I wonder how I could change the tooltips for the Matplotlib toolbar buttons (I need to translate the English descriptions since my application is in Czech language). I'd also like to change/translate or just remove the descriptions ( pan/zoom , zoom rect ) that appear next to the toolbar panel when clicking on the zoom or pan button. I found some useful tips concerning how to add or remove buttons from the toolbar, but haven't found any advice for

The closer I got was till : DF2= DF1.groupby(by=['C']).max() where I land up getting max of both the columns , how do i do more than one operation while grouping by. 回答1: try agg() function: import numpy as np import pandas as pd df = pd.DataFrame(np.random.randint(0,5,size=(20, 3)), columns=list('ABC')) print(df) print(df.groupby('C').agg({'A': max, 'B':min})) Output: A B C 0 2 3 0 1 2 2 1 2 4 0 1 3 0 1 4 4 3 3 2 5 0 4 3 6 2 4 2

计算机网络从交换技术、使用对象、传输介质、覆盖范围和拓扑结构五个方面进行分类。 按覆盖范围可分为：广域网（WAN）、城域网（MAN）、局域网（LAN）、个域网（PAN）。 按拓扑结构可分为：总线型网络、星型网络、环型网络、网状型网络。 按交换技术可分为：电路交换网络、报文交换网络、分组交换网络。 按使用对象可分为：公用网络、专用网络。 按传输介质可分为：有线网络、无线网络。 来源：博客园 作者： 码农默默 链接：https://www.cnblogs.com/Wendows/p/11667776.html

I'm working with D3 and so far I've been able to tweak the chloropleth example to only draw a specific state. This involved simply removing all the other polygon data so that I'm left with the state I need. I started with this: and then tweaked things to this: However, what I'd like to do is to auto pan/zoom the map upon creation so that the state is front and center on the display, like this: Do I do this through the D3 library? or some independent code (I currently have jquery-svgpan running with d3 to allow for manual panning/zooming) in order to make this happen? The easiest way to

这两天在工作中遇到了许多bug，有一些没来得及总结。今天总结一下使用addEventListener监听事件出现的问题 项目是用vue来做的，首先在mounted函数里面使用：window.addEventListener('scroll', this.pageScroll); 然后就是pageScroll()方法的一顿操作，最常用到的就是获取页面滚动距离 let top=document.documentElement.scrollTop||document.body.scrollTop; 然后在各种操作之下就出现了： Unable to preventDefault inside passive event listener due to target being treated as passive. See < 这样的报错。 上网找了解决方法，大部分的解决方案都是以下两种： window.addEventListener('touchmove', func, { passive: false }) * { touch-action:none; } 第一种方法passive在移动端滑动处理默认值为true，浏览器忽略preventDefault() 第二种方法touch-action是css中的一个属性，用于设置触摸屏用户如何操纵元素的区域（例如浏览器内置的缩放功能）

I have an activity with LinearLayout as its main Layout. In that layout, there is a button that adds a View (R.layout.motor_block) to the main layout (R.id.layout): LayoutInflater inflater = (LayoutInflater)this.getSystemService( Context.LAYOUT_INFLATER_SERVICE ); View iv = inflater.inflate( R.layout.motor_block, null ); RelativeLayout rl = (RelativeLayout) findViewById(R.id.layout); rl.addView(iv); This works fine, but when I add more Views, the screen gets filled up with them so I need a way to "extend" the size by adding pan so I can go through all the views. I also want to add zoom. I

【题解】Informacije [COCI2012] 传送门： 官方题面 【题目描述】 有一个长度为 \(n\) 的 序列 \(a\) （由 \([1,n]\) 中的数组成，且每个数只会出现一次），现给出两个整数 \(n,m\) 和 \(m\) 个关于 \(a\) 的描述，格式如下： \(1\ l\ r\ v\) 表示 \(max\{a[l],a[l+1]...a[r]\}=v\) , \(2\ l\ r\ v\) 表示 \(min\{a[l],a[l+1]...a[r]\}=v\) 。 请输出一个满足上面 \(m\) 个描述的序列，如果多种答案，输出任意一种，无解则输出 \(-1\) 。 【样例】 样例输入： 3 2 1 1 1 1 2 2 2 2 样例输出： 1 2 3 样例输入： 4 2 1 1 1 1 2 3 4 1 样例输出： -1 样例输入： 5 2 1 2 3 3 2 4 5 4 样例输出： 1 2 3 4 5 【数据范围】 \(100 \%:\) \(1 \leqslant n \leqslant 200,\) \(0 \leqslant m \leqslant 40000\) 【分析】 \(n \leqslant 200\) ，一开始只是觉得可以写 \(n^3\) 的算法，比如矩阵乘法之类的，但看到 \(m \leqslant 40000\) 时

For the Tinder app in iOS, I assume they are using a pan gesture recognizer on the image view. How is it that another image is shown underneath the image the user has started to move? Do they have another image view and after the gesture recognizer finishes, dynamically set the image view gesture recognizer, and finally create another image view underneath? https://github.com/cwRichardKim/TinderSimpleSwipeCards Take a look at this. It kind of breaks down what goes into making swipe cards. The answer to your question is that there is an array of cards, with only 2 or 3 on the view controller at
