Chart with breaks

[akush2007]

I want to draw line chart with breaks in that. The problem statement is to draw line chart after getting data from server and if any data retrieval fails, there would be a break in line and an error icon is shown just below x-axis for it.
I was thinking to break the line and put scatter on those points with image.
My y-axis is NumericAxis. Should I need to convert it to CategoryAxis as NumericAxis is not allowing to give null data point.

You may use a NumericAxis and add Double.NaN to insert a break.

Thanks I was able to solve this.

Though it didn't solve my purpose fully.
I am trying to get a chart like this:

But I am getting chart like this:

The fill is not proper and it is also appearing where there is break in line.
I have added the following line to code:

series.setFill(new RGB(166, 17, 32));

I have written the following but its not helping me.

series.setFillRenderer(new SeriesRenderer<Data>() {
            @Override
            public void spriteRenderer(Sprite sprite, int index,
                    ListStore<Data> store) {
                if(store.get(index).getData()==Double.NaN) {
                    System.out.print(store.get(index).getData());
                    sprite.setFill(Color.NONE);
                } else
                    sprite.setFill(new RGB(166, 17, 32));
            }
            
        });

Please tell me what I am missing.
