I can provide my sample source code if necessary in the near future.
(1) Try to draw real-time candlestick Chart with lines and points together. By lines and points, I mean for example, combination of vertical and horizontal lines to show support point and alert trigger point.
(1a) no need to show arrow; lines are good.
(2a) even rectangles instead of combination of horizontal and vertical lines are OK.
(2) better show at least two candlesticks together -- so far any way is fine: for example,
(2a) side by side
(2b) put two candlesticks on one chart.

Try to use addPaintAfterEp(...) in following potentially helpful examples while following samples provide blank or non-instructive output charts?

Line 45 in ed86318

candleStickRenderer.addPaintAfterEp(new PositionFinancialRendererPaintAfterEP(

Line 58 in ed86318

renderer.addPaintAfterEp(new AbsorptionClusterRendererPaintAfterEP(ohlcvDataSet, chart));

On the other hand, addPaintAfterEp(...) in following can provide Color.MAGENTA as designed

chart-fx/chartfx-samples/src/main/java/io/fair_acc/sample/financial/FinancialRealtimeCandlestickSample.java

Line 117 in ed86318

((RendererPaintAfterEPAware) renderer).addPaintAfterEp(new PositionFinancialRendererPaintAfterEP(positionFinancialDataSet, (XYChart) chart));
