[matplotlib-devel] errorbar - end bars not visible
Simple example: the bars on the two x axis ends are not visible. x = [3, 6, 10] y = [1, 2, 3] import matplotlib.pyplot as plt plt.errorbar (x, y, 0.2) plt.show() -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

That behaviour of autoscale appears to be consistent with plt.plot(range(3)), for example. That is, the axis limits butt up against the plotted data. By 'work correctly', do you mean that the axis limits should be padded so there is a whitespace border surrounding the data being plotted? -- Damon McDougall http://www.damon-is-a-geek.com Institute for Computational Engineering Sciences 201 E. 24th St. Stop C0200 The University of Texas at Austin Austin, TX 78712-1229 -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

The most obvious way to improve it would be to select axis limits a bit larger. At least large enough to completely show the error bar; I suspect a bit of whitespace would be even more clear. -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

Indeed, I do agree. I have actually changed my mind about this behaviour being consistent with plt.plot. I feel like the 'feet' on the error bars should be taken into account during the autoscaling procedure. This will result in the autoscaling procedure adding a small amount of whitespace such that the feet are then visible after a call to plt.show(). I have opened a new issue on our github issue tracker. See https://github.com/matplotlib/matplotlib/issues/1711 Thanks for reporting the problem, Neal. -- Damon McDougall http://www.damon-is-a-geek.com Institute for Computational Engineering Sciences 201 E. 24th St. Stop C0200 The University of Texas at Austin Austin, TX 78712-1229 -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
