jfreechart

When rendering a chart with JFreeChart, I noticed a layout problem when the chart's category labels included Japanese characters. Although the text is rendered with the correct glyphs, the text was positioned in the wrong location, presumably because the font metrics were wrong. The chart was originally configured to use the Source Sans Pro Regular font for that text, which supports only Latin character sets. The obvious solution is to bundle an actual Japanese .TTF font and ask JFreeChart to use it. This works fine, in that the output text uses the correct glyphs and it is also laid out

In JFreeChart I'm trying to color different regions of an XY line chart/curve based on y value. I'm overriding the XYLineAndShapeRenderer 's getItemPaint(int row, int col) , however I'm not sure how it handles the coloring of the line between the x s since it's only getting itemPaint on the x (integer values). final XYLineAndShapeRenderer renderer = new XYLineAndShapeRenderer() { @Override @Override public Paint getItemPaint(int row, int col) { System.out.println(col+","+dataset.getY(row, col)); double y=dataset.getYValue(row, col); if(y<=3)return ColorUtil.hex2Rgb("#7DD2F7"); if(y<=4)return
