i create mxn grid of charts - similar for in m*n: ax = fig.add_subplot(m, n, + 1) for matplotlib there appears supporting classes - within org.jfree.chart.block package. have been unable locate documentation, examples, testcases using arrangement/layout set of charts. pointers appreciated. this part of api rather low-level, , used internally jfreechart. example, gridarrangement may used create particular legend layout , within chart . in opinion, easiest way create grid of charts, use swing jpanel , gridlayout , , fill grid charts. jpanel grid = new jpanel( new gridlayout(m,n) ); for(int i=0; i<m*n; i++) grid.add(new chartpanel(createchart(i))); you can use combinedplot . allows add many plots want, either layed out side-by-side, or stacked vertically (but not on grid, far know). thing approach plots directly share common axis, , aligned nicely. (but depends on problem: charts share 1 common axis ? perhaps 2 ?)
