问题 I am trying to build the d3 chart with the positive and negative number values as below and I found some examples of this and this. I am facing difficulties in customizing it because I have no prior experience in d3 and I think it would need some time for learning. I tried that as well. Created some simple chart examples but could not achieve the above. So I thought of reaching for help. Maybe someone can help with this if they have already done a similar chart or some guidance would be

问题 I am developing a Qt application that, among other things, converts an Excel spreadsheet in a text delimited with tab file. This is done by running a Windows Powershell script. My problem is that the finished() signal from the QProcess is never emitted, although the conversion is done successfully. And yes, I receive stateChanged() signal. Powershell script (ps_excel.ps1) (adapted from this question) param ([string]$ent = $null, [string]$sal = $null) $xlCSV = -4158 #value for tab delimited

问题 I've created a calculator to show repayments over the term of the loan. I've managed to calculate each months payment, interest, remaining loan but I'm trying to output this into a table. The columns will be a fixed number (5) but the rows should dynamically update based on the number of months. I've seen a few similar posts but can't get it to work for my code. Code below and in jsfiddle HTML <div class="mortgageInput"> <form method="POST" name="calc" onclick="validateForm();repayment()

问题 I have a collection view, and each collection view cell will have a table view which will have different data for each collection view cell. The collection view is done using a storyboard and works fine, but I can not seem to get a UITableView to work inside of it. The Collection view code is below and any help is appreciated. Ideally a technique that allows me to use storyboard to customise the tableview cell, and I am using Swift 4. extension StoryboardViewController:

问题 pt=new Date(2019,11,12,8,2,3) console.log(pt.getFullYear()," ",pt.getMonth()); gives result 2019 " " 11 console.log(pt.getFullYear()+" "+pt.getMonth()); gives the result as 2019 11 What is the difference between using, and + in this example? 回答1: console.log(pt.getFullYear()," ",pt.getMonth()); The above example passes three separate arguments to console.log. What it outputs depends on how console.log is implemented. It has changed over time and is little bit different between browsers. When

问题 I am new to gulp and I'm trying to get browser-sync working. It seems to work fine except that the syncronised scroll is not working. Can anyone see what might be wrong with my setup. var gulp = require('gulp'), jade = require('gulp-jade'), uglify = require('gulp-uglify'), gutil = require('gulp-util'), sass = require('gulp-sass'), livereload = require('gulp-livereload'), browserSync = require('browser-sync'); var outputDir = "builds/development"; gulp.task('jade', function() { return gulp.src

问题 Finding the intersection of the Circle and Infinite Cylinder. (all in 3D) • Circle is defined by center, plane in which it lies and radius. • Cylinder is defined by axis and radius. how can i get the intersection of these two? 回答1: WLOG the cylinder has equation X² + Y² = 1 (if not, you can make it so by translation, rotation and scaling). Then the parametric equation of the circle is P = C + U cos t + V sin t where C is the center point and U , V two orthogonal vectors in the circle plane,
