You can create line plots using the PLOT function. In this topic, we will use the PLOT function plot a short series of data elements.
For an additional example of using line plots, see Plot Supporting Information in the Environmental Monitoring Long Example.
year = [1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006]
landings = [2203, 1905, 1573, 854, 1077, 880, 572, 626, 614]
graph = plot(year, landings, TITLE='Horseshoe Crab Landings in Thousands', $
XTITLE='Year', YTITLE='Landings in Thousands', $
You can change the plot title font or add a note using the control icons in the plot window ("Annotate" shown on the left and "Text" on the right):
Alternatively, change plot properties by typing in the following at the IDL command line:
graph.title.font_size = 16
graph.title.font_style = "Bold"
graph.thick = 3
