mikePlotLib

Overview

A collection of plotting / coloring tools I've been using here and there. Finally I'm putting them into one place. One safe place.

Installation

Should be as simple as

pip install mikePlotLib

SineBow - turn values into colours

create an rgb sinebow that spans a portion of the color wheel between 0 and 100 with 1000 steps

from mikeplotlib.sineBow import SineBow
SB = SineBow(100, mapType='rgb')

get the rgb tuple for value=57.1

SB.makeColor(57.1)                       # (0, 245, 9)

get it as a #hex string

SB.makeColor(57.1, hexFormat=True)       # #00f509

get 25 colours evenly spaced over the region

cols = SB.getNColors(25)

StackedbarGraph - code for making purdy stacked bar graphs

Example usage 1

from stackedBarGraph import StackedBarGrapher()
SBG = StackedBarGrapher()
SBG.demo()

Example usage 2

import numpy as np
from matplotlib import pyplot as plt
from stackedBarGraph import StackedBarGrapher
SBG = StackedBarGrapher()

d = np.array([[101.,0.,0.,0.,0.,0.,0.],
              [92.,3.,0.,4.,5.,6.,0.],
              [56.,7.,8.,9.,23.,4.,5.],
              [81.,2.,4.,5.,32.,33.,4.],
              [0.,45.,2.,3.,45.,67.,8.],
              [99.,5.,0.,0.,0.,43.,56.]])

d_widths = [.5,1.,3.,2.,1.,2.]
d_labels = ["fred","julie","sam","peter","rob","baz"]
d_colors = ['#2166ac', '#fee090', '#fdbb84', '#fc8d59', '#e34a33', '#b30000', '#777777']
fig = plt.figure()

ax = fig.add_subplot(111)
SBG.stackedBarPlot(ax,
                   d,
                   d_colors,
                   xLabels=d_labels,
                   yTicks=7,
                   widths=d_widths,
                   scale=True
                  )
plt.title("Scaled bars with set widths")

fig.subplots_adjust(bottom=0.4)
plt.tight_layout()
plt.show()
plt.close(fig)
del fig

cbCols - Easy access to the colorbrewer2.org maps

Example usage 1 - see all available colours

from cb2cols import Cb2Cols as CB2
cb2 = CB2()
cb2.demo()

Example usage 2 - the first three colours from qualset1

from cb2cols import Cb2Cols as CB2
cb2 = CB2()
col_set = "qualSet1"
colours = cb2.maps[col_set].values()[0:3]
