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 the 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 opens the dialog shown in (Figure 67). 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.

On the Label tab (Figure 68), 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 tab with options for choosing a font,

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

interval marks.
