I have a simple application which polls database for data every minute. When new data is fetched, I am updating the graph using ajax. However, whenever I update the graph (re-plot it with new values added to plot data) the current state of zoom is lost. Before updating the graph, I want to preserve the latest zoom position. After updating the graph, I want to zoom the graph to its saved position. This is important because re-zooming every minute is irritating. Is this possible?
