Adjust error bar width

Adjust error bars width in an errorbar plot to a ratio of the x-axis or a length (x-axis units).

Description

function errorbar_tick(h,w,xtype)
ERRORBAR_TICK Adjust the width of errorbars

ERRORBAR_TICK(H) adjust the width of error bars with handle H. Error bars width is given as a ratio of X axis lenght (1/80).

ERRORBAR_TICK(H,W) adjust the width of error bars with handle H. The input W is given as a ratio of X axis lenght (1/W). The result is independant of the x-axis units. A ratio between 20 and 80 is usually fine.

ERRORBAR_TICK(H,W,'UNITS') adjust the width of error bars with handle H. The input W is given in the units of the curent x-axis.

Nice work! This has driven me crazy in the past, but not any more .

cool job!! but the feature does not retain when I change linear scale to log scale(i.e. the width is wider in log scale and is uncontrollable)

[Arnaud Laurent]

Re: thanks for your input Sathish, you're right the script wasn't made for log scale. I'll update the file to take care of that.

Thanks very much! Easy to use and works great.

One quick tip, which is relatively obvious but might be nice to add to the help: If you'd like to get rid of the ticks entirely, it's as easy as calling: errorbar_tick(h,0,'units')

good idea, but I'm new to matlab and am unsure of the variables h and xtype, could someone post an example?

[Max]

Works great! Thanks a lot!

[Tobias]

Thanks for sharing your solution! It works fine as long as I one have one error bar series in a plot but I can't get it to work when I have more (as in> errorbar, hold on, errorbar). Do you have a fix for this?

It's great that this function operates on the handle output by the errorbar function, rather than duplicating what the errorbar function already does.

You might want to insert this at line # 39:

if ~isscalar(h)
  arrayfun(@(h) errorbar_tick(h,w,xtype), h);
  return;
end
