plotCustomLayout
==============================================

Purpose
----------------

Plots a graph of user-specified size at a user-specified location.

Format
----------------
.. function:: plotCustomLayout(x_start, y_start, width, height)

    :param x_start: the distance from the left edge of the canvas to the left edge of the custom
        plot expressed as a number between 0 and 1.
    :type x_start: scalar

    :param y_start: the distance from the bottom edge of the canvas to the bottom edge
        of the custom plot expressed as a number between 0 and 1.
    :type y_start: scalar

    :param width: the width of the custom plot expressed as a number between 0 and 1.
    :type width: scalar

    :param height: the height of the custom plot expressed as a number between 0 and 1.
    :type height: scalar

Examples
----------------

::

  // Create an additive sequence starting from -pi and moving
  // forward in 0.1 increments
  x = seqa(-pi, 0.1, 63);

  // Plot the cosine of x
  plotXY(x, cos(x));

  // Create a custom section for the next graph starting 10%
  // from the main graph's left edge, 10% from the bottom of
  // the main graph, with a width and height both equaling
  // 30% of the width of the main graph.
  plotCustomLayout(0.1, 0.1, 0.3, 0.3);

  // Plot the next graph in the custom layout
  plotXY(x[1:20], cos(x[1:20]));

  // Prevent the next graph from being drawn in this custom
  // region
  plotClearLayout();

Remarks
-------

After calling this function all subsequent graphs will be plotted inside
of the specified custom layout until the layout is reset with
:func:`plotLayout`, or the layout is cleared with :func:`plotClearLayout`.
