Scalebar
Create a scalebar object for x- and or y-axis. Scalebar appearance is configured on creation, through setting of properties, or interactively using a context menu.
Note: For precise positioning, plotboxpos is required.
Features
  • Option to autoadjust scalebar on zoom.
  • Scalebar stays in place on zooming and panning
  • Update scalebar size and appearance interactively from contextmenu
  • Save scalebar appearance to preferences, so next scalebar created will use same appearance.
Example
f = figure();
hAx = axes(f);
imshow('cell.tif', 'Parent', hAx);
pixPerUm = 5;
scalebarLength = 10; % scalebar will be 10 micrometer long
unit = sprintf('%sm', '\mu'); % micrometer
hScalebar = scalebar(hAx, 'x', scalebarLength, unit, 'Location', 'southeast', ...
'ConversionFactor', pixPerUm);
Known Bugs
Scalebar position is not correctly updated when interactive zooming tools are activated and user doubleclicks in axes
