ploterr is a universal tool for plotting data with error bars. The following features are supported:
- linear/logarithmic scaling
- x and/or y error bars
- relative/absolute errors
- width of bar handles adjustable
Basically it unifies the features of errorbarxy, errorbarloglog, errorbar_x and errorbar in one single program.
For a detailed description and examples see the documentation in the file.
The technique for plotting the error bars is adapted from MATLAB's v6 errorbar, which is also used by Goetz Huesken's errorbar_x. With this technique the x error bars as well as the y error bars are one big line object, in contrast to errorbarloglog where each single error bar consists of three separate lines. That prevents an overflow of the legend with lots of separate line objects and makes it a lot easier to change the line style of the error bars.
