title: Coordinates of a point - ios-charts [Swift]
body: <p>I searched in the library for two days and unfortunately I'm not able to find out how to get the space between two data in px. My <code>linechartview</code> is contained in a <code>UIScrollView</code> and the aim is to get the value of the <code>linechartview</code> point which is located in the center of <code>ScrollView</code>.</p>
