graph should not dissappear to left while automatic updating

In the above example data loss is seen...so i suggest a proper panning feature which will allow us to show the previous part of the chart as well..

The data is not lost, what you see is the result of an option in series.addPoint. If you set the shift option to false the data will accumulate.
