How saving real time charts?

How can I save real-time charts as GIF?
I added this at the end of my code but it only saves the chart with the last update of the XYSeries:
BitmapEncoder.saveBitmap(this.chart, "./Sample_Chart", BitmapFormat.GIF);

To make the gifs in the README, I did a screen recording and used some free software to convert it to a GIF. There is no suppprt in XChart directly for that.
