i work on asp.net mvc3 project , and i have to display histogram in view depending on data coming from action, can you suggest me any library javascript that can be easy to use and make good histogram, please any syggestion !!
http://www.highcharts.com/ - excellent integration and nice looking (free for non-commercial)
http://www.jqplot.com/ - open source, nice looking as well (free as in beer)
http://g.raphaeljs.com/ - another open source, well maintained
http://www.flotcharts.org/ - built specifically for JQuery (if that is what you are using)
Basically, take a look at these and others, find one that looks good and will easily plug in to your existing architecture and roll.
If you just want to sort the data into bins, take a look at histogram.js.

I am currently working on my first small desktop menubar app (macOS, Swift 3). It needs to access
a) A list of words (Think word dictionary, 1k-5k words, per supported language)
b) A list of structured data (Think simple structs, ~500)
I am currently pondering, whether to build these in code - maybe a factory class per language. Or include them in my app as json and parse at runtime. Or maybe build an SQLite file and read that during runtime, although that approach would be harder to diff in source control ...
As I am new to the platform I was wondering whether there might be a better way that I am not aware of, or maybe performance considerations that render one of the mentioned approaches useless.
As usual, thanks in advance folks !
Your listed solutions can be used for this task. However I think for such kind of tasks the best solution is to use CoreData, where you can store a list of words as well as structured data, also make relations between them if you need it
First of, is there any real documentation of the toolkit ? What I would like is to specify a range of selectable dates. For example I don't want to display dates before today. If the user select a start date of Jan. 27th 2012, I want to allow only dates after these for the return date
Documentation is a little bit sparse for the toolkit - your best bet is to look in the source of the sample app but they don't cover all the scenarios.
The default control doesn't seem to support a minimum or maximum value for the selected date, but if you download the source you should be able to modify it according to your needs. The layout of the source is pretty straightforward and you should be able to find an acceptable place to add the code, the only thing you need to decide is how you handle it from a UI perspective. In my opinion, you are better off handling the range check once the control returns - if it is an invalid date, pop up a message and re-show the control.
I've found that in the absence of documentation, the WindowsPhoneGeek blog (in this specific case see link here) usually does a good job of explaining the Silverlight Toolkit components in their various articles.
These articles can be a great help when following ZombieSheep's advice of taking a look at the toolkit sample code.
I would like to use tags like {{headline}} in the CodeIgniter views instead of PHP and I'm looking for a template parser. CodeIgniter has a built-in template parser: http://www.ellislab.com/codeigniter/user-guide/libraries/parser.html
The question is if it's better to use the built-in parser or another parser? Are there any limitations with the CI template parser like not supporting loops, if statements, etc.?
If so, there are a number of other parsers but it seems that a developer works on them for some time and then it falls into a numb state when it's not supported any more. I'm looking for a parser which will also be supported in a year:
Bucket

Comper Template Parser
http://parser.comper.sk/en/
Ocular-Template-Library
http://github.com/lonnieezell/Ocular-Template-Library
Phil Sturgeon Template library
http://philsturgeon.co.uk/code/codeigniter-template
PyroCMS Lex Parser
http://github.com/pyrocms/lex
Template Library for CodeIgniter
http://www.williamsconcepts.com/ci/codeigniter/libraries/template/
The most active seem to be Comper and Lex Parser. What is the difference between Phil Sturgeon Template library and PyroCMS Lex Parser because it's the same developer?
What I am looking for is:
- Separation of PHP and HTML/CSS in views
- Solidly supported so that it's not stalled within a year
- Use of simple tags but also loops, if statements and other functions
Can anyone give me a tip? The existing information on the CI forum or elsewhere have not been really useful.
Many thanks!
Philip
How to Choose a Template Engine
I went through a similar exercise for choosing a PHP/CMS system, and here are some points that may carry over to your decision making process.
I first look at the documentation to get a sense of how much support there is for the system, evaluate range of features and so on. I also see if there is an online forum with enough activity to get some help if needed.
I then try out the installation to see if it goes smoothly. If I have trouble at this stage, I may simply quit and try another system unless there is an online forum or help desk with a ready answer.
I then set up a sample website (2-3 pages) and try out the features that I need. In the case of CodeIgniter, I may have content stored in multiple database tables and I evaluate how much effort it takes to get the data from my SQL queries into the array structure that can be used by the template system. This is usually the step that takes the most effort when developing the website.
I also check to see how easy I could integrate a PHP function into the mix. For example, I once had to build a specialized function to determine a range of dates and these dates had to be passed to the template engine. I was able to do it but it took a lot of effort. The template system had almost no support for parsing dates and I had to resort to a PHP function to do the work.
Summary
Ultimately, you will need to try a few of these systems out to get a feel for them. Once that is done, pick one that makes sense for your coding style, ease of use, and your data structure.
PS
I have not used the systems that you listed above but I have spent quite a bit of time using the template engine in Expression Engine (CMS from the same group that created CodeIgniter). My comments are based on my experience implementing database driven websites using Expression Engine and dealing with the limitations and quirks of that particular platform.
I have been working with CakePHP which has model associations such as hasMany, belongsTom etc...
Now I am working with Joomla and need this type of functionality.
All I need is a point the right direction such as a link describing it as I cannot seem to find something about it on Google.
take care,
lee
There' is a world of difference between the two, and goes far beyond a simple answer on SO. The API Docs are quite extensive, and there are many decent examples. Developing a Model-View-Controller (MVC) Component for Joomla!2.5 will likely also give you some good reference. Additionally, with 9000+ open source extensions available, it's usually quite easy to find one that comes close to what you want to do in order to have some sample code to work from.
I would like to represent data that gives an overview but allows them to drill down in an inline fashion - so if you had a grouping of say 6 objects the user could expand the data and it would show the 6 objects immeadiately below it before any more high level data.
It would appear that MSHFlexgrid gives this ability but I can't find any information about actually using it, or what it's limitations are (can you have differing number of fields and/or can they have different spacing, what about column headers, indentation at for the start, etc).
I found this site, but the images are broken (in ie8 and ff3.5). Google searches show people just using the flat data representation but nothing using the hierarchical properties). Does anyone know any good tutorials or forums with a good discussion about pitfalls?
Due to lack of information about using it, I am thinking of coding my own version but if anyone has done work in this area I haven't found it - I would of thought it would be a natural wish for data representation. If someone has coded a version of this (any language) then I wouldn't mind reading about it - maybe my idea of how to do it wouldn't be the best way.
You might want to check out vbAccelerator. He has a Multi-Column Treeview control that sounds like what you may be looking for. He gives you the source and has some pretty decent samples.
The MSHFlexGrid reference pages and the "using the MSHFlexGrid" topic in the Visual Basic manual?
Sorry if you've already looked at these!
