Off topic:strange legend in ggplot

Question

[tomasscheitel]

Hi,

I am having difficulties plotting the correct values in my legend on a ggplot + geom_tile

The command I am using is:

ggplot(PlotData, aes(y = start,  x = start.1)) +  
   geom_tile(aes(fill = Substraction)) + 
   scale_size(range = c(1, 200)) + 
   scale_fill_gradientn(
      colours = rainbow(100), 
      values = seq(0,1 , .1), 
      space = "Lab", 
      na.value = "white", 
      guide = "legend") + 
   ggsave(file=paste(PlotName, "_gplots1_1S.pdf", sep=""))

and the data I'. using as an input is a data.frame of dim 17766225x4, which looks line that:

       start start.1 Subtraction bins2
1_1001     1    1001     1.109193    12
1_2001     1    2001           NA    NA
1_3001     1    3001           NA    NA
1_4001     1    4001           NA    NA
1_5001     1    5001           NA    NA
1_6001     1    6001           NA    NA

I would like to show the values of Subtraction in my plot. The range of the data is [0,1].

But when I plot it, I get in my legend values between 0-25. I don't understand where this values are coming from.

Am I plotting the right values? What is happening to my scales?

A snapshot of the plot created with this command can be seen here.

Thanks for any help,

Tomas
