# Bar Chart Race Plot [](https://matlab.mathworks.com/open/github/v1?repo=minoue-xx/BarChartRaceAnimation) [](https://jp.mathworks.com/matlabcentral/fileexchange/75167-barchartraceanimation) Copyright (c) 2020 Michio Inoue This repository provides a function that generates a bar chart race plot. ### Requirements: R2019b  # Syntax `barChartRace(X)` draws the animation of the bar chart for each rows of `X`. `X` can be numeric array, table, or timetable. `h1 = barChartRace(X)` returns a handle (`h1`) to the figure with bar chart. `[h1,h2] = barChartRace(X)` returns a handle (`h2`) to the figure with the data description in addition to `h1`. `[ __ ] = barChartRace(X, Name, Value)` to use some Name-Value Pair Arguments. # Name-Value Pair Arguments **'Time':** A vector (numeric or datetime) that represents the time for each raw of `X`. The default is `1:size(inputs,1)` **'LabelNames':** A cell or string vector of the variable names, each element corresponds to each columns of `X`. The default is `"name" + string(1:size(X,2))` if `X` is a numeric array or the name of varialbes if `X` is a table or timetable. **'ColorGroups':** A cell or string vector of color group name. Each element corresponds to each columns of `X`. The default is `"name" + string(1:size(X,2))` if `X` is a numeric array or the name of varialbes if `X` is a table or timetable. Example: With `'ColorGroups' = ['g1','g1','g2','g1','g2']`, the bars of 1st, 2nd, 4th column of inputs will the same color. The default color order will be used. **'NumDisplay':** A number of variable to display from the top. The default is all, `size(X,2)`. **'NumInterp':** A number of datapoints to be generated between each time stamp of `X`. The larger the value is the smoother/slower the transtion. The default is 2. **'Method':** A method for above interpolation. The default is 'linear', but can be 'spline' for more dynamic bar transition. **'GenerateGIF':** If TRUE, GIF animation of bar chart race will be generated. **'Outputfilename':** Output GIF file name **'XlabelName':** The XLabelName, the defaultis "" (emtpy) **'IsInteger':** If TRUE, the text shown next to each bar will be arounded to interger value. The default is TRUE. **'FontSize':** Axes fontsize, the default is 15. **'DisplayFontSize':** The fontsize of the time stamp display, the default is 15. **'YTickLabelRotation':** The angle of the y-axes label text, the default is 0. **'Position':** Location and size of the drawable area, specified as a vector of the form [left bottom width height]. The deafult is 'DefaultFigurePosition' **'GIFDelayTime':** Delay before displaying next image. Delay before displaying next image, in seconds, a scalar value in the range [0,655]. The default here is 0.05 (see imwrite for details) **'Footnote':** String text to display at the bottom right corner of the axes. For multiple lines of text, use a vector of strings. Default is "visualized by MATLAB" # Example See `barChartRace.m` for the detail options. Here's a toy data set and its transition of rankings. The variable A starts from 5th place and move to 1st place in the end. ```matlab addpath("function"); % Some toy (time series) data set maxT = 45; time = 0:50; x0 = 1:5; % initial data rate = (5:-1:1)/100*2; % growth rate data = zeros(length(time),length(x0)); data(1,:) = x0; for ii=2:length(time) data(ii,:) = data(ii-1,:).*(1+rate); end [h1, h2] = barChartRace(data); ```   ```matlab % The gif at the top will be generated by the following setting names = ["A","B","C","D","E"]; barChartRace(data,"IsInteger",false,"LabelNames",names,"GenerateGIF",true); ```  # Scripts There are also some sample scripts which will generate a bar chart race plot. These can be a good example to work through the basic ideas behind the bar chart race animation with graphics object of MATLAB. These script can work with the earlier version of MATLAB. - `barChartRace_UniColor.m`: Single color version - `barChartRace_multiColor_oneBar.m`: Multi-color version with one bar object. - `barChartRace_multiColor_multiBar.m`: Multi0color version with multi-bar objects (for users with R2017a or earlier.) Note: The implementation of a function `barChartRace` is similar to that of `barChartRace_multiColor_oneBar.m` but many additional options.
