Modifying the Y Axis

To change the range, numbering interval, or any other property associated with the x or y axis, first choose the axis (or one of its components), double click on the axis or use the “Edit/Properties” option. The Y-axis has the following properties:

20000000.gif Title – Label for Y-axis displayed to the left of its numbering.

20000000.gif Rescalable -- Specifies as to whether the Y-axis will be re-numbered (scaled) when one of the data points extends beyond its range. Note that re-scaling may modify the tic mark, numbering, and grid line intervals to maintain a similar visual representation of the chart. If this options is not checked, data points falling beyond the limits of the Y axis will be clipped.

20000000.gif Show grid lines -- If the this option is on, grid lines will be shown crossing the Y axis.

20000000.gif Tics centered, Tics inside, Tics outside – Define the tic mark alignment with respect to the Y axis line. Tics marks can be attached to the Y axis from their center, left or right sides.

20000000.gif Minimum, Maximum – Define the initial Y-axis data range of the chart.

20000000.gif Tic Interval (major & minor) – Define the distance along the Y-axis between consecutive tic marks. If an interval is zero, tic marks will not be displayed.

20000000.gif Numbering interval – Defines the distance along the Y-axis between consecutive number labels on the axis.

20000000.gif Grid line interval – Defines the distance along the Y-axis between consecutive grid lines.

20000000.gif X Intersection Point – Defines the point (in y-axis coordinates) along the Y-axis where the X-axis intercepts.

20000000.gif Data scaling factor – Defines the factor multiplied to the Y component of all data plotted to the chart at runtime.
