I have a data.frame which I would like to plot using the ggplot2 package.
This is what i am doing:
myBreaks <- c(seq(0,0.001, 0.0002),seq(0.002,0.01,0.005), 0.01, seq(0.2,1,0.3), 2,5)#create the intervals PlotData$bins <- findInterval(PlotData[,3],myBreaks) # plotting the braks cols <- c('cadetblue1', 'cadetblue3', 'cadetblue4', 'cadetblue', 'burlywood', 'burlywood2', 'burlywood4', 'brown3', 'darkorchid4', 'darkorange2', 'darkolivegreen3', 'red3', 'midnightblue', 'chocolate2') # wanted colours ggplot(PlotData, aes(y = start, x = start.1)) + labs(title = "normalized values") + geom_tile(aes(fill = bins)) + scale_fill_gradientn(name = "values", breaks = myBreaks, colours=cols, labels = format(paste("\u2265", myBreaks,sep="")), values= myBreaks, rescaler = function(x, ...) x, oob = identity, na.value="grey89", guide="legend")
the plot I get shows all the colours in the plot itself but not in the legend. How can I convert the legend to also show all the colours as well as the breaks as labels?
Thanks in advance
