JavaFX LineChart Performance

Question

I\'ve been trying to improve the performance of LineChart in JavaFX but without great success. I also have found that this seems to be a common problem that some programmers hav

Answer 1

What is improving the performance of charts with many data points, is to remove the 'shape' of the data points.

Over css for example:

.chart-line-symbol {
    -fx-shape: "";
}

or to make sure it's not visible at all:

.chart-line-symbol {
   -fx-background-insets: 0,0;
   -fx-background-radius: 0px; 
   -fx-padding: 0px;
   -fx-shape: "";
   -fx-background-color: transparent;
}

Another approach is to remove some data points from your chart. So for example only use every 3. datapoint or calculate the average of multiple data points.
