Hello, is there any way to plot histogram of whole dataset like following : a|470x349
Yes, of course. What language? Matlab, Octave, and R have histogram routines built in. Python has several libraries – you can choose from Seaborn, Matplotlib, or ggplot2. C, C++, and FORTRAN have libraries as well – see www.netlib.org. I’m certain there are plotting libraries for Javascript, Java, C#, etc (although I don’t have any pointers handy).
Did you try Google?
I am using Python.but I could not find any way to plot whole dataset.
