Hello. I have more than one phi-psi time series data files each having 50000 time points. I am trying to create density plots (2d histograms) for each and then I would like to compare them. But to be able to compare one plot with the other I need to have similar colour densities (i.e colour gradient (which depends on counts) will be same for each). But I am unable to control the colour gradient and thus unable to compare the plots.
I was using ggplot2 library. After getting the phi-psi data into R I was doing the following steps: *df <- data.frame(phi[,2],psi[,2])* *p <- ggplot(df,aes(phi[,2],psi[,2]),ymin=c(-180,180),xmin=c(-180,180))* *p + stat_bin2d(bins=100)* after executing these steps I am getting the density plot with the colour gradient legend at the left side with a certain range (say 0-200). I want to control this colour gradient parameter so that I can fix this range to 0-600 for all the plots and thus be able to compare them. Any help would be appreciated.
