Line Chart Data Colors Based on Column in Dataset
Enable line chart data colors to based off of a column in a dataset that has color hex codes. If the legend field of the chart has many values (such as product rank within a group concatenated with product name), hex codes could be repeated for each rank across the various product groups.
Dynamic Column Headers in Table/Matrix
If header text could utilize a function (such as LOOKUP) that returns a value from a table, you could then have a table with columns named after the top n products.
Synced Scroll Bars
For report pages with multiple visuals with the same axis data (e.g. a clustered bar chart with store locations in the axis field), the ability to sync the vertical/horizontal scrolling on both visuals would greatly improve the ease of use and readability of the report.
