Problem: Text or Markers either do not appear or are in the wrong location

Description

Some or all text or marker symbols may not appear or are in the wrong location on the map.

Cause

The font parameter is set incorrectly.

Solution or Workaround

Verify if the text or symbol has a symbol by using the TEXTINFO <symbol_number> command. If the font parameter is 0, this could cause symbols, especially text, to plot incorrectly or not at all.

The first 21 symbols in PLOTTER.TXT use font 0 and are primarily designed for quick on-screen display.
