screencasts's Issues

Navigation routing with various menu & sub menu links

Just out of curiosity, lets say inside the navbar div you had a simple multi layered navigation menu, as seen in the photo -

If each li link had its own partial html file, how would I be able to adjust the script to implement the routing in the same way it was done initially?

Would I have to target the children of the' 'fragmentID'?

Initializing model using a Global function doesn't seem to work for me?

What is going wrong here ?

<!doctype html>
<html lang="en" data-ng-app>
<head>
    <meta charset="utf-8">
    <title>AngulasJS Demo3</title>
    <script src ="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
    <script>
        function nameController($scope){
            $scope.firstname = 'John';
            $scope.lastname = 'Smith';
        }
    </script>
</head>
<body data-ng-controller = "nameController">

Last Name : <input type = "text" data-ng-model="lastname"></input>

Hi Curran,
How can I create git pages like you, only one repository, services page for each sub-folder?

How to run gh-pages from forked screencasts

Hi Curran,
I forked your repo and made some more comments on examples for my own learning, and I want to see examples from gh-pages as you did in the videos. However, when I run https://embracelife.github.io/screencasts/splittingCharts/examples/viewer/#/17 in FireFox browser, I can see everything except the graph and instead there is error 301 Moved Permanently.

What should I do to get it right?

Thanks!
Kenny

stacked bar chart

Hey Curran,

Thanks for the sreencasts, I was very helpful.
I made the stacked bar chart and it works ok, if there is no missing data.
In your csv file" religionByCountryTop5.csv" for example Brazil Hindu is marked zero.
In my case the combination of Brazil Hindu would not be in the file.
How can adjust the code to work if data is missing, I plug the chart on oracle BI, so I don't know in advance if data is going to be missing.

Thanks,

styling different pages

In your screencast you mentioned that the html files for the navigation wouldn't include head, div and body tags..so how would be able to style these different pages?

Labels not getting displayed

Hi Curran,

I saw your video on introduction to D3, nice work. I used one of your graphs in my project link, found a problem that when the name of the labels are large they are not getting displayed. As I'm new to d3 was unable to fix it, maybe we can break the labels in multiple line while adjusting the width of bars or can increase the width of labels section and reduce the size of scale but even then we would have an max width for labels.

Update Youtube Link!

Factory Undefined

Hi,

I was going through all of your tutorial and it is best and easy to understand, i am having one query on example 40 when i am passing $scope as a dependency then why countries is coming as undefined

example code below:
countryApp.controller('CountryListCtrl', ['$scope', function ($scope, countries){
countries.list(function(countries) {
$scope.countries = countries;
});

      console.log(countries);
  }]); 

Please help me understand.

Thanks,
Pradeep

The SPA navigation file keeps finding an errors when trying with a bootstrap navbar.

The Single Page App navigation (I am using the jQuery one) always causes errors when Bootstrap is added. The page never appears when clicked, but the URL changes. However if I refresh, then the page does appear. What am I doing wrong?

I keep getting an error on in Navigation.js at line 42 for me - PageName = link.attr("[href]").substr(1);
(Uncaught TypeError: Cannot read property 'substr' of undefined)
