if that data item is count from 60 to 90 , i would just need 60 to 90 in the legend. how can i edit it.
I have changed the label name. but it still shows the same name of its original from the data pacakage.

Unlock the chart (very important), then click on the Series item name (the current "name").  Go to the Properties-Chart Text Item window.  Change the entry for Text Source>Source Type from whatever it says to "Text."  Then type in whatever you want the legend to display.  Repeat for all the Series items.
