Loading
The google.charts.load
package name is "imageareachart"
google . charts . load ( 'current' , { packages : [ 'imageareachart' ]});
The visualization's class name is google.visualization.ImageAreaChart
var visualization = new google . visualization . ImageAreaChart ( container );
Data Format
Each column represents a line in the chart; each entry is the Y axis value at the same X axis point, and the visualization connects them with a straight line, then fills in the area below the line.
Data is processed by column, starting at column zero and increasing. You shoud write the highest lines first, then the lower lines, because if you painted a lower line first, a higher line would paint over and hide any lower lines. Therefore try to make column 1 have higher points than column 2, column 2 higher than column 3, and so on. If you have one or two points higher on a right column than a left column, it might partially obscure the lower line, but it should still be visible.
All data must be numeric type except for the first, which can be either numeric or string. If the first column is a string type, the first column entries will be displayed as labels on the X; if the first column is a number, no X axis labels will be shown. All columns (except the first) must be numbers. There is no limit to the number of columns.
