building Heatmap

Thanks a lot for the superb solution...

I need few more enhancement to the same..may be I am asking too much...but I know you people can only make it work for me.

a) In the heatmap prepared, I need a column with the count of cluster falling under defined range..shown in the file attached..

b) I want that only 10 cluster would be shown in a single line and if clusters are more than 10, it would accomodate in another line and range would also adjust...shown in the file attached.

c) I want to show the uptime% in bracket along with the cluster name.this is also shown for some of the clusters in the file attached...

I am bothering you guys too much..thanks for the cooperation till date..
