Python matplotlib MAXTICKS,matplotlib,python-3.6,Matplotlib,Python 3.6,你好 我在一个包含7个变量和42个数据元素的数据集上得到一个错误“Overses Locator.MAXTICKS”。我让代码在一个不遵循面向对象设计的程序中工作。我正在将应用程序转换为基于GUI的应用程序。我创建了一个类并移动了代码，从那以后，它一直抛出“RuntimeError:Locator试图从729937.416667到733955.541667:Overses Locator.MAXTICKS生成32146个刻度”我在我的Raspberry Pi和我的Ubuntu桌面上都遇到同样的错

你好

我在一个包含7个变量和42个数据元素的数据集上得到一个错误“Overses Locator.MAXTICKS”。我让代码在一个不遵循面向对象设计的程序中工作。我正在将应用程序转换为基于GUI的应用程序。我创建了一个类并移动了代码，从那以后，它一直抛出“RuntimeError:Locator试图从729937.416667到733955.541667:Overses Locator.MAXTICKS生成32146个刻度”我在我的Raspberry Pi和我的Ubuntu桌面上都遇到同样的错误

所附代码包含提取的类和示例数据。欢迎任何评论

我的平台是Ubuntu 17.10、Python 3.6.3和Raspberry Pi（Raspbian）Linux PSensor 4.9.59-v7+#1047 SMP Sun 10月29日12:19:23 GMT 2017 armv7l GNU/Linux、Python 3.5.3

matplotlib在不喜欢接收到的数据时抛出Locator.MAXTICKS错误。我简化了代码，以获取数据结构并将其复制到一个麻木的数组中，它将绘制数据。当我将代码移动到我的GUI应用程序时，它将在第一次显示图形，并在随后的过程中失败。每次都抛出MAXTICKS错误

我从GUI中删除了所有matplotlib代码，并将其替换为pygal中的十行代码，并将图形保存到临时文件中。然后按下按钮显示该文件。每次都有效。越简单越好

如果你想在这里得到帮助，你需要提供帮助。什么是
/home/jcfoller/Desktop/HResImage.jpg
？这是打印图形中预期保存的图像。附加的代码将重现该问题。如果它在另一个系统上工作，那么问题就出在我的Ubuntu和Raspberry Pi设备上。不，你肯定有代码问题，而不是系统问题。但是您应该提供可以在另一个系统上运行的。就目前情况而言，我需要花半个小时才能真正理解绘图应该显示的内容，而问题可以用一行左右的代码来解决。
