This is a plugin for Google Chart API.
- Supports pie charts, bar charts, line charts, venn diagrams, and scatter plots
- Seeks to fully implement Google's spec, http://code.google.com/apis/chart/
- Builder to create Google Chart URLs in domain or service layer.
- Recently added: Maps, Text Data Encoding with Scaling.
Setup
To install
grails install-plugin google-chart
After install test out the charts by going to this page:
http://localhost:8080/app/plugins/google-chart-<version>/index.gsp
Conventions
Generally if the required attribute can take more than 4 objects/parameters, it is expected to be passed as an ArrayList.
For example, assuming values3, colors, and labels are ArrayLists, this would be the tag to make a pie chart.
<g:pieChart title='Sample Pie Chart' colors="${colors}" labels="${labels}" fill="${'bg,s,efefef'}" dataType='text' data='${values3}' />
Builder Example
def chart = new GoogleChartBuilder()
result = chart.lineChart{
size(w:300, h:200)
title{
row('Joy vs. Pain')
}
data(encoding:'extended'){
dataSet([1,18,200,87,1090,44,3999])
dataSet([88,900,77,1,2998,4])
}
colors{
color('66CC00')
color('3399ff')
}
lineStyle(line1:[1,6,3])
legend{
label('Joy')
label('Pain')
}
axis(left:(1..5).toList(), bottom:[])
backgrounds{
background{
solid(color:'999999')
}
area{
gradient(angle:45, start:'CCCCCC', end:'999999')
}
}
markers{
rangeMarker(type:'horizontal', color:'FF0000', start:0.75, end:0.25)
rangeMarker(type:'vertical', color:'0000cc', start:0.7, end:0.71)
}
}
Roadmap
- Possibly a domain object
