/* ============================================================
   INDICATOR PANES - legend and settings dialog (js/indicator-panes.js)

   The legend sits over the chart at the top of each pane, the way
   TradingView's does: "RSI 14 close 60.39 62.35", the values in their
   plot's colour, hide / settings / remove on hover (on a tap on a touch
   screen). In Arabic it mirrors to the other side of the pane, clear of
   the price scale; the figures stay left-to-right (css/locale.css rule).
