Setting Curve Attributes

Select Options ® Curve attributes to call up the Curve Attributes dialog box.

This dialog box lets you set the appearance of the curve in the graph.

The Default button at the bottom of the dialog box lets you reset all Curve Attributes options to their system defaults.

The options provided in the Curve Attributes dialog box are described below.

The Legend Text Option

The Legend text option allows you to enter the text name for the curve. This name appears as the curve title in the legend.

If you want to enter a longer description for the curve, use the Description option. This description also appears in the legend.

The Description Option

The Description option allows you to enter the text that describes the curve. This description appears in the legend under the curve title.

If the Description text is not visible when you call up the legend, you must enlarge it (the legend). See "Using the Legend," later in this section for details on how to do this.

The Curve Number

The Curve number option lets you set the "current curve." You need this option when your graph contains more than one curve: it tells SAP Statistics which curve you are modifying. Curves are numbered: just click on the up or down arrows until the number of the curve you want appears.

Each time the curve number changes, the rest of the menu options display the current settings for the curve designated.

In particular, the Description field reminds you which curve is named by a given curve number.

The Attribute ID Option

The Attribute ID option lets you save attribute settings and reuse them from graph to graph. As a result, you can format separate graphs (whose curves have related meanings) with a consistent set of attributes.

An attribute setting consists of all the options in the menu (including the legend and description texts). You can save up to 255 attribute settings, each identified by a number (the Attribute ID value).

The Color Option

The Color option lets you change the color of the curve.

Simply click on the up- and down-arrow to choose the number of the desired color. Or position the cursor where the numeric value is, delete the entry and re-type it.

The possible colors are numbered from 0 to 63. These are the same colors as those in the color palette of the Color assignment menu.

You can choose a color by number by finding the equivalent color in the palette. The colors in the palette start with number 0 in the upper left and end with 63 in the lower right.

The Width Option

The Width option lets you change the width of the curve's line. Possible values are from 0 (thinnest) to 20 (thickest).

If the curve has been designated as a Markered, Area, or Stepped area curve (in the Curve type option), the Width option has no effect.

The Curve Type Option

Use this option to choose how the curve is represented in the diagram. Only one curve type can be active at a single time. Possible curve types are:

  • Continuous

A smooth continuous line. If you choose a continuous curve, you simultaneously activate the Continuous curves option. This latter option lets you choose what kind of continuous curve you want to see.

  • Markers

A series of markers at selected points. If you choose Markers, you activate the Markered curves option. This latter option lets you choose what kind of markered curve you want to see.

  • Area

Like a Continuous curve, but with the area under the curve colored. The Color value is used to color in the area.

  • Histogram

A series of vertical rectangles, one for each data value. The Color value is used to color in the rectangles.

  • Stepped line

A "rectangular-ized" curve: it consists entirely of vertical and horizontal segments that approximate the smooth Continuous curve.

  • Stepped area

Like a Stepped line curve, but with the area under the line colored. The Color value is used to color in the area.

The Continuous Curves Option

This option lets you choose what kind of line pattern you want for displaying a curve. To use this option, the Curve type option must be Continuous, and the Width option must be 0.

The choices listed in the Continuous curves option include some that are not literally continuous; rather, a continuous curve is suggested by a series of dots or dashes.

The Markered Curves Option

This option lets you choose what kind of markers you want for displaying a curve. In order to activate this option, you must set the Curve type option to Markers. Otherwise, you cannot set any values in this menu.
