For example:</p> <p>In require statment, add "dojox/charting/action2d/Tooltip" In your chart data add 'tooltip' with text to display on mouse over</p> <p>JSON chart data:</p> <pre><code>var chartdata = [{x: 8,y:"0",tooltip:"What to show during mouse over"}]; </code></pre> <p>JS code to use tooltip in your chart data:</p> <pre><code>// Create the tooltip which will show during mouse over var tip = new Tooltip(chart,"default"); // Render the chart! chart.render(); </code></pre> <p>That is all you need...Not sure about your second question...</p> <p>This is easy stuff, visit this charting example page: <a href="http://dojotoolkit.org/documentation/tutorials/1.8/charting/" rel="nofollow">http://dojotoolkit.org/documentation/tutorials/1.8/charting/</a></p> <p>Using your existing example, here is how you add mouse over:</p> <pre><code>require(["dojo/ready", "dojox/charting/Chart2D","dojox/charting/themes/Claro","dojox/charting/action2d/Tooltip",], function(ready, Chart,ClaroTheme,Tooltip) { ready(function() { var mychart = Chart("mychart"); mychart.title = "My Chart"; mychart.titleFont = "tahoma"; mychart.addPlot("line_plot", { type: "Lines", lines: true, areas: false, markers: true }); mychart.addPlot("column_plot", { type: "Columns", lines: true, areas: false, markers: true }); mychart.addAxis("x", { vertical: false }); mychart.addAxis("y", { vertical: true }); var column_data = [{y:1,x:1,tooltip: "column 1"}, {y: 3,x:2,tooltip: "column 2"}, {y:5,x:3,tooltip: "column 3"}, {y:2,x:4,tooltip: "column 4"}, {y:6,x:5,tooltip: "columnt 5"}, {y:1,x:6,tooltip: "column 6"}, {y:0,x:7,tooltip: "column 7"}, {y:4,x:8,tooltip: "column 8"}, {y:6,x:9,tooltip: "column 9"}, {y:4,x:10,tooltip: "column 10"}, {y:1,x:11,tooltip: "column 11"}]; var bar_data = [{y:1,x:1,tooltip: "bar 1"}, {y: 3,x:2,tooltip: "bar 2"}, {y:5,x:3,tooltip: "bar 3"}, {y:2,x:4,tooltip: "bar 4"}, {y:6,x:5,tooltip: "bar 5"}, {y:1,x:6,tooltip: "bar 6"}, {y:0,x:7,tooltip: "bar 7"}, {y:4,x:8,tooltip: "bar 8"}, {y:6,x:9,tooltip: "bar 9"}, {y:4,x:10,tooltip: "bar 10"}, {y:1,x:11,tooltip: "bar 11"}]; mychart.addSeries("line_series", bar_data, { plot: "line_plot" }); mychart.addSeries("column_series", column_data, { plot: "column_plot" }); mychart.setTheme(ClaroTheme); var tip = new Tooltip(mychart,"line_plot"); var tip1 = new Tooltip(mychart,"column_plot"); mychart.render(); }); }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
