tôi đang tìm kiếm cùng một câu hỏi, tiếc là không có câu trả lời nào. Các giải pháp xấu xí mà tôi đến với là, sửa đổi jqplot.highlighter.js để có được những gì tôi muốn. Dưới đây là như thế nào, tôi thực hiện điều này,
Khai xAxisFormatString và yAxisFormatString tính
// prop: xAxisFormatString
// If this is provided then it will override the axesformatter format string
this.xAxisFormatString = '';
// prop: xAxisFormatString
// If this is provided then it will override the axesformatter format string
this.yAxisFormatString = '';
Sau đó, ở phương pháp showtooltip sử dụng này thay vì chuỗi định dạng trục
var xfstr = series._xaxis._ticks[0].formatString;
if('' != hl.xAxisFormatString)
xfstr = hl.xAxisFormatString;
var yfstr = series._yaxis._ticks[0].formatString;
if('' != hl.yAxisFormatString)
yfstr = hl.yAxisFormatString;
Khi gọi đồ thị,
highlighter: {
show: true,
useAxesFormatters: true,
xAxisFormatString: '%m-%Y',
formatString: 'hi - %s',
sizeAdjust: 7.5
},
Tôi có useAxesFormatters đúng bởi vì tôi không muốn để gây rối với tooltipformatstring. Tôi không sao để sử dụng cùng một trình định dạng nhưng tôi muốn ghi đè định dạng chuỗi. theo cách này tôi đã làm việc.
Đây là jqplot.highlighter.js hoàn

/**
* Class: $.jqplot.Highlighter
* Plugin which will highlight data points when they are moused over.
*
* To use this plugin, include the js
* file in your source:
*
* > <script type="text/javascript" src="plugins/jqplot.highlighter.js"></script>
*
* A tooltip providing information about the data point is enabled by default.
* To disable the tooltip, set "showTooltip" to false.
*
* You can control what data is displayed in the tooltip with various
* options. The "tooltipAxes" option controls wether the x, y or both
* data values are displayed.
*
* Some chart types (e.g. hi-low-close) have more than one y value per
* data point. To display the additional values in the tooltip, set the
* "yvalues" option to the desired number of y values present (3 for a hlc chart).
*
* By default, data values will be formatted with the same formatting
* specifiers as used to format the axis ticks. A custom format code
* can be supplied with the tooltipFormatString option. This will apply
* to all values in the tooltip.
*
* For more complete control, the "formatString" option can be set. This
* Allows conplete control over tooltip formatting. Values are passed to
* the format string in an order determined by the "tooltipAxes" and "yvalues"
* options. So, if you have a hi-low-close chart and you just want to display
* the hi-low-close values in the tooltip, you could set a formatString like:
*
* > highlighter: {
* > tooltipAxes: 'y',
* > yvalues: 3,
* > formatString:'<table class="jqplot-highlighter">
* > <tr><td>hi:</td><td>%s</td></tr>
* > <tr><td>low:</td><td>%s</td></tr>
* > <tr><td>close:</td><td>%s</td></tr></table>'
* > }
