loess line not plotting correctly

烈酒焚心 提交于 2019-12-19 08:11:20
问题 I'm having trouble fitting a loess smooth plus confidence limits to a scatterplot of residuals. My model is height ~ weight + chest circumference. To check linearity of chest circumference, I've fitted a model without chest circumference (i.e. height ~ weight), and plotted the residuals of this model against chest circumference. So far so good. I then tried to use loess() and predict() to plot a loess line, plus confidence limits. The result looks like this (in the picture I've only plotted

C++ getline函数用法

▼魔方 西西 提交于 2019-12-19 07:04:06
getline()函数是一个比较常见的函数。根据名字直接望文生义,就知道这个函数是来完成读入一行数据。 下面就对C++ -- getline()函数的用法说明,以及getline()函数作为while条件的问题,总结一下: 在C++中本质上有两种getline函数: 第一种:在头文件<istream>中,是iostream类的成员函数。 第二种:在头文件<string>中,是普通函数。 /////////////////////////////////////////////////////////////////////////////////////////// 第一种: 在<istream>中的getline()函数有两种重载形式: istream& getline (char* s, streamsize n ); istream& getline (char* s, streamsize n, char delim ); 作用是: 从istream中读取至多n个字符(包含结束标记符)保存在s对应的数组中。即使还没读够n个字符, 如果遇到delim 或 字数达到限制,则读取终止,delim都不会被保存进s对应的数组中。 *例程代码: #include "stdafx.h" #include <iostream> //使用标准输入流和标准输出流。 // std::cin ;

Is there any way to draw lines with subpixel precision in Swing?

问题 This question has been asked before, but the answers don't solve the problem, so I ask it again. It was suggested that instead of using g2.drawLine , you could use g2.draw(line) , where line is a Line2D.Double . However, as you can see from the screenshot, the lines are still drawn as if they ended on an integer pixel (each set of 10 lines is exactly parallel). import javax.swing.*; import java.awt.*; import java.awt.geom.Line2D; public class FrameTestBase extends JFrame { public static void

Drawing lines with GLSL

我只是一个虾纸丫 提交于 2019-12-19 04:57:14
问题 is it possible to draw a line with GLSL using GL_TRIANGLES? The reason why i ask is i'm trying to draw a line with adobes molehill and it only draws triangle. Cheers 回答1: if you set edge rendering to be on, just draw a triangle with point 1 and 3 at the same position. It's not efficient, but it works. 回答2: If you can, use a geometry shader. Pass in two vertices and a line width, generate 4 points forming two triangles by shifting the vertices, render and be done... But drawing wide lines

Matlab: I have two points in a 3D plot and i want to connect them with a line

问题 I have a 3D plot and two points coordinates A(0,0,0) and B(13,-11,19). I just want to plot a visible line connecting this two points ... I tried plot3(0,0,0, 13,-11,19) and other stuff but everything i tried failed miserably. 回答1: Here's how: % Your two points P1 = [0,0,0]; P2 = [13,-11,19]; % Their vertial concatenation is what you want pts = [P1; P2]; % Because that's what line() wants to see line(pts(:,1), pts(:,2), pts(:,3)) % Alternatively, you could use plot3: plot3(pts(:,1), pts(:,2),

Parse comment line

十年热恋 提交于 2019-12-18 21:18:22
问题 Given the following basic grammar I want to understand how I can handle comment lines. Missing is the handling of the <CR><LF> which usually terminates the comment line - the only exception is a last comment line before the EOF, e. g.: # comment abcd := 12 ; # comment eof without <CR><LF> grammar CommentLine1a; //========================================================== // Options //========================================================== //=================================================

问题 I have two points having lolLat as 0,10 and 30,0 Now to draw a marker at this point i use this transform while generating marker for it lonLat.transform( new OpenLayers.Projection("EPSG:4326"), // transform from WGS 1984 map.getProjectionObject() // to Spherical Mercator Projection ) How can i draw line between them is there any way to do that in openlayers,i have tried doing it with linestring in vector layer but it doesn't seems to be working for me. 回答1: For example: map = new OpenLayers
