问题 Using a big space performing long numbers is not a good decision. If I have a graph with a medium scale about 50 000, on the Y axis will be written "50 000, 60 000, 10 000". Can I perform it there like 50 * 10^3 or something else? It's necessary for charts with several scales like here 回答1: Use a tickLabelFormatter on the axis. For example: NumberFormat format = new DecimalFormat("#.#E0"); yAxis.setTickLabelFormatter(new StringConverter<Number>() { @Override public String toString(Number

IMO a separation of concern from the Axis. Any thoughts on a solution? 回答1: After you have shown a stage displaying the chart, call: for (Node n: chart.lookupAll

问题 From what I'm reading it's possible to write JavaFX2 skins via CSS. But I can't seem to find any complete examples of this, a few tutorials here and there, but that's it. Specifically I'm looking for a "dark" skin for JavaFX2. Any ideas of where to find pre-made skins? 回答1: If you read modena.css you'll see an explanation where colors values are derived from * -fx-text-base-color for text on top of -fx-base, -fx-color, and -fx-body-color * -fx-text-background-color for text on top of -fx
