I have C++ App which wich plot 3 plot
- amplituede vs sample
- amplitude vs frequncey(used FFT for calculation)
- amplitude(in dB) vs frequncey
I want plot 2 with y axis lable represent in DB, without chaning the y value of the plot. That is the plot shape will stay same but the y axis lable need to convert to dB. Is this possible, or is it the right way to represent the data like that.
The plot 3 is actually used the same data of plot 2, but the y value convert to DB. What I want is the plot 2 with y axis lable changed to dB.
