Parallel Coordinates Plot: Axis Types

The underlying plotly.js parcoords doesn't support log projection (scales, axes) at the moment, though as you mention it comes up sometimes and we plan with this functionality. In the meantime, an option is to take the logarithm of the data ahead of time, with the big drawback that axis ticks will show log values, which needs explanation and adds to cognitive burden.

For an illustration of the issue please have a look at the corresponding stack-overflow question.

首先阅读底层的 plotly.js parcoords 实现，以及关于所报告轴行为的链接 Stack Overflow 问题。确定当前如何处理轴的比例和刻度，然后定义对数投影和轴类型应支持的内容，再为最终的轴显示添加覆盖测试。
