For number columns in data panel, a histogram is shown to visualize the data distribution. We also need a similar way to visualize the distribution of data for string columns. The way to do this is to visualize the counts for each unique category value. The 2 options are a bar chart or showing numerical counts associated with each unique category. Horizontal Bar chart would fit in current format - at the top of the data panel and / or in the 'Unique' categories tab.
In the new Data Panel in Spotfire X there is histogram for columns with numeric data type. This is very useful. You should create similar histogram at the same place for category data as well.
