Field dialogue Fields

 
Field dialogue
  • Model group - when a model group is chosen, the available models are shown.
  • Model - when a model is chosen, one of the available field groups with associated fields is shown.
  • Field group - when a field group is chosen, the available fields are shown.
  • Field - when a field is chosen it will appear in "Selected fields".
  • Selected fields - shows which fields have been chosen. 

    Field buttons
  • Delete removes the marked field.
  • Delete all removes all of the selected fields.
  • Model changes model to the marked model under "models", applies to all fields with the same model as the marked one.
  • Copy copies the marked fields. This allows for showing several levels at the same time.

    Field buttons - earlier commands
  • Up and down button used to go through earlier commands (including earlier Diana sessions). The command is shown under "Selected field".
  • OK (when the button is red) is used to execute the command. (This also checks whether the fields still exist). 
Field buttons
  • Up and down button changes the order of the fields.
  • R resets all attributes (colour, thickness, etc) of the selected field.
  • - The difference between two fields. The selected field is subtracted from the above field. Resolution and all attributes are defined by the first field. Layer, time deviation and time difference are the only attributes chosen separately for the two fields.

Fields, advanced part

This part of the dialogue is shown when the "More > > " button is clicked, and disappears when the " < < Less" button is clicked.
Advanced fielddialogue
  • Min, max size - size of marking (L/H, C/W).
  • Min, max radius - search radius, will change the number of L/H, C/W shown.
  • Smooth lines - smoothes isolines by entering no. of extra points. Gives a nicer look, when a small field-area is displayed.
  • Smooth fields - smoothes fields before they are displayed (for wind-/vectorfields u and v are smoothed separately). No. of smoothing operations is selected. Method: "Low-bandpass filter", which removes short wavelengths ("noise").
  • Grid lines in selected resolution (1=all) shows lines along constant x and y axis.
  • Time offset is used to show fields with different times, the offset is given in hours relatively to "valid time" (negative=earlier, positive=later).
  • Time diff. shows the maximum allowed difference between chosen time and field time. The field closest in time is always chosen.
  • Undefined - marks undefined/missing values in fields, e.g. land point in wave model. Colour, line-thickness and -type can be selected.
  • Numbers on isolines can be turned on/off, and the no.-size can be altered (relative standard-size).
  • Zero-line can be deleted from certain fields (defined in the setup-file). E.g. trend
  • Table - annotation table on the map.
  • Repeat - the palette is cyclic.
  • Palette - change colour palette for selected fields. If "off" is chosen, the field is not coloured. No. of colours in the palette can be chosen and interpolation is done between the first and the last colour "Auto" means the colours from the setup-file is used.
  • Palette (-) - Other colour palette under base value.
  • Pattern - the field is plotted with a pattern. If the colour is set to "auto", the colour from the palette (or the line colour) is used.
  • Alpha value - transparency for selected fields.
  • Base value -
  • Min value - contour lines with values under min value are not displayed.
  • Max value - contour lines with values over max value are not displayed.
  • Extra contour lines - can be used e.g. to draw some contour lines with thicker lines or in other colours.
