1. A method of facilitating selection of elements displayed on a touch screen, the method comprising: sending a plurality of elements for display as a part of a chart on said touch screen, each element being identified by a corresponding value of a first sequence of values in a first dimension and also another corresponding value of a second sequence of values in a second dimension, said first sequence of values and said second sequence of value being aligned respectively along a first axis and a second axis of said chart such that the position of each element in the displayed chart is correlated with the respective values in said first dimension and said second dimension identifying the element; receiving an indication that a user has selected a first element of said plurality of elements, said first element being identified by a first value in said first dimension and a second value in said second dimension; receiving information indicating that a user has performed a swipe in a first direction; checking whether said first direction is closer to said first axis or said second axis in the display of said chart on said touch screen; if said direction is closer to said first axis than said second axis, determining as a desired element, an element of said plurality of elements subsequent to said first element along said first dimension, otherwise determining as said desired element, an element of said plurality of elements subsequent to said first element along said second dimension; and updating said chart to indicate that said desired element is the presently selected element.
