Read in tutorial data and show a summary¶
This gallery uses the scenario data from the first-steps tutorial.
If you haven’t cloned the pyam GitHub repository to your machine, you can download the file from https://github.com/IAMconsortium/pyam/tree/main/doc/source/tutorials.
Make sure to place the data file in the same folder as this script/notebook.
import matplotlib.pyplot as plt
import pyam
df = pyam.IamDataFrame("tutorial_data.csv")
df
<class 'pyam.core.IamDataFrame'>
Index:
* model : AIM/CGE 2.1, GENeSYS-MOD 1.0, ... WITCH-GLOBIOM 4.4 (8)
* scenario : 1.0, CD-LINKS_INDCi, CD-LINKS_NPi, ... Faster Transition Scenario (8)
Timeseries data coordinates:
region : R5ASIA, R5LAM, R5MAF, R5OECD90+EU, R5REF, R5ROWO, World (7)
variable : ... (6)
unit : EJ/yr, Mt CO2/yr, °C (3)
year : 2010, 2020, 2030, 2040, 2050, 2060, 2070, 2080, ... 2100 (10)
Meta indicators:
exclude (bool) False (1)
First, we generate a simple stacked line chart of all components of primary energy supply for one scenario.

We don’t just have to plot subcategories of variables, any data dimension or meta indicators from the IamDataFrame can be used. Here, we show the contribution by region to total CO2 emissions.
