How to use fixed Y axis 0-100%

[wep]

Hi, I have data that can be only 0 to 100. I would like the Y axis to always show 0-100 regardless of highest data point. Is this possible?

Thanks, Bill

@wep,

You can specify the minimum and maximum permitted values by setting minimum and maximum property of axisY to 0 and 100 respectively.

If this is not what you are looking for can you please create a jsfiddle so that we can look into your code and help you out better.

i have data like:

dataPoints: [
{ x: 10, y: 150 },
{ x: 20, y: 400},
{ x: 30, y: 500 },
{ x: 40, y: 2000 },
{ x: 50, y: 814 },
{ x: 60, y: 68 },
{ x: 70, y: 28 },
{ x: 80, y: 34 },
{ x: 90, y: 14}
]

I want to show axisY to 100%. is there any solution.

@saqib,

Can you kindly brief us more about your scenario and what is the reference value for 100% (100% of what value) so that we can understand your requirement better and help you out?

I want to Y value to counted as 100%.
Actually my Data looks like this:

dataPoints: [
  { x: new Date(), y: 150 },
  { x: new Date(), y: 400},
  { x: new Date(), y: 500 },
  { x: new Date(), y: 2000 },
]

`axisY: {
suffix: “%” // this should be calculated to 100% of Y values.
},`

One more thing!!
What if i have More then 1 Line. how can i calculate 100% for Multi data (multiple objects as dataPoints).
in the blow data i have max point in 2 object and it can be in any object as it is multi line chart. how can i calculate in that scenario.

data: [              
      {
        // Change type to "doughnut", "line", "splineArea", etc.
        type: "spline",
        dataPoints: [
          { x: 10, y: 150 },
          { x: 20, y: 400 },
          { x: 30, y: 500 },
          { x: 40, y: 2000 },
          { x: 50, y: 814 },
          { x: 60, y: 68 },
          { x: 70, y: 28 },
          { x: 80, y: 34 },
          { x: 90, y: 14 }
        ]
      },
      {
        type: "spline",
        dataPoints: [
          { x: 10, y: 150 },
          { x: 20, y: 400 },
          { x: 30, y: 800 },
          { x: 40, y: 1500 },
          { x: 50, y: 814 },
          { x: 60, y: 68 },
          { x: 70, y: 3000 },
          { x: 80, y: 34 },
          { x: 90, y: 14 }
        ]
      }
    ]

Got the solution with some changes in for Loop.

 let a = [];
  chart.options.data.forEach((val, i)=>{
    //alert(JSON.stringify(val), i);
    val.dataPoints.forEach((val2)=>{
      a.push(val2.y)
    })
  })
  maxY = Math.max(...a);
  console.log(maxY, a)
