• <b>…</b> displays the text in bold.
• <i>…</i> displays the text in italics.
• <u>…</u> underlines the text.
• <s>…</s> Strike-through text
• <a id;options>…</a> displays an anchor element that can be clicked. An anchor is a piece of text or some other object (for example an image) which marks the beginning and/or the end of a hypertext link.The <a> element is used to mark that piece of text (or inline image), and to give its hypertextual relationship to other documents. The control fires the AnchorClick event when the user clicks an anchor element. Use the FormatAnchor property to specify the visual effect for anchor elements. For instance, if the user clicks the anchor <a1>anchor</a>, the control fires the AnchorClick event, where the AnchorID parameter is 1, and the Options parameter is empty. Also, if the user clicks the anchor <a 1;yourextradata>anchor</a>, the AnchorID parameter of the AnchorClick event is 1, and the Options parameter is "yourextradata". You can use the <a> anchor elements to insert hyperlinks to cells, bars or links.
• <font face;size>…</font> displays portions of text with a different font and/or different size. For instance, the <font Tahoma;12>bit</font> draws the bit text using the Tahoma font, on size 12 pt. If the name of the font is missing, and instead size is present, the current font is used with a different size. For instance, <font ;12>bit</font> displays the bit text using the current font, but with a different size.
• <fgcolor=RRGGBB>…</fgcolor> displays text with a specified foreground color. The RR, GG or BB should be hexa values and indicates red, green and blue values.
• <bgcolor=RRGGBB>…</bgcolor> displays text with a specified background color. The RR, GG or BB should be hexa values and indicates red, green and blue values.

• <r> Right aligns the text
• <c> Centers the text
• <img>number[:width]</img> inserts an icon inside the text. The number indicates the index of the icon being inserted. Use the Images method to assign a list of icons to your chart. The last 7 bits in the high significant byte of the number expression indicates the identifier of the skin being used to paint the object. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the part. The width is optional and indicates the width of the icon being inserted. Using the width option you can overwrite multiple icons getting a nice effect. By default, if the width field is missing, the width is 18 pixels.
• <img>key[:width]</img> inserts a custom size picture into the text being previously loaded using the HTMLPicture property. The Key parameter indicates the key of the picture being displayed. The Width parameter indicates a custom size, if you require to stretch the picture, else the original size of the picture is used.
• & glyph characters as &amp; ( & ), &lt; ( < ), &gt; ( > ),  &qout; ( " ) and &#number ( the character with specified code ), For instance, the &#8364 displays the EUR character, in UNICODE configuration. The & ampersand is only recognized as markup when it is followed by a known letter or a # character and a digit. For instance if you want to display <b>bold</b> in HTML caption you can use &lt;b&gt;bold&lt;/b&gt;

Also, newer HTML format supports decorative text like follows:

• <gra rrggbb;mode;blend> ... </gra> defines a gradient text. The text color or <fgcolor> defines the starting gradient color, while the rr/gg/bb represents the red/green/blue values of the ending color, 808080 if missing as gray. The mode is a value between 0 and 4, 1 if missing, and blend could be 0 or 1, 0 if missing. The <font> HTML tag can be used to define the height of the font. Any of the rrggbb, mode or blend field may not be specified. The <gra> with no fields, shows a vertical gradient color from the current text color to gray (808080). For instance the "<font ;18><gra FFFFFF;1;1>gradient-center</gra></font>" generates the following picture:

  

• <out rrggbb;width> ... </out> shows the text with outlined characters, where rr/gg/bb represents the red/green/blue values of the outline color, 808080 if missing as gray, width indicates the size of the outline, 1 if missing. The text color or <fgcolor> defines the color to show the inside text. The <font> HTML tag can be used to define the height of the font. For instance the "<font ;31><out 000000><fgcolor=FFFFFF>outlined</fgcolor></out></font>" generates the following picture:

  

• <sha rrggbb;width;offset> ... </sha> define a text with a shadow, where rr/gg/bb represents the red/green/blue values of the shadow color, 808080 if missing as gray, width indicates the size of shadow, 4 if missing, and offset indicates the offset from the origin to display the text's shadow, 2 if missing. The text color or <fgcolor> defines the color to show the inside text. The <font> HTML tag can be used to define the height of the font.  For instance the "<font ;31><sha>shadow</sha></font>" generates the following picture:

  

  or  "<font ;31><sha 404040;5;0><fgcolor=FFFFFF>outline anti-aliasing</fgcolor></sha></font>" gets:
