Hi,
I am trying to plot using the command
cgplot,scan,r_mean,yrange=[-0.7,0.3],xrange=[-50,50], title=TTITLE,BACKGROUND = 255, YTITLE=textlabel,XTITLE='IASI SCAN ANGLE (deg)',COLOR = 3,symsize=1.5, thick=2.3,min_value=-50,FONT =1,CHARSIZE=2.7,xstyle=0
I want my xaxis labels to start with -50 with interval of 10 and end with 50.
But using xstyle=1 does force my plot to -50,50 by the labels are only displayed -40 to 40 with plot extending beyong -40 and 40.
When I use xstyle=0 the plot goes from -60 to 60.
Please help

Add XTICKS=10.

I can imagine. :-)
I would install ImageMagick and do this:
cgps_open, 'example.gif'
cgPlot, ...
cgps_close

Or, more simply, since you only have one cgPlot command:
cgPlot, ..., Output='example.gif'

I guess you are looking for the following information? Incidentally, you should have provided this information during creation yourself, unless you want the default (Helvetica, 12pt, Roman).
IDL> p = plot([0,1], [0,1])
IDL> t = text(0.6, 0.4, 'Some text', font_name='Times', font_size=16)
IDL> print, t.font_name, t.font_size
Times 16.000000
IDL> case t.font_style of 0: print, 'Roman' & 1: print, 'Bold' & 2: print, 'Italic' & 3: print, 'Bold Italic' & endcase
Roman

Or are you looking for the fonts on the plot axes? Those are properties of the plot object P, with the same names:
IDL> print, p.font_name, p.font_size, p.font_style
Helvetica 12.000000 0
or check the properties of the axes "inside" the object P":
IDL> help, p.axes
<Expression> OBJREF = Array[4]
IDL> for ii=0,3 do print, (p.axes)[ii].tickfont_name
Helvetica
Helvetica
Helvetica
Helvetica
IDL> for ii=0,3 do print, (p.axes)[ii].tickfont_size
12.000000
12.000000
12.000000
12.000000
IDL> for ii=0,3 do print, (p.axes)[ii].tickfont_style
0
