Line chart with shaky lines, where none should be

[Festo AG & Co. KG]

At the end of the graph and at the highest point of the curve, it is possible to see eruptions that are not present.
If the curve is zoomed in minimally, the jagged areas disappear.

See http://jsfiddle.net/QwZuf/771/

At this zoom level we should get a clean straight line.

Since we want to visualize measurement data, this issue could be a show stopper for our customer.

@festo,

When zoomType is “x”, viewports of y axis will be calculated based on the dataPoints present within the zoomed region. But when zoomType is “xy”, viewports of y axis depends on the zoomed region. Because of this, you won’t be able to observe the variation in data when zoomType is “xy”. We would recommend you to try the same with zoomType “x”, which would be better as per your requirement. If that doesn’t fulfill your requirement please share some more details, so that we can look into it and help you better.
