First of all congratulations on this amazing library, I’ve been using it on all my personal projects and I just can’t get enough of it!
Second I would like to know what parameters I have access in the onclick function in a Data Point? Is it only the x and y values? Can I get somehow the label value for the Data Point to pass as parameter to a JS function?
You can access all properties of dataPoint/dataSeries including label. Upon any mouse event you get dataSeries and dataPoint inside the parameter e – which is passed to the event handler function. Once you have the handle to dataPoint, you can access all the properties inside dataPoint
