Test for Option useVal and percentVal

For example, if you want to use number value, then you need only "useVal": "yes". in many chart, non percent value are default.

you want to use percentage value for the bar chart, then need both "percentVal": "yes", and "useVal": "yes". like following code. ( default value of stacked% and pie are percent )

<canvas id="hoge"></canvas>
<script>
var conf = {
    "title": "useVal: yes for bar",
    "type": "line",
    "width": 400,
    "height": 320,
    "useVal": "yes"
    
};
var data = [
    ["月",1,2,3,4,5,6,7,8],
    ["ウーロン",20,23,12,20,42,50,43,56],
    ["コーヒー",52,50,44,50,60,55,68,80]
];
ccchart
  .init('hoge0-1', {
    "config": conf
    "data": data
  })
</script>
<canvas id="hoge"></canvas>
<script>
var conf = {
    "title": "use percentage value",
    "type": "line",
    "width": 400,
    "height": 320,
    "useVal": "yes",
    "percentVal": "yes"
    
};
var data = [
    ["月",1,2,3,4,5,6,7,8],
    ["ウーロン",20,23,12,20,42,50,43,56],
    ["コーヒー",52,50,44,50,60,55,68,80]
];
ccchart
  .init('hoge0-2', {
    "config": conf
    "data": data
