ChartDataJson

ChartDataJson

This is a more complex method to configure the chart than chartData but offers a lot more possibilities.

See a List of properties, you can set per line, or bar:

[{
    "data": "OverallPrice", //the column to take for the line values from the sub dataset
    "color": "red", //line color
    "fill": "false" //do not fill the gap to the bottom line
},
{
    "data": "OwnPrice", //the column to take for the line values from the sub dataset
    "color": "blue",
    "backgroundColor": "yellow", //background color for the gap or the bar, in case of a bar chart
    "fill": "0" //means you fill the gab to the first (0) line. 
}]
