Python读取TXT文件绘制折线图并计算 上一节我们对time_cal.txt文件读取并在一张图上绘制折线图,那么如何分别绘制线形图呢? PS:这里用到的是matplotlib库,详细的函数介绍可以参考:https://matplotlib.org/api/index.html 其实也很简单,话不多说,代码如下 from matplotlib import pyplot as plt import numpy as np fig = plt.figure(figsize=(2000, 100)) # 创建绘图窗口,并设置窗口大小 # 画第一张图 ax1 = fig.add_subplot(511) # 将画面分割为5行1列选第一个 ax1.plot(step, imageresize, 'red', label='imager-esize') # 画imageresize的值,颜色红 ax1.legend(loc='upper right') # 绘制图例,plot()中的label值 ax1.set_xlabel('x') # 设置X轴名称 ax1.set_ylabel('load image-resize') # 设置Y轴名称 画第二张图 ax2 = fig.add_subplot(512) # 将画面分割为5行1列选第二个 ax2.plot(step, data,

QT之控件叠加显示

在项目中经常碰到这种情况,比如UI上的同一个区域既要显示图片又要显示文字时,但是一个label只能显示其中一个,这个时候就需要两个label叠加显示了,比如下面一个显示图片,上面一个显示文字。本文以label叠加显示为例,详细介绍一下控件叠加的方法: 1. 新建一个带ui的工程,在ui上拖上一个QFrame控件,再往QFrame控件中拖放一个QLabel控件,右键设置QFrame控件的布局为水平布局,如图所示: 接着修改布局的属性,如图所示: 点击保存,回到工程所在文件路径,右键记事本打开mainwindow.ui文件 找到QFrame,将其手动修改为QLabel 修改前: 修改后: 点击保存,打开Qt,会提示你文件已改变,直接 Yes and All 即可,改变后的ui如下,重点看圈住的部分,可以看到已经有了两个Label并且时叠加显示的,修改一下stylesheet让其显示的更直观 修改后: 这样就可以了,其他控件方法类似 来源: CSDN 作者: _YunKe 链接: https://blog.csdn.net/qq_39295354/article/details/104010241

Using tkinter to produce n labels where n is variable

安稳与你 提交于 2020-01-16 17:35:37
问题 I'm looking to implement a top level window which has a controllable number of label widgets on it. In my first window, there is a scale widget which you can use to select the number of labels on the top level. These labels then need to be updated in real time. I have code for generating the top level window, as well as for dynamically updating one label on it using the After utility. I can't figure out how to produce a variable set of labels which I can then update later in the code. My

问题 I have the following problem. I use a form when I provide only PIN. I have validator which checks if its a 4-digit number. Then the action on submit is set to the method which checks if the PIN exists in the database. If not it does message = "no PIN"; I used the message in the output label below the form. Previously it was null so there was no message there. Now it changes into "no PIN" but I have to clear it after clicking the submit button again because the error message doesn't disappear

JavaScript入门学习之四——JQuery入门

旧时模样 提交于 2020-01-16 14:26:51
在前面一章我们已经点到过,很多的情况我们都是通过JQuery来对标签进行操作的,在这一章我们就来好好讲一讲这个JQuery。 JQuery初识 先看看JQuery的使用 JQuery的特点: 可以用及其简练的语言来做JS做的事情(write less,do more) JQuery就是一个JS文件,相当于一个Python的第三方模块,直接拿过来用就可以了(但是需要按照要求的规则)。但是原生的JS DOM是基础,其实还是通过这些基础来实现所有的操作。 我们要学习的,JQuery最常用的方向,也就是改变标签的属性、样式和事件相关的一系列操作。 JQuery的基础语法 JQuery的语法还是比较简单的,只有一句必须要掌握的 $(selector).action() 前面的selector就相当于一个标签选择器,后面的action就是相对应的操作 标签选择器 id选择器 $("#id") 标签选择器 $("tagName") class选择器 $(".className") 所有元素选择器 $("*") 选择器的配合使用 $("tagName.className") //两个条件一定不能加空格,要紧挨着,加了空格就有层级的效果,下面会讲到 组合选择器 同时符合多个条件 $("condition1,condition2...") 练习题 结合上面的各种基本组合器看看下面的方法应该怎么实现
