The following examples illustrate the differences in how curves are plotted in Metview 4 compared with Metview 3. The differences are summarised here:

• the curve() function is replaced by the input_visualiser() function to define the curves. The Input Visualiser provides a way to plot lists of values in various ways.
• the curveview is replaced by the cartesianview. The Cartesian View is a general X/Y coordinate system suitable for any non-map-based plot. The Curve View does not exist in Metview 4.

• the axis limits are defined within the Cartesian View, not in the Axis definitions - these are now only for visual attributes of the axis; the View contains all the information for setting up the coordinate system
• the custom legend entries are defined in the legend() function - Metview has a new Legend icon for controlling the legend.
• use of mgraph() instead of pgraph(), etc. These are the Magics++ versions of the visual definition icons.
• specification of output plot files is a little different
