For backtests spanning many years, it would make sense to be able to see the portfolio equity in the backtest report on a log scale. A linear scale visually over-emphasizes equity fluctuations in the latter years, vs. very little fluctuations in the former years. Of course, the drawdown chart takes care of this, and one could export the portfolio equity into a chart and then apply logarithmic scaling.
Still -unless I missed something- it would be nice to have this as a standard option inside the analysis settings dialog.
