Use the ToolTip property to assign a tooltip to a node. Use the ToolTipTitle property to specify the title of the tooltip window. The tooltip shows up when the cursor hovers the node. The ToolTip property supports built-in HTML tags like the Caption property does. The ToolTipPopDelay property specifies the period in ms of time the ToolTip remains visible if the mouse pointer is stationary within a control. Use the ToolTipWidth property to specify the width of the tooltip window. The ToolTipDelay property specifies the time in ms that passes before the ToolTip appears. Use the Root property to get the root node. Use the <img> HTML tag to insert icons inside the node's caption. Use the ToolTipFont property to assign a font for the control's tooltip. Use the Background(exToolTipAppearance) property indicates the visual appearance of the borders of the tooltips. Use the Background(exToolTipBackColor) property indicates the tooltip's background color. Use the Background(exToolTipForeColor) property indicates the tooltip's foreground color.

The ToolTip property supports built-in HTML format like listed:

• <b>  bold </b>
• <u> underline </u>
• <s> strikeout </s>
• <i> italic </i>
• <fgcolor = FF0000> fgcolor </fgcolor>
• <bgcolor = FF0000> bgcolor </bgcolor>
• <br> breaks the line
• <solidline> draws a solid line
• <dotline> draws a dotted line
• <upline> draws the line to the top of the text line
• <r> aligns the rest of the text line to the right side.
• <img>number[:width]</img> inserts an icon inside the cell's caption. The number indicates the index of the icon being inserted. 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 being 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.
• <font face;size>text </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.

The following VB sample adds a node with a tooltip:

With ChartView1 .BackColor = vbWhite With .Nodes With .Add("<r><dotline><b><fgcolor=0000FF>Andrew Fuller</fgcolor></b><br><solidline><b>Title</b>:<r><fgcolor=FF0000>Vice President Sales</fgcolor><br>USA, Tacoma, WA, 98401, 908 W. Capital Way<br><dotline><upline><b>Phone:</b><r>(206) 555-9482", "nancy", , 1, "c:\temp\sample\andrew.gif") .Position = 0 .BackColor = vbWhite .ToolTip = "<dotline><r><b><fgcolor=0000FF>Andrew Fuller</fgcolor></b><br>Andrew received his BTS commercial in 1974 and a Ph.D. in international marketing from the University of Dallas in 1981. He is fluent in French and Italian and reads German. He joined the company as a sales representative, was promoted to sales manager." .ToolTipTitle = "Information" End With End With End With

The following C++ sample assigns a tooltip to the root node:

CNode node = m_chartview.GetRoot(); node.SetToolTip( "<dotline><r><b><fgcolor=0000FF>Andrew Fuller</fgcolor></b><br>Andrew received his BTS commercial in 1974 and a Ph.D. in international marketing from the University of Dallas in 1981. He is fluent in French and Italian and reads German. He joined the company as a sales representative, was promoted to sales manager." ); node.SetToolTipTitle( "Information" );

The following VB.NET sample assigns a tooltip to the root node:

With AxChartView1.Root .ToolTip = "<dotline><r><b><fgcolor=0000FF>Andrew Fuller</fgcolor></b><br>Andrew received his BTS commercial in 1974 and a Ph.D. in international marketing from the University of Dallas in 1981. He is fluent in French and Italian and reads German. He joined the company as a sales representative, was promoted to sales manager." .ToolTipTitle = "Information" End With

The following C# sample assigns a tooltip to the root node:

EXORGCHARTLib.Node node = axChartView1.Root; node.ToolTip = "<dotline><r><b><fgcolor=0000FF>Andrew Fuller</fgcolor></b><br>Andrew received his BTS commercial in 1974 and a Ph.D. in international marketing from the University of Dallas in 1981. He is fluent in French and Italian and reads German. He joined the company as a sales representative, was promoted to sales manager."; node.ToolTipTitle = "Information";

The following VFP sample assigns a tooltip to the root node:

With thisform.ChartView1.Root local s s = "<dotline><r><b><fgcolor=0000FF>Andrew Fuller</fgcolor></b><br>Andrew received his BTS commercial in 1974 and a Ph.D. in international marketi" s = s + "ng from the University of Dallas in 1981. He is fluent in French and Italian and reads German. He joined the company as a sales representati" .ToolTip = s + "ve, was promoted to sales manager." .ToolTipTitle = "Information" EndWith
