问题描述

下面是使用plotly.js创建等高线图的示例。某些轮廓线重叠



如何更改阴谋设置以避免(例如增加分辨率,切换轮廓算法)?如果我使用conrec.js绘制相同的数据,轮廓不重叠。



A。 Conrec.js (此操作无重叠)

Below is an example for creating a contour plot with plotly.js. Some of the contour lines overlap.

How can I alter the plotly settings to avoid that (e.g. increase resolution, switch contouring algorithm)? If I plot the same data using conrec.js the contours do not overlap.

A. Conrec.js (this works, no overlap)

Source code for the example: https://github.com/jasondavies/conrec.js/tree/master/example

B. Plotly.js (does not work: overlapping contours)

Source code for the example: https://jsfiddle.net/jwmdw3o1/

  }
  ...
}];
