Re: Graphing a D function : possible?

I know that there are graphing calculators already, but these
don't support low level black magic like int <-> float
conversions and i'm lost because there is no way to know if the
code i write is correct without a graph or trial and error,
hence the question.
Many thanks
I'm not that familiar with D libraries, but I'm sure there is a
graphing library. If not, I will make one soon because I need
one. If you just need a graph, write a loop calling that function
and print input, output to a file (csv) Then put it in google
sheets or excel and make a graph.
However, what *I* would do to determine if the function is
correct is look at the output in the console then write unit
tests.

Probably the easiest way would be to run the function on a bunch
of different inputs, and plot the input-output pairs as 2D or 3D
points. Pretty much any plotting software should be able to
handle a list of points.

Re: Is there a graphing library for D?
I know I am too late, as you know best thing always delay. So visit KoolChart to find best chart library.
Is there a graphing library for D?
I'm looking for a graphing library for D. Preferrably, something that uses Qt, but it doesn't have to. I am plotting sonar data, and I need to plot it 'live' so... I need something that is: 1. simple to use. I just want to graph x,y data. 2. ability to scale the display. 3. displaying more than one curve on the same graph. 4. Allows for animation of data. So, suppose I graph curve 1. Now I tell the library, okay data for curve 1 has been changed, please refresh graph. In this manner, I can move an object, and see the reflection in 'real time'. Real time in my case would be 10-30ms. Does such a library exist? I click the library section on this site, and nothing stood out. thanks.
