Question

在构建自定义样式并将其保存在“.mplstyle”文件夹中之后，我将此mplstyle导入到新脚本中。不幸的是我遇到了一些错误。

我怀疑这与我如何格式化“.mplstyle”文件有关，但我不太确定。如果您需要有关我的计算机或我正在运行的脚本的更多信息，请告诉我。

修改

这是我使用的代码

# Example of Use
import matplotlib.pyplot as plt
#plt.style.use("codepan.mplstyle")
plt.style.use('ggplot')

n = 50
raw_data = np.random.randn(n)*10

plt.plot(raw_data)
plt.show()

这是mplstyle文件的片段

lines.dashdot_pattern : [6.4, 1.6, 1.0, 1.6]
lines.dashed_pattern : [3.7, 1.6]
lines.dotted_pattern : [1.0, 1.65]

Answer 1

您想要从这些行中删除方括号

即。他们应该看起来像：

lines.dashdot_pattern : 6.4, 1.6, 1.0, 1.6
lines.dashed_pattern : 3.7, 1.6
lines.dotted_pattern : 1.0, 1.65

例如，请参阅classic.mplstyle示例表中的here。

自定义样式maplotlib（.mplstyle）
