Plot Demo

Demonstrating the mass-composition plot methods.

import pandas as pd
import plotly
from plotly.graph_objs import Figure
from elphick.mass_composition.datasets.sample_data import sample_data
from elphick.mass_composition import MassComposition

Create a MassComposition object

We get some demo data in the form of a pandas DataFrame

df_data: pd.DataFrame = sample_data()
print(df_data.head())

       wet_mass  mass_dry    FE  SIO2  al2o3  LOI  group
index
0         100.0      90.0  57.0   5.2    3.0  5.0  grp_1
1          90.0      80.0  59.0   3.1    1.7  4.0  grp_1
2         110.0      90.0  61.0   2.2    0.9  3.0  grp_2

Construct a MassComposition object and standardise the chemistry variables

obj_mc: MassComposition = MassComposition(df_data)
print(obj_mc)

Create an interactive parallel plot

fig: Figure = obj_mc.plot_parallel()
fig

Create an interactive parallel plot with only the components

fig2 = obj_mc.plot_parallel(vars_include=['mass_wet', 'H2O', 'Fe'])
fig2

Create a parallel plot with color

fig3 = obj_mc.plot_parallel(color='group')
fig3

Create a ternary diagram for 3 composition variables

fig4 = obj_mc.plot_ternary(variables=['SiO2', 'Al2O3', 'LOI'], color='group')
# noinspection PyTypeChecker
plotly.io.show(fig4)  # this call to show will set the thumbnail for use in the gallery
