E5.1 Curve plotting

  - Visualise the Input Visualiser icon you created in the tutorial
  
  - Create a new Symbol Plotting icon, set Symbol Table Mode to Advanced
    and play with the settings to get an interesting plot



E5.2 Curve plotting onto map

 - Draw a pre-defined curve onto a map

   Hints:
    - use the Input Visualiser from the Modules (Plotting) icon
      drawer to define the geographical points
    - set to Geo Points and set the slash-separated lists of coordinates
    - if you want a closed curve, repeat the first point at the end
    - visualise some GRIB data and drop this icon into the plot
    - drop the graph_curve icon into the plot, or create your own
      Graph Plotting icon
    - note that there is a Macro function which improves the plotting
      of curves on different projections (mvl_geoline()).


E5.3 Define and plot your own ASCII table data

   - Create a new ASCII text file (currrently you must give it the extension
     of '.csv' in order for Metview to distinguish it from other text files)

   - Enter columns of values, choose a separator chatacter and see if you
     can get the Table Visualiser to plot it

   - You can quickly create large amounts of data from a spreadsheet
     application if you like



E5.4 NetCDF visualisation
  
  - The NetCDF file in the data_sources folder contains another variable which can
    be plotted: v2t. Modify your NetCDF Visualiser icon to plot this variable.

  - Create a new NetCDF Visualiser icon which plots, on an x/y graph, with 
    values of v2t along the x-axis, and v2d along the y-axis.


E5.5 ODB plotting with 'binning' method

  - To see the density of points in a scatterplot, we can use the 'binning'
    method

  - The method requires some explanation, so if you are interested, find the
    'ODB Tutorial (for Metview 4.1 versions)' on the Metview training web page:
     http://www.ecmwf.int/publications/manuals/metview/training/index.html
     and look at page 23 'Defining Binning'.
