-48.2","-49.7","-49.1","-49.2","-48.1","-47.6","-48.3","-48","-49.3","-49.2","-49.7","-49.8","-47.5","-47.2","-49","-47.4","-47.6","-49.4","-48.1","-48.6","-48.4","-48.5","-48.7","-49.1","-48.6","-49.4","-49.7"];

Answer 1

我认为自动避免标签堆叠的代码中有问题，我将对其进行审查并为您的示例代码找到修复程序。您可以使用以下代码手动分隔标签：

Chart.axes.bottom.increment=3;
Chart.axes.bottom.labels.alternate=true;
Chart.draw();

另一种方法是将标签旋转 90 度，但此功能尚未发布，有待改进：

Chart.axes.bottom.labels.rotation=90; // degree
Chart.axes.bottom.labels.padding=50;  // pixels
