2.1.1 Examples

We will start off using the file data in your directory. Using the GMT utility minmax we find the extent of the data region:

    minmax data

which returns

    data: N = 7   <1/5>   <1/5>

telling us that the file data has 7 records and gives the minimum and maximum values for the first two columns. Given our knowledge of how to set up linear projections with -R and -JX, try the following:

1. Plot the data as transparent circles of size 0.3 inches.

2. Plot the data as solid white circles instead.

3. Plot the data using 0.5" stars, making them red with a thick (width = 1.5p), dashed pen.

To simply plot the data as a line we choose no symbol and specify a pen thickness instead:

    psxy data -R -J -P -B -Wthinner >! plot.ps
