It works for the other projections, since the values get transformed to projection coordinates anyway. With merc and cyl, there is no transformation for longitudes. -Jeff -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.

There may be an easier way, but in the past I've used a color converter
object
(which seems unnecessarily verbose):
>>> import matplotlib.colors as mcolors
>>> cc = mcolors.ColorConverter()
>>> cc.to_rgb('b')
(0, 0, 1)

If you have a white background (and no overlapping markers/lines), you
could just set the "alpha" argument in the plot command.

I added these lines:

I still get the "\n" printed literally in the label (an actual carriage

[Matplotlib-users] Matplotlib colors
I want to: 1. Have matplotlib assign the linecolor for a plot 2. Read the linecolor with .get_color() 3. Create another plot with the linecolor set to a lighter version of the previous linecolor. Ie: a, = plot(x,y) a.get_color() = 'b' b, = plot(x,y, color = "#xx") Since I'm only using the standard matplotlib assigned colors which cycle through b,g,r,c,m,y,k I thought I would just create a mapping between each color and a lighter version. How do I get the hex or RGB string for the base matplotlib colors? Also, if there's a different property I can use to lighten the line color without changing the color that would be cool too.

For the example image I use the data provided via TrueColor link. Notes: 1-) Using PyNIO to open hdf-eos files, from ccplot using cctk for 2D data interpolation, basemap for map plotting and numpy/scipy for other essentials. 2-) crefl.1km.hdf is reflectance corrected data using NVDI's crefl program. Set-up TrueColor tutorial and you should be able to get these correction applied data by calling its main script or set-up another. 3-) MOD03.hdf is the geolocation data. 4-) No need to run ms2gt or any other swath to grid conversion tools, since the interpolation routine handles this step. 5-) Code is in 100 lines. Unlike TrueColor tutorial it only works for 1KM resolution. HKM and QKM resolution plotting requires additional steps. It takes about 2.5 seconds to get the plot on my screen.
