javascript - 是否可以在plot.ly 3D散点图上手动设置比例和刻度？

Question

我有一个基本的plot.ly 3D散点图，其中包含在三维空间中指定的各种路径。经过三天的阅读文档后，我仍然没有找到定义轴的刻度间隔的方法。它似乎是根据我的数据自动生成它们，这是我不想要的。实际上，我需要三个轴的比例为 1:1:1，这可能吗？

<style>html, body { height: 100%; }</style>
<div id="myDiv" style="width: 100%; height: 100%"></div>

我不太熟悉javascript的plotly api，这个答案是用python写的。希望它对您的情况也有帮助。

如果我正确理解你的问题，你想设置轴的刻度模式，并且根据你选择的模式，你还想设置刻度；刻度0和dticks；或刻度值。

以下内容摘自:https://plot.ly/python/reference/#layout-scene-xaxis-tickmode一个难以有效搜索但非常有用的页面。该页面的 javascript 版本是:https://plot.ly/javascript/reference/#layout-scene-xaxis-tickmode

tickmode (enumerated: "auto" | "linear" | "array" ) Sets the tick mode for this axis. If "auto", the number of ticks is set via nticks. If "linear", the placement of the ticks is determined by a starting position tick0 and a tick step dtick ("linear" is the default value if tick0 and dtick are provided). If "array", the placement of the ticks is set via tickvals and the tick text is ticktext. ("array" is the default value if tickvals is provided).
