Improved Stacked Bar Graph
I have updated the jzplot class to include an additional type of stacked bar graph, "sbarn", that accepts negative values.
Examples
load'plot' (],:|.)@:(,|.@:-) i.5 0 1 2 3 4 _4 _3 _2 _1 0 0 _1 _2 _3 _4 4 3 2 1 0 'sbarn' plot (],:|.)@:(,|.@:-) i.5
'sbarn; barwidth 1' plot (],:|.)@:(,|.@:-) i.5
Setting the EDGECOLOR option to -1 draws the edges the same colors as the bars.
'sbarn;barwidth 1;edgecolor _1' plot_jzplot_ (],:|.)@:(,|.@:-) i.5
Here is a more realistic example showing the changing contribution of each series plotted with the total.
dat=: |:(+0.5-[:?0$~#)^:(<100) 0 _4 4 0 pd 'new' pd 'type sbarn; edgecolor _1; barwidth 1;xtic 10 2' pd dat pd 'show' pd 'type line;color 0 0 0; pensize 2;xtic 10 2' pd +/dat pd 'show'
Plot Class
The updated jzplot class is File:Jzplot.ijs.
jzplot subclass
I have attempted to subclass the jzplot class instead of changing its source. The subclass script is File:Tcplot.ijs. However, this is not working. I don't have much experience working with classes in J; if anyone can figure out why it doesn't work please let me know and update the script.
