Simplest possible case: 1 vector, no colors, no labels - like xplot "pplot(spectrum)" pausing
2. Simple case: 1 vector with user-input x-axis, no colors, no labels "pplot(spectrum, xaxis=xlab1)" pausing
3. Next simplest case: 1 array, user-input x-axis, no colors, no labels - will cycle colors automatically "pplot(lab_array, xaxis=xlab1)" pausing
4. Array of spectra, 1 color (for all), 1 label, x and y axis labels, key in specfic location Note: Order doesn't matter for colors and labels) "pplot(lab_array, 'Lab Spectra', 5, xaxis=xlab1, xlabel = 'Wavenumber', ylabel = 'Emissivity', key= '1400, .91')" pausing
5. Array of spectra, 1 color (for all), 1 label, standardized lab plot "pplot(lab_array, 5, 'Lab Spectra', lab1=1)" ............................................................................... pausing
6. 1 array, 1 label, no colors specified - will auto cycle through colors and add index to label. Key in bottom right. Standard Mini-TES plot "pplot(array, 'Mini-TES Array', key = 'bottom right', mtes=1)" pausing
7. 2 different data elements with different x axes.
x, y limits, manually make lower x-axis wavelength but linear in cm-1
The x-axis is in wavenumber, but want a plot that is in wavelength on the lower axis
line weight 5, font_size 26, x-axis, y-axis, and plot labels
"pplot({asudata[1:2], asterdata[1:2]}, xaxis={xlab1, xastercm}, {'Lab', 'ASTER'}, key = 'outside', \
wave=1, x1=500, x2=1500, y1=.7, y2=1.05, lw = 5, font_size=26, xlabel='Wavenumber', \
ylabel='Emissivity', plot_title = 'Lab and ASTER Example')"
pausing
8. 2 data elements (1 array & 1 vector), 2 colors, 2 labels - single color and single label for each data element
"pplot({array, avg(array, xy)}, {1,2}, {'Spectra', 'Ave. Spectrum'}, xaxis=xmtes, x1=500, \
x2=1800, y1=.7, y2=1.02, cm=1)"
pausing
9. ASU spectral structure example "pplot(spec_struc)" pausing
10. Resample example - lab, mtes, tes, and themis spectra

"pplot({asu.data[1], a1, t1, th1},{1,2,3,4}, {'Lab','ASTER', 'TIMS', 'THEMIS'}, key='1450,.96', \
xaxis={xlab1, xacm, xtcm, xthcm}, x1=500, x2=1800, y1=.88, y2=1.01)"
pausing
11. write to ps and pdf files. TES default plot, wavenumber on bottom x axis, ps, pdf
"pplot({tes_emiss[1:3,1]}, {'TES Array'}, key = '900, .9', tes=1, emiss=1, cm=1, \
ps=$TMPDIR+"/junk.ps", pdf=1)"
Outputting postscript to file: ./junk.ps
Wavelength on the top
converting to pdf file ./junk.ps.pdf
Using postscript line colors from file: /u/cedwards/.Xdefaults
pausing
Now I'll demonstrate the more esoteric functions and features
3 vectors, 3 labels, no colors - will auto cycle through colors
"pplot({a,b,c}, {'V1', 'V2', 'V3'}, mtes=1)"
pausing
2 data elements, 2 colors, 2 labels in structures - single color and single label for each data element
"pplot({array, xx}, {1,2}, {'a', 'b'}, mtes=1)"
pausing
Just 1 data element with 4 vectors in x, 4 labels, 4 colors
"pplot(array[1:4, 1], {1,3,5,6}, {'a', 'b', 'b', 'd'}, mtes=1)"
pausing
3 data elements, colors WERE specified, one color for each and 1 label for 'a', 'xx', 'yy'
"pplot({array,xx, yy}, {1,3,7}, {'a','xx', 'yy'}, mtes=1)"
pausing
THEMIS default plot, wavelength on bottom x axis "pplot(emthemis_cube, 'THEMIS', key = '1100, .96', themis=1, emiss=1)" pausing
