normal bars positioning on d3.js bar chart -


I try to create a chart based on the 2D data array (I initially want to use the 2D array, hence there is a function "merging AR" using D.JS, which merges them is). Here's the code: 

  .bar {fill: steelblue; } .bar: hover {fill: brown; } Var arr1 = [399200,100000, 352108, 600150, 39000, 17005, 4278]; Var arr2 = [839, 14 9, 146, 200, 200, 121, 63]; Function merge AR (array 1, array 2) {var i, out = []; / Literal new array {out.push ([array1 [i], array2 [i]]) for // (i = 0; i & lt; array1.length; i ++); } Exit; } Var data = Merge AR (arr1, arr2); Margin = {top: 20, right: 20, bottom: 30, on the left: 40}, width = 960 - margin. Left - margin. Right, height = 500 - margin.Top - margin.bottom; Var x = d3.scale.linear () .domain ([0, d3.max (data, function (d) {return d [0];})) .ange ([0, width]); Var y = d3.scale.linear () .domain ([0, d3.max (data, function (d) {return d [1];})) .ange ([height, 0]); Var xAxis = d3.svg.axis () .scale (x) .orient ("bottom"); Var yAxis = d3.svg.axis () .scale (y) .orient ("left"); Var svg = d3.select ("body"). Attached ("svg") .attr ("width", width + margin.left + margin.right) .attr ("height", height + margin.top + margin below). Append ("g") .attr ("conversion", "translation (" + margin. Left + "," + margin.Top + ")"); Svg.append ("g") .attr ("class", "x axis") .attr ("transform", "translate (0," + height + ")"). Call (xAxis); Svg.append ("g") .attr ("class", "y axis") .color (yAxis) .append ("text") .attr ("transform", "rotate (-90)") .attr ( "Y", 6) .attr ("dy", ".71em") Style ("text-anchor", "end") svg.selectAll (". Bar"). Data (data) Center () ("square", "bar") .attr ("x", function (d) {returns x (d [0]);} // //.attr("width ", x .rrangeband ( ) .attr ("width", width / a1.length) .attr ("y", function (d) {return y (d [1]);}) .attr ("height", function (d) { Height Height - y (D [1]););

The problem is that the bars are separated from each other, there is no distance between them, even if I have used the range band.

There are 2 problems with your code

The first one is that data array To sort it, you can do this: 

  outside = out.support (function (a, b) {return d3ccending (a [0], b [0])})

Before returning outside to your mergeAt function. Sorting arrays ensures that you do process repeatedly in the correct order

The second issue is that your intervals are not the same, for remedieting for this, I have a Block width (but you want to separate something): 

  .attr ("width", function (D, i) {if (i! = (Data.length-1) ) {Return x (data [i + 1] [0]) - x (data [i] [0])} and {return 10; / / last block width is 10. To find out that at the end of ARI, A // is a cleaner way to add a marker, // how to complete the axis}})

JSField:

edit

To keep the same interval between each time and one width, you have to change the scale to an ordinal: 

  var x = d3.scale.ordinal () .rangeRoundBands ([0, width], .1) .domain (data.map (function (d) {return d [0]}))

Again, the way you count the width You need this to change it: 

  .attr ("Width", x.rangeBand ())

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
