Plotting a map¶
How to create a plot of a map.
import matplotlib.pyplot as plt import astropy.units as u import sunpy.map from sunpy.data.sample import AIA_171_IMAGE
We start with the sample data.
aiamap = sunpy.map.Map(AIA_171_IMAGE)
Let’s plot the result. Setting the projection is necessary to ensure that pixels can be converted accurately to coordinates values.
The above image looks “dark” because the color scale is accounting for the
small set of pixels that are extremely bright. We can use the keyword
clip_interval to clip out pixels with extreme values. Here, we clip out
the darkest 1% of pixels and the brightest 0.01% of pixels.
