One of the great benefits of running online workshops is that it pushes me to refine my solutions.
The cornerstone of Tuesday’s visualization workshop is the HTML calculated column. So for the occasion I revisited my script and worked on several improvements. The main one is to make the filter menu work for HTML calculated columns (see screenshot).
Another enhancement I am working on is to allow the use of HTML calculated columns for grouping (see second screenshot).
The first to benefit from the improvements will of course be the workshop participants, as the filter menu will be included in the script they’ll receive. The complete version (v3) of the HTML Calculated Column with all the enhancements should be published by the end of the year.
Update [11/01/2009] Another screenshot of my work in progress: HTML calculated columns used for two level grouping.
