Methods

createFunction

▸ createFunction(): Function

Creates a custom function used to provide data and settings for SparklineEx.

Returns

Function

The created custom function.

Inherited from

SparklineEx.createFunction

fromJSON

▸ fromJSON(settings): void

Loads the object state from the specified JSON string.

example

window.MySparklineEx = function(color) {
    GC.Spread.Sheets.Sparklines.SparklineEx.apply(this, arguments);
    this.typeName = 'MySparklineEx';
    this.color = color;
}
MySparklineEx.prototype = new GC.Spread.Sheets.Sparklines.SparklineEx();
MySparklineEx.prototype.createFunction = function () {
    var func = new GC.Spread.CalcEngine.Functions.Function('CIRCLE', 0, 0);
    func.evaluate = function (args) {
          return {};
    };
    return func;
 };
MySparklineEx.prototype.paint = function (context, value, x, y, width, height) {
     context.beginPath();
     context.arc(x + width / 2, y + height / 2, (Math.min(width, height) - 6) / 2, 0, Math.PI * 2);
     context.strokeStyle = this.color;
     context.stroke();
};
let sparkline = new MySparklineEx("green");
sparkline.fromJSON({ color: "red", typeName: "MySparklineEx" });
spread.addSparklineEx(sparkline);
sheet.setFormula(3,3,"=CIRCLE()");
