I see that the layout options 'Group', 'Crosstab' and 'OLAP' options are greyed out under the 'Data' tab of the chart expert. Is there something wrong with my installation. Thanks in advance
These options are enabled based on the report type. So to use Group, Crosstab or OLAP for charting you will need a group in your report (with a summary field) or a crosstab or design the report off of an OLAP datasource.
