Re: [Matplotlib-users] Plotting multiline graph with large dataset (6 lines, about 30, 000, 000 points total

Hello Krishna, This is really crazy ploting so many data point, after all the human eye can't separate all the data. Try sampling the vector of the data point - to a smaller extent. Here's a quick and dirty solution how to sample every nth element in a vector - there's probably a faster way,
