如何使用sizer例程在不同的面板上找到支持多个标绘比例和Xaxis的代码？

Question

我一直在使用这个代码作为一个模型来修改一个应用程序，以支持在同一个轴上覆盖超过8个单独的绘图，并在两侧使用不同的比例。你知道吗

到目前为止我有几个问题。你知道吗

1. 一些Y标签在左边，一些在右边。2或3在两侧（不是全部）重复（错误）。它似乎是在右侧，覆盖了一个重复造成胡言乱语。一个比例尺包含绘制的数据数量。

2. 当应用程序停止时，黑色窗口（DOS提示窗口）不会消失。我有一个理论，创建了两个“canvas”块，一个是通过调用创建一个实例，使用一个调用创建一个canvas，另一个是创建一个绘图区域（不称之为canvas）。电话如下：

第1组

myLOG_Fig = m_plt.figure(figsize=(3.0, 3.0), dpi=100)
self.myLOG_PlotCanvas = FigCanvas( panel, -1, myLOG_Fig )

设置2

self.myLOG_HostAxes = host_subplot(111, axes_class=AA.Axes)

集合1需要将self.myLOG_PlotCanvas呈现给Sizer放置例程，该例程将图像（绘图区域画布）应用于面板（四个面板之一）。这套作品的伟大，直到我开始其他绘图（2至8）的画布。你知道吗

我找到了一个解决方案（第2组），它使用mpl工具包和AA来共享X轴，并呈现2个以上的比例。通过更改代码以允许设置2，我注意到了问题所在。绘图的比例和颜色正确。侧刻度看起来几乎不错（例外是在右边重复），我不能改变X轴标签和Y轴标签的字体大小。我可以用set 1控制颜色和字体大小。集合2对更改角色属性没有响应。还有一些代码必须使用集合2所需的代码（但我没有在这里列出）。我个人不认为这两个画布绘图区域是相同的，这也是为什么应用程序没有死掉的原因之一（黑色DOS窗口徘徊）。你知道吗

是否有更新版本的matplotlib和mpl\u工具包代码将例程连接到一个画布绘图区域？是否有一些代码可以满足我的要求（使用大小调整器等）来生成一个在每个选项卡上都有选项卡和绘图区域的应用程序？你知道吗

Answer 1

以下是我对问题的解决方案（我在2013年发布）。在寻找答案和解决方案之后，我找到了几个代码片段，并将它们拼凑在一起，使它们成为一个“团队”。。。 省略一些设置代码以保持列出的代码简短。每个的数组 y轴是省略的部分之一。你知道吗

选择一个包含4到7列数据的文件。每一列都呈现给一个数组[]（每个数组都有不同的名称）。将保留插入数组的项目的确切数目的计数。一个数组\u count[]将匹配数据数组中的每个条目。并将指示每个x轴步长的时间步长（本例中为0.0167）。图显示的一个例子已经上传给那些感兴趣的人。你知道吗
