Cartesian linear
================

**X**\ *width*\ [/*height*] or **x**\ *x-scale*\ [/*y-scale*]

- **X** or **x**: Sets the projection type.
- *width* or *x-scale*: Sets the plot size.
- *height* or *y-scale*: Sets the plot height [Optional].

The Cartesian linear projection is primarily designed for regular floating point
data. To plot geographical data in a linear projection, see the upstream GMT
documentation :gmt-docs:`Geographic coordinates
<reference/coordinate-transformations.html#geographic-coordinates>`.
To make the linear plot using calendar date/time as input coordinates, see the
tutorial :doc:`Plotting datetime charts </tutorials/advanced/date_time_charts>`.
GMT documentation :gmt-docs:`Calendar time coordinates
<reference/coordinate-transformations.html#calendar-time-coordinates>`.
