Hello everyone,
I have an issue with a uni project. During the code, I make a plot canvas that works perfectly, showing a Fourier transformed graph with the frequencies, but then have to ask the user which frequencies he wants to cut away. This implies using a std::cin AFTER having launched the two Canvas, so when I execute the program this canvas is completely white until i do not cin these numbers. The problem is that those numbers depends on the plot (I have to see it!) How can I do?
The code is something like this:
[previous code]
float low_freq = 0;
float top_freq = 0;
std::cout << “Which range of frequencies would you like to cut?” << std::endl;
std::cout << "From (Hz): ";
std::cin >> low_freq; //THIS STOPS THE EXECUTION! WHITE CANVAS
std::cout << "To (Hz): ";
std::cin >> top_freq;
std::cout << std::endl;
[rest of the code]
The quesiton is: how can I make the plot be seen before typing input data? Because those frequency have nothing to do with the plot…
Thanks in advance!
