gdxcompare 0.1.2

Visually compare time series across GAMS GDX files

1 Purpose

Tool to compare symbols in GAMS Data eXchange (GDX) files with time series data (specifically integer indexed data).

2 Usage

After installing the module, just call

python -m gdxcompare [options] gdx1 gdx2 ...

An HTML page will open up, showing something similar to this screenshot.

• Symbols (variables, parameters) are listed on the left and are selected by left clicking.

• Set dependencies and corresponding elements are listed in adjacent columns. Set elements are selected via mouse hovering.

• The color of the cells indicate the relative variance across elements in a set, so that blue elements will exhibit smaller differences across GDXs than red elements.

• The time series of the queried data is shown on the right. A title reports the description of the selected symbol and the last element selected. The time axis is identified as the first set with integer elements.

• Zooming is supported via horizontal or vertical mouse dragging. Mouse hovering provides details on the top right corner.

3 Requirements

• Python (tested with Python 3.6).

• up-to-date numpy module.

• up-to-date gdxpy (requires manual installation from github).

4 Options

Options

Short version	Long version	Description
-h	--help	Show this options list and exit
-m XMAX	--xmax=XMAX	Max value for x-axis [0 = no max, default]
-f XMIN	--xmin=XMIN	Min value for x-axis [0 = no min, default]
-r RENAME_STRING	--rename=RENAME_STRING	Comma-separated list of new names to give to GDXs (no spaces)
-s SYMB_REGEX	--symb=SYMB_REGEX	Regex for filtering symbols, or lambda starting with @ (e.g. @len(x)<5 for all symbol names shorter than 5 characters)
-p PROF	--profile=PROF	Profile name, used if no SYMB_REGEX specified, associated to a predefined combination of regex for filtering symbols (see here for examples)
-x LAMBDA_EXPR	--xlambda=LAMBDA_EXPR	Lambda function applied to each element of the x-axis
-d	--disaggsymb	Flag to disaggregate large symbols across elements of the first domain

For example:

python -m gdxcompare -sQ -rbau,ref -m20 results_bau.gdx results_ref.gdx

will compare symbols starting with Q of the two GDX files results_bau.gdx and results_ref.gdx in the current path, labelling them as bau and ref, and showing results up to period 20.
