IDL contains a number of symbols ready for your use. The symbols are designated using keywords with the Plot command such as: Plot, xvalues, yvalues, PSym=-5, SymSize= SymSize=2 makes the symbols twice as big as "normal." This command draws a graph with xvalues on the x axis, yvalues on the y axis, and the points are indicated by a triangle. Plot the data and add descriptive titles. IDL plot, chirp, xtitle=’Time (s)’, ytitle=’Amplitude (m)’, $ IDL title=’Sine Wave with Exponentially Increasing Frequency’ This statement was too long to fit on a single line in the manual. In IDL, a statement can be broken into multiple lines with the continuation character $. When. Many of the examples in this manual use IDL’s iTools, which provide an interactive graphical interface to visualizations such as plots or images. The iTools use IDL’s Object graphics system, and will automatically adjust to display correctly on any computer running IDL.
The following shows how a plot can be written to an eps file without manual intervention: IDL p=plot(findgen(5),dimension=[,],/buffer) IDL www.doorway.ru,'www.doorway.ru' IDL www.doorway.ru The /buffer keyword sends the plot to a buffer rather than the screen. The dimension is set in pixel units. I notice the size of the www.doorway.ru file is larger than the. 6 IDL Manual Ploting Usetheplotcommandtodisplaycurves. Minimalexample: x = findgen() y = x^2 plot, x, y Youcanalsochangecolorsandoverplotothercurves. To reset to the IDL default values for an individual plot: PLOT,W,F,XMARGIN=[10,3],YMARGIN=[4,2] Multiple plots of equal size can be arranged on one page by setting the system variable!www.doorway.ru, which is a vector specifying the number of plots in the horizontal and vertical directions. For example, to make two plots next to each other.

Plots will not be established in roads, as roads are not considered part of the stand’s net acres for purposes of calculating stand volumes. The acres are calculated through a GIS analysis, which has assigned average buffer widths of 60’ to IDL drivable roads. Therefore, no plot shall be established within 30’ of the center of any road. The last item is by far the most important. The on-line manual has details of every aspect of IDL. If you don’t like on-line manuals, there are manuals on paper in room (Don’t take them out of room , please.) There is also a book called IDL Programming Techniques by David Fanning. (It’s white.
