The Numeric Axis Grids & Scales dialog box (on the Graph menu, click Grids and Scales) is used to
format graph axes, gridlines, and perform scaling. The tabs on the left of the dialog box indicate the
available axes in the graph: Category Axis, Y1 Axis, Y2 Axis (for dual-axes graphs), X Axis (for bubble
and scatter graphs), and Series Axis (for 3D graphs).

When you select an axis tab, the tabs at the top of the dialog box will change to reflect the available
formatting options for that axis. Each axis is described in this section:

Category Axis - All graph types, except bubble, histogram, and scatter graphs, have a category axis.

The category axis defines the groups of items that are being graphed. When category axis labels are
displayed, the labels are taken from the first row in your table.

Y1 Axis - All graph types except pie graphs have a Y1 axis, or primary numeric axis. This axis plots

the values from the rows and columns in your table.

Y2 Axis - Area, bar, bubble, column, line, and scatter charts can be drawn on two numeric axes, Y1

and Y2. When a dual-axes graph is selected, MapInfo Professional automatically divides the number
of series in half and assigns half of the series to one axis and the other half to the second axis. The
two axes can be drawn up or out from the same plane/base line or physically split into two separate
sections on the graph.

X-Axis - Bubble, histogram, and scatter graphs include an X-axis. These graphs have two numeric

axes-a Y1 axis that is drawn on the left side of the graph and an X axis that is drawn on the bottom of
the graph frame.

Series Axis - A series axis is included only in 3D riser and 3D surface graphs. The series axis is also

called a secondary ordinal or O2 axis. In two-dimensional graphs, the series or rows of objects being
graphed are shown in the legend area of the chart. In 3D graphs, these objects are shown on the
series axis, which is on the lower left side of the 3D graph.

Specifying Titles for Your Graph

On the Graph menu, click Titles to specify titles for your graph. In the Titles dialog box, check the boxes
next to the titles that you want to display in the graph.
