Geoff, You can create a large dataset with empty, or 0 values, for your Y Axis. Then when you populate data from your service, add/append those values to the end of your dataset, while removing an equal number of empty values from the beginning of the dataset. If you've created an ArrayCollection of these values, then via binding, it will update the chart automatically as you add/remove values to/from this collection. Have your line chart ignore 0 values and the line won't draw at the beginning, and only begin drawing on the right where you've started populating data.
Continue this process as you receive data, and eventually you will have a full dataset, and as you continue to add/remove values, your full chart line will continue updating appearing to move from right to left. Does all this make sense? I've used a Mac for years now, so I'm pulling from memory what the task manager charts look like, but I think this is accurate. Let me know if you need any clarification on the method I'm suggesting above.
