The basic use of fit is best explained by a simple example: f(x) = a + b*x + c*x**2 fit [-234:320][0:200] f(x) ’measured.dat’ using 1:2 skip 4 via a,b,c plot ’measured.dat’ u 1:2, f(x) Ranges may be specified to filter the data used in fitting. Out-of-range data points are ignored. (T. W...

Try catch Errors must always be handled. If you are using synchronous programming you could use a try catch. But this does not work if you work asynchronous! Example: try { setTimeout(function() { throw new Error("I'm an uncaught error and will stop the server!"); }, 1...
