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 values 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, wherein said chart is a graph, wherein said graph contains a respective group of elements of a plurality of groups of element associated with each value of said second sequence of values, each group of elements containing one or more elements having the same value in said second dimension; receiving an indication that a user has selected a first element of said plurality of elements displayed on said touch screen, 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 direction on said touch screen after having selected said first element; checking whether said 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, a single element of said plurality of elements subsequent to said first element along said first dimension, otherwise determining as said desired element, another single element of said plurality of elements subsequent to said first element along said second dimension, said single element being identified by a third value in said first dimension and a fourth value in said second dimension; and updating said chart to indicate that said desired element is the only presently selected element among all of said plurality of elements displayed as said part of said chart, wherein all of said plurality of elements, including said first element, said single element, and said another single element, are displayed on said touch screen upon said sending, upon said updating, when said user selects said first element and when said user performs said swipe, wherein each of said plurality of elements, including said first element and said single element, is a corresponding graphic element displayed at the respective position defined by values in said first dimension and said second dimension while covering a respective display portion of said touch screen, and wherein said single element is in the same group of elements if said direction is closer to said first axis and in a different group of elements if said direction is closer to said second axis.
