dataPoints: Array

It represents collection of dataPoints inside dataSeries .



dataPoint: Object

Each value that has to be plotted on the chart is referred to as a dataPoint.



Notes
  • 3 commonly used dataPoint properties that you should remember are x, y and label
  • Some attributes like indexLabel, tooltipContent etc. comes both in dataSeries and dataPoint, in such case values set at dataPoint is given priority over dataSeries. 


var  chart =  new  CanvasJS.Chart("container",
{
 .
 .
 data:[
 { //dataSeries
 .
 .
 dataPoints : [ // values go here
  .
  .
  ],
 },


});
chart.render();

  4. Is there a way to show the y value of a column chart on each column and not only on mouse hover as a tool tip?

  5. is there a way to get the actual canvas x/y position of a data point?
    also, how could i draw a section of a graph colored about the x or y axis? or about multiple (let’s say i want to create a rectangle over a certain x/y range of a line chart).
    thanks

  7. How can I initialize datapoints array dynamically? instead of say, 10 points I want to add as many points as available in a javascript array;
