math - Why are the arguments to atan2 Y,X rather than X,Y? -

-

सी में atan2 फ़ंक्शन में निम्न हस्ताक्षर हैं: 

  डबल एटैन 2 (डबल वाई, डबल एक्स);

अन्य भाषाएं भी ऐसा करते हैं यह एकमात्र ऐसा कार्य है जो मुझे पता है कि वाई, एक्स ऑर्डर के बजाय वाई, एक्स ऑर्डर में अपनी बहस लेती है, और मुझे नियमित रूप से पेंच करते हैं क्योंकि जब मुझे लगता है कि निर्देशांक, मुझे लगता है (एक्स, वाई)।

> क्या किसी को पता है कि क्यों एना 2 का तर्क आदेश सम्मेलन इस तरह से है?

क्योंकि मुझे विश्वास है कि यह आर्कटॅन से संबंधित है (Y / x), इसलिए y शीर्ष पर दिखाई देता है।

यहाँ एक अच्छा लिंक है जो कि इसके बारे में थोड़ा सा है:

delphi - Mouseover hint for TChart series value -

Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
