The h-Graph displays the h index for a single author, multiple authors, or a group of selected documents. The h index is based on the highest number of papers included that have had at least the same number of citations. The h index was developed by J.E. Hirsch. Hirsch defines the h index as follows:
"A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np h) papers have no more than h citations each."
| For Example |
An h-graph for a group of selected documents or selected author(s) with an h index of 12 means that out of the total number of documents selected to produce the graph, 12 of the documents have been cited at least 12 times. Published documents with fewer citations than h, in this case less then 12, are considered, but would not count in the h index.
The same is true for the group of selected authors. If the author(s) have an h index of 12, it means that out of the total number of documents produced by the author(s), 12 of the documents have been cited 12 times. |
For more information about the h index, see Hirsch, J.E. "An index to quantify an individual’s scientific research output." Department of Physics, University of California, San Diego.
The graph includes two lines: h index and the h-Line. The h index line represents the number citations received for each of the articles in descending order. The h-Line represents the number of citations equal to the number of articles.
The h-graph includes a Chart and a Data view. The Chart View displays the information as an interactive graph. The Data View displays the information in a table format.
Note: To view the h-graph, you must have the latest version of Adobe® Flash® Player installed and JavaScript™ enabled in your browser. See Browser Requirements and Preferences for more information.
When an h index is calculated for an author, multiple authors, or a group of selected documents, articles published before 1996 are not included in the graph, because complete citation information for articles published prior to 1996 is not available in Scopus.

You can create an h-graph for a single author, multiple authors, or selected documents.
| Note | When you create an h-graph for a single author, graphs that show the number of articles published by an author and the number of citations received by an author are also created. |
Single Author: You can create an h-graph for a single author and any matched authors.
To view an h-graph for a single author
From the Make Author Selection page, do one of the following:
Click on the 
Details link next to the author whose publishing output you want to evaluate. The Author Details page will display.
OR
Select the author whose publishing output you want to evaluate, and then click 
. Either the Citation Overview or the Request Citation Tracker page will display.
| Note |
Excluding author self citations may change hirsch index scoring for an author or a group of authors. |
From the Author Details or Citation Overview page, click 
.
The Author Evaluation Tools page will display.
Note: To include matched authors in your h-graph, click the button in the matched authors column.
Multiple Authors: You can create an h-graph for more than one author from Author Search results. The h-graph will include documents written by all selected authors.
To view an h-graph for multiple authors
From the Make Author Selection page, select the authors that you want to evaluate.
Click .
Either the Citation Overview or the Request Citation Tracker page will display.
From the Citation Overview page, click .
The Author Evaluation Tools page will display.
| Note | If you update your Citation Overview page to exclude author self citations, you may change hirsch index scoring for an author or a group of authors. |
Selected Documents: You can create an h-graph for selected documents from most Scopus results lists.
To view an h-graph for selected documents
From a Scopus Results list, select the documents that you want to evaluate.
Click .
Either the Citation Overview or the Request Citation Tracker page will display.
From the Citation Overview page, click .
The h-Graph page will display.
| Note | If you update your Citation Overview page to exclude author self citations, you may change hirsch index scoring for an author or a group of authors. |
The Chart View displays the h-graph as an interactive graph. The Chart View is the default view.
From the chart view, you can:
View information about data points
You can view more information about a data point on the chart by placing your mouse pointer over that data point. The document number and the number of times the document has been cited will display. The document number indicates where the document falls on the h-graph. For example, a document number of 1 is given to the highest cited paper.
You can adjust the range of data shown in your graph using the Zoom feature. Move the Zoom pointers to the left and right until the range of data that you want displayed is between the pointers. The chart will automatically resize. Show Me
The Data View displays h-graph data in a table. Click a column head to sort the table by that field.
The document number and the number of times the document has been cited will display. The document number indicates where the document falls on the h-graph. For example, a document number of 1 is given to the highest cited paper.
You can change the date range of articles that are included in an h-graph.
From the date range drop-down, select a beginning and ending date range. Values range from 1996 to the current year plus one.
| Note | Complete citation information for articles published prior to 1996 is not available in Scopus. Articles published before 1996 are not used when calculating an h-graph. |
Click 
.
The graph will be updated using the new date range.
You can print and e-mail an h-graph. Only the Chart View of the h-graph will print.
Tip: Set your printer to landscape for best results.
