Chart Legend
You can specify whether a legend appears on the chart using the settings on the Legend page. If a series field is used, the legend shows the different series values. If no series field is used, the legend shows the different category values. This page has the following options:
Show legend: turn this option on to display a legend on the chart.
Placement: this option specifies where the legend appears on the chart. The choices are Left, Right, Top, and Bottom.
Style: use this option to specify how the legend is formatted. The choices are different if you have a series field than if no series field is used. Plain means the legend includes category names (or series names if a series field is specified) only with no values. Values at Left and Values at Right, which are only available if no series is used, mean the values for each category appear, either to the left or to the right of the category name. Percent at Left and Percent at Right, which are only available if no series is used, mean each category's value appears as a percentage of the total, either to the left or to the right of the category name. Checkboxes, which is only available if a series is used, indicates the legend includes check boxes which you can use to display or hide certain series (turn off the check box to hide a series).
Font: the font name, size, and style to use for the text in the legend. To change any of these, click the font selection button (...) and select the desired font name, size, and style from the Font dialog that appears. Note that if you select a font script other than Western, the script name (such as "Greek") appears after the font name, size, and style.
Color: the color to use for the text in the legend. To change the color, click the colored square beside this setting and select the desired color from the dialog that appears.
Gradient: turn this setting on to display a gradient of color across the legend.
From color: this option, which is only available if Gradient is turned on, specifies the starting color for the gradient. To change the color, click the colored square beside this setting and select the desired color from the dialog that appears.
To color: this option, which is only available if Gradient is turned on, specifies the ending color for the gradient. To change the color, click the colored square beside this setting and select the desired color from the dialog that appears.
Direction: this option, which is only available if Gradient is turned on, specifies in which direction the gradient flows. The choices are Top to Bottom, Bottom to Top, Left to Right, Right to Left, From Center, From Top Left, From Bottom Left, Radial, Diagonal Up, and Diagonal Down.
