Hi all!
I'm on a project which generates a waveform from an audio and plots it in a qwtplot. I have that. The problem is that I dont get the values from milliseconds but from the pcm length. So my audio is 4900 milliseconds long and has over 50000 pcm data to plot then the qwtplot axis label shows the numbers to 50000. Can I divide that numbers on my label with the frequency to get the labels as milliseconds? Is there any easy way? Please explain it to me but not with the cpuplot example cause my plot isn't about that x axis labels.
