Citations diagram in results page - wrong start value (0, instead of 1)

[ehenneken]

Expected Behavior

The "Citations" tab in the diagram box on the right in the results page indicates the H-index by drawing lines. The H-index for a given set of papers is the index in the citation-ordered list of publications where the number of citations stops being larger or equal to the rank number. The vertical axis represents the number of citations and the horizontal axis represents the rank number. The H-index line that intersects with the horizontal axis should do so at the value of the H-index.

Actual Behavior

Since the horizontal axis starts counting at 0, rather than 1, the H-index line intersects the horizontal axis at the incorrect value.

Steps to Reproduce

For example, do the query author:"Henneken,E" and select the Citations diagram: the H-index is 8, but intersects the horizontal line at 7.
