Display

Usage:

display model_var identity_var

This command plots each component of the model variable as a function of time. The identity variable is used to ensure continuity of the curves, and colouring them to aid identification of species. The index of the component is not a good proxy for this, as the index of a particular species may have changed through a condense operation.

Traditional Eco Lab usage of this command is

display ecolab.density ecolab.species

The colour of the lines used are controlled by the palette TCL variable.(§6.7) This is a list of X-window colours to use.

The namespace for this widget is constructed by appending the 1st argument to the string “display_”. Any unacceptable characters are replaced by '_', so it may take a little experimentation to find the correct namespace name. display supports the following methods:

• display_model_var::print filename -- produce a postscript representation to a file
• display_model_var::clear -- clear the plot
