Formatting the chart elements

Depending on the purpose of your document, for example a screen presentation or a

printed document for a black and white publication, you might wish to use more

detailed control over the different chart elements to give you what you need.

To format an element, left-click on the element that you wish to change, for example

one of the axes. The element will be highlighted with green squares. Then, right-click

and choose an item from the context menu. Each chart element has its own selection

of items. In the next few sections, we explore some of those options.

Formatting axes and inserting grids

Sometimes you need to have a special scale for one of the axes of your chart, or you

need smaller grid intervals, or you want to change the formating of the labels on the

axis. After highlighting the axis you wish to change, right-click and choose one of the

items from the pop-up menu.

Choosing Format > Axis > X Axis or Format > Axis > Y Axis opens the dialog

shown in Figure 79, which in this case is the Scale tab. The fields available on this

dialog depend on the type of chart and whether it is 2D or 3D.

On the Scale tab, you can choose a logarithmic or linear scale (default), how many

marks you need on the line, where the marks are to appear and the increments

(intervals) of the scale. You must first deselect the Automatic option in order to

modify the value for any scale. Selecting the Reverse direction radial creates a

backwards representation of the chart.

On the Label tab (Figure 80), you can choose whether to show or hide the labels and

how to handle them when they won’t all fit neatly into one row (for example, if the

words are too long).

Not shown here are the tabs with options for choosing a font and specific font effects,

formatting the lines, positioning the elements of the line and interval marks, and

selecting effects relating to Asian Typography if this function has been activated in

Tools > Options > Languages.
