intervals

I'm currently using the charting within .NET using System.Windows.Forms.DataVisualization.Charting.Chart . Thus far it seems very powerful, and works great. However, there is a huge problem in terms of how it is auto-calculating intervals. I use a lot of double values, and in libraries like ZedGraph, it handles this perfectly. It selects min/max/interval just fine. However, in MS Chart, it may select 206.3334539832 as a minimum, and intervals of a similar decimal precision. Obviously this looks quite ugly. So, I tried simply making the axis format {0.00} and it works great when it loads the

A library and webservice I am using communicates time-intervals in ISO 8601 format: PnYnMnDTnHnMnS . I want to convert such formats to seconds. And vice versa. Seconds are a lot easier to calculate with. Example interval values are: PT1M or PT60S (1 minute) PT1H, PT60M or PT3600S (1 hour) I need two functions: parse from such values to seconds: iso8601_interval_to_seconds() and from seconds into such intervals: iso8601_interval_from_seconds() . The latter is rather simple, because it could be done as `"PT{$seconds}S", just pass seconds along, at all times. Maybe this can be done nicer with a

Let's say I have a function: myFunc = function(number) { console.log("Booyah! "+number); } And I want it to run on a set interval. Sounds like I should use setInterval , huh! But what if I want to run multiple intervals of the same function, all starting at the exact same time? setInterval(function(){ myFunc(1); }, 500); setInterval(function(){ myFunc(2); }, 1000); setInterval(function(){ myFunc(3); }, 2000); So that the first runs exactly twice in the time it takes the second to run once, and the same between the second and third. How do you make sure that they all start at the same time so

I want to call an arbitrary function every n seconds. Basically I want something identical to SetInterval from Javascript. How can I achieve this in Scala? You could use standard stuff from java.util.concurrent : import java.util.concurrent._ val ex = new ScheduledThreadPoolExecutor(1) val task = new Runnable { def run() = println("Beep!") } val f = ex.scheduleAtFixedRate(task, 1, 1, TimeUnit.SECONDS) f.cancel(false) Or java.util.Timer : val t = new java.util.Timer() val task = new java.util.TimerTask { def run() = println("Beep!") } t.schedule(task, 1000L, 1000L) task.cancel() If you happen

how to call a method after a time interval? e.g if want to print a statement on screen after 2 second, what is its procedure? System.out.println("Printing statement after every 2 seconds"); The answer is using the javax.swing.Timer and java.util.Timer together: private static javax.swing.Timer t; public static void main(String[] args) { t = null; t = new Timer(2000,new ActionListener() { @Override public void actionPerformed(ActionEvent e) { System.out.println("Printing statement after every 2 seconds"); //t.stop(); // if you want only one print uncomment this line } }); java.util.Timer tt =
