Perhaps a mistake but sample chart doesn't work... at this moment
This part seems to be a mistake, property of the chart are mixed with category items, but also removing it it doesn't render.
Can you show me something of working?
{
"category": [
{ "label": "Mon" },
{ "label": "Tue" },
{ "label": "Wed" },
{
"vline": "true",
"lineposition": "0",
"color": "#6baa01",
"labelHAlign": "center",
"labelPosition": "0",
"label": "National holiday",
"dashed":"1"
},
{ "label": "Thu" },
{ "label": "Fri" },
{ "label": "Sat" },
{ "label": "Sun" }
