如何向 Dojox 图表添加自定义工具提示？
假设我有这个：
var chart1 = new dojox.charting.Chart2D("traffic");
chart1.addPlot("default", {type: "Columns", gap: "15"});
chart1.addAxis("x", {minorTicks: false, font: "normal normal bold 9pt Arial",
labels: [{value: 1, text: 'Monday'},{value: 2, text: 'Tuesday'},{value: 3, text: 'Wednesday'},{value: 4, text: 'Thursday'},{value: 5, text: 'Friday'},{value: 6, text: 'Saturday'},{value: 7, text: 'Sunday'}]});
chart1.addAxis("y", {vertical: true, minorTicks: false, min: 0, font: "normal normal bold 12pt Arial"});
chart1.addSeries("Series 1", [<?php echo $trafficseries; ?>]);
chart1.setTheme(dojox.charting.themes.PlotKit.blue);
chart1.addPlot("Grid", {
type: "Grid",
hAxis: "x",
vAxis: "y",
hMajorLines: true,
hMinorLines: false,
vMajorLines: false,
vMinorLines: false
});
var anim_t = new dojox.charting.action2d.Tooltip(chart1, "default");
chart1.render();
我如何更改该工具提示以说出我需要它说的内容？我需要将 X 数据放在那里。
Say I have this:
var chart1 = new dojox.charting.Chart2D("traffic");
chart1.addPlot("default", {type: "Columns", gap: "15"});
chart1.addAxis("x", {minorTicks: false, font: "normal normal bold 9pt Arial",
labels: [{value: 1, text: 'Monday'},{value: 2, text: 'Tuesday'},{value: 3, text: 'Wednesday'},{value: 4, text: 'Thursday'},{value: 5, text: 'Friday'},{value: 6, text: 'Saturday'},{value: 7, text: 'Sunday'}]});
chart1.addAxis("y", {vertical: true, minorTicks: false, min: 0, font: "normal normal bold 12pt Arial"});
chart1.addSeries("Series 1", [<?php echo $trafficseries; ?>]);
chart1.setTheme(dojox.charting.themes.PlotKit.blue);
chart1.addPlot("Grid", {
type: "Grid",
hAxis: "x",
vAxis: "y",
hMajorLines: true,
hMinorLines: false,
vMajorLines: false,
vMinorLines: false
});
var anim_t = new dojox.charting.action2d.Tooltip(chart1, "default");
chart1.render();
How would I change that tooltip to say what I need it to say? I need to put X data there.

这可以通过向系列数据添加工具提示值来完成：
Chart1.addSeries("系列 1", [{x:1,y:4,tooltip:"值为 1"},{x:2,y:6,tooltip:"值为 2"}]);
This can be done by adding a tooltip value to the series data:
chart1.addSeries("Series 1", [{x:1,y:4,tooltip:"Value is 1"},{x:2,y:6,tooltip:"Value is 2"}]);
您可以，new Tooltip(chart1,"default",{text: function(o){return oy + "M/s";}});,自定义文本值设置函数。
You can,new Tooltip(chart1,"default",{text: function(o){return o.y + "M/s";}});,custom text value set a function.
