I'm implementing jQuery Sparklines plugin for a web app I'm developing. I want to add tags to the pie chart values so when you hover over that specific chart you will se "Automotive (25%)" instead of the default int value "1 (25%)".
Any ideas on how this could be done?
Here is the code I have:
$(function(){
var myvalues = [10,8,5,7,4,4,1];
$('#sparkline').sparkline(myvalues, {
type: 'pie',
width: '200px',
height: '200px',
sliceColors: ['#5d3092', '#4dc9ec', '#9de49d', '#9074b1', '#66aa00', '#dd4477', '#0099c6', '#990099'],
borderWidth: 7,
borderColor: '#f5f5f5'
});
});
Thanks!
A better alternative to using tooltipPrefix or writing your own formatter is to use tooltipFormat and tooltipValueLookups instead to map the index in your array of values to a name:
$(function() {
var myvalues = [10,8,5,7,4,4,1];
$('#sparkline').sparkline(myvalues, {
type: 'pie',
width: '200px',
height: '200px',
sliceColors: ['#5d3092', '#4dc9ec', '#9de49d', '#9074b1', '#66aa00', '#dd4477', '#0099c6', '#990099'],
borderWidth: 7,
borderColor: '#f5f5f5',
tooltipFormat: '<span style="color: {{color}}">●</span> {{offset:names}} ({{percent.1}}%)',
tooltipValueLookups: {
names: {
0: 'Automotive',
1: 'Locomotive',
2: 'Unmotivated',
3: 'Three',
4: 'Four',
5: 'Five'
// Add more here
}
}
});
});
Here's a link to the Sparkline docs for the above methods: http://omnipotent.net/jquery.sparkline/#tooltips
