graph.bat is a fast Batch utility script to generate bar graphs. Given a file, this script will generate a bar graph into the variable final. For example:
CALL GRAPH "input.txt" /X 1 /Y 2 /C █ /A 3 /YS 5 /W 1 /D 2 /NS 3Will take the data from "input.txt", make a graph at position 1;2 using █ characters, divide the data by 3 with a Y scale of 5, with bars of width 1 and distance 2, and a Y offset by 3. This script only requires a single pass through the data, since to generate the bars, it takes the maximum bar length and subtracts/adds to it, so it doesn't iterate again for each bar.
Each parameter has a default, so you don't have to specify each one. The first argument is always the file name; the rest can be put in any order.

1. Download graph.bat
2. Define %ESC% in your code as the escape character for VT100 sequences
3. Your input file should be a simple file of a number a line. For example:
5
12
8
77
23
4. CALL GRAPH with your parameters
