Graph Axes / False Dividend yield

I just logged in for a trail period and loaded up a couple of dummy shares into the portfolio. Just having a play and pretty soon saw a couple of issues: the share price graphs shows prices to the nearest cent - many of the smaller mining stocks trade in 0.1c increments so it's pretty useless for those one dummy stock I entered was DGR.AX that is showing as a ~16% dividend yield - never paid a dividend in living memory the AI help doesn't really seem to be able to answer questions also on the charts no volumes are shown - is this something you plan on adding? As a user I would be looking to manage the portfolio, as your system promotes, but also would have liked to browse stock performance on the charts, volumes etc. Anyway, thanks for the free trail to assess the software.
