Boxcharts with space between groups (MATLAB function).

Inspired by Sudhee's question on MATLAB Answers (https://www.mathworks.com/matlabcentral/answers/2120996), the groupedSpacedBoxchart function is a modified version of the base function boxchart. The modified function adds extra space between grouped data in a boxchart visualization, thereby making it easier to distinguish between the groups.

Syntax

• groupedSpacedBoxchart(dataTable,x,y,groups)

• groupedSpacedBoxchart(...,varargin)

• axHandle = groupedSpacedBoxchart(...)

Inputs

• dataTable - Table containing your original data

• x - Name of XData variable (ex. 'Month')

• y - Name of YData variable (ex. 'Temperature')

• groups - Name of the variable you wish to group the data by (ex. 'Year')

• varargin - (Optional) name/value pairs compatible with the boxchart() function

Outputs

• axHandle - Chart axes handle

Examples

 load temperature_data
 plt = groupedSpacedBoxchart(data,'Month','TemperatureF','Year');

 % With optional inputs
 plt2 = groupedSpacedBoxchart(data,'Month','TemperatureF','Year',...
        'BoxWidth',0.5,'MarkerStyle','x','notch','on');
 ylim([20 100]), ylabel('Temperature (\circF)')
 legend(categorical(unique(data.Year)))
