# Known limitations

It is not possible to use inline data (e.g. plot '-' ...) inside the curly brackets of a do or while loop.

X11 terminal: It is difficult to select UTF-8 fonts. Only one color palette at a time is active for any given x11 plot window. This means that multiplots whose constituent plots use different palettes will not display correctly in x11.

Qt terminal: 3D rotation of polygons and surfaces can be slow; this is strongly affected by the Qt rendering mode (see Qt documentation).

The raise and lower commands are unreliable.
