Serie.LegendFormat Property (ExGraph)

By default, the LegendFormat property is "", which indicates that the name of the serie is shown. The LegendFormat property defines the expression used to customize the label of the series displayed on the legend panel. The Visible property shows or hides the legend. You can use the Def(exSerieLegendFormat) property to define a default LegendFormat that will be automatically assigned to multiple newly created series.

For instance:

"(visible ? ``: ``) + name", shows the name of the serie in bold only if it visible
""`` + name + ` (` + (index + 1) + ')'"", shows the series name followed by its index, displayed in bold
"label + `(` + ((percent) format ``) + `%)`", shows the labels and percent formatted according to the control panel

Currently, the Exontrol's built-in HTML format supports the following HTML tags:

 ...  displays the text in bold.
 ...  displays the text in italics.
 ...  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(AnchorID, Options) event when the user clicks the anchor element. The FormatAnchor property customizes the visual effect for anchor elements.
The ExButton, ExComboBox, ExG2antt, ExGantt, ExGrid, ExHTML, ExLabel, ExList, ExOrgChart, ExplorerTree, ExSchedule, ExSurface, ExSwimlane, ExTree controls support expandable HTML captions feature. The expandable-captions allow you to expand(show)/collapse(hide) different information using <a ;exp=> or <a ;e64=> anchor tags. The exp/e64 field of the anchor stores the HTML line/lines to show once the user clicks/collapses/expands the caption.
- exp, stores the plain text to be shown once the user clicks the anchor, such as <a ;exp=show lines>
- e64, encodes in BASE64 the HTML text to be shown once the user clicks the anchor, such as <a ;e64=gA8ABmABnABjABvABshIAOQAEAAHAAGESikWio+ABzABohp3iELABpABuABljYAgRhAEaFsqAAvAEsjUCmUEg0IhUMhUPjQAAEBA>+</a> that displays show lines- in gray when the user clicks the + anchor. The gA8ABmABnABjABvABshIAOQAEAAHAAGESikWio+ABzABohp3iELABpABuABljYAgRhAEaFsqAAvAEsjUCmUEg0IhUMhUPjQAAEBA string encodes the <fgcolor 808080>show lines<a>-</a></fgcolor> The Decode64Text/Encode64Text methods of the eXPrint can be used to decode/encode e64 fields.
Any ex-HTML caption can be transformed to an expandable-caption, by inserting the anchor ex-HTML tag. For instance, <solidline>Header</solidline> Line1<r><a ;exp=show lines>+</a> Line2 Line3 shows the Header in underlined and bold on the first line and Line1, Line2, Line3 on the rest. The show lines is shown instead of Line1, Line2, Line3 once the user clicks the + sign.
 ...  displays portions of text with a different font and/or different size. For instance, the bit 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, bit displays the bit text using the current font, but with a different size.

<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.
