I want to be able to use custom expression for labels in all visualizations such as bar charts and line charts. In current version of Spotfire, only scatter plot allows custom expressions. There are cases where I want to display calculated values for bar charts, or attach comments to individual points in line chart. I want to note that the requested feature above is different from the annotation feature implemented in Spotfire 7.5; annotation feature cannot use the data table value to generate comments.
