Not sure if this is the place for suggestions. The Chart Tool is somewhat helpful, but could be improved with options for how to display frequency search data. The donut/pie charts provide percentages; the rest are impressionistic (e.g., screenshot 1). The following suggestions are based on my regular use of BW data, which are helpful for data but an eyesore for actual presentation (see the options in screenshot 2).
1. Frequency counts: toggled on/off, display with/without percentages, etc.
2. Options for how data is displayed: frequency by book, frequency/% by chapter, etc. (depending on data types, in my case morph).
3. Label toggle on/off for displaying this chosen option for exporting the chart.
4. User defined title for prettifying the export options with some basic font options (esp. Unicode compatibility), using the actual search as a starting point for user modification/replacement.
