bar plot

["Seontae Kim" <stkim@xxxxxxxxxxx>]

Hi all...
How are you guys doing?

I have two questions.....
1) I want to plot bar extending from base to y instead of drawing line. The
data has time values in x-axis and temperature values in y-axis. Can I plot
the bar using "PLOT"?

2) I have a NetCDF formatted dataset whose missing value is -9999.
So, I added the following command.

use precip.nc (time series data)
set variable/bad=-9999 prcp

but, Ferret still recognizes the missing values as the real values.
I mean,  when the line is drawn, the missing values appear in the plot.

What should I do?
Please help me........
Have a good day.....everyone
