Abstract: A system and a method are disclosed for visually displaying data points using charts on a display screen with limited display area. A fixed magnification area allows presentation of detailed information for some data points compared to other data points that are displayed. The chart can be moved relative to the fixed magnification area thereby changing the data points displayed within the fixed magnification area that present additional information. The relative movement between the chart and the fixed magnification area is triggered by different kinds of inputs from the user including, tilting of the device, swiping with a pointing device and selecting a particular data point.
