Most JClass Chart components support a rich text format called "JCString", which allows a mixture of hypertext, images and text within Chart components. Text can also appear in a variety of colors, fonts and styles, including underline and strikeout.

The following section describes the types of JCString properties available, and provides examples of their use.

Alignment

If a cell contains an image, the line height can, in some cases, be greater than the height of the text. Text can be aligned vertically using the ALIGN property. Valid values include TOP, BOTTOM and MIDDLE. The following example uses all three possible ALIGN values:

([IMAGE=smiley.gif][ALIGN=TOP]top [IMAGE=smiley.gif][ALIGN=MIDDLE]middle [IMAGE=smiley.gif][ALIGN=bottom]bottom)

Color

Different text colors can be specified by using the COLOR property. The JCString shown below displays text using red, green and blue colors.

([COLOR=red]Red, [COLOR=green]Green, [COLOR=blue]Blue, [DEFAULT_COLOR]Default)

In addition to these colors, any color referenced in Appendix A can be used, including RGB color values.

Note: The property DEFAULT_COLOR resets the text color in the rest of the table to the browser's regular text color.

Fonts

Different fonts can be specified within a single cell or label by using the FONT property. The following JCString example displays text using a variety of fonts and font styles.

([FONT=timesroman-plain-20]TimesRoman-20, [FONT=timesroman-bold-12]TimesRoman-12 bold, [DEFAULT_FONT]Default)

Note: The property DEFAULT_FONT resets the fonts in the rest of the table to the browser's regular font.

Horizontal and Vertical Spacing

Vertical and horizontal spacing can be modified by using the VERT_SPACE and HORIZ_SPACE tags. VERT_SPACE offsets the current line by a number of pixels, and HORIZ_SPACE offsets the line from the margin by a set number of pixels. The example below makes use of the HORIZ_SPACE and VERT_SPACE tags.

([VERT_SPACE=10]Vertical offset=10 [HORIZ_SPACE=10] Horizontal offset=10)

Hypertext

Hypertext links can be specified within a cell. The link appears underlined, and the browser display will show the target URL when the mouse cursor passes over the linked text. Hypertext uses the HREF property, and trackCursorPosition must be set to true in order for the link to work. The example below links to KL Group's home page:

(Click [HREF=http://www.klg.com]here[/HREF] for tech support \n [HREF=http://www.klg.com]
[IMAGE=http://www.klg.com/images/technical.gif][HREF])

Images

Images can be specified in a cell by using the IMAGE property. A URL or file name must be provided. If a relative path is given, the document base for the page is assumed. The example below mixes an image with text.

(Tech Support: [IMAGE=http://www.klg.com/images/technical.gif])

Reset

The RESET property resets the font and color to the default value used by the browser. The following example changes the COLOR and FONT values back to the default:

([COLOR=green][FONT=timesroman-plain-20]Big text [RESET]Regular Text)

Strikethrough text

Text can be crossed-out using the STRIKEOUT property. The following incorporates text that has been stuck through:

(This text is [ST]crossed-out[/ST].)

Underlined text

Text can be underlined using the JCString UNDERLINE property. The following example incorporates underlined lined text:

(This text is [UL]underlined[/UL].)
