bar chart with skipNull crashes if there are datasets of different lengths

[TheRealSyler]

Expected behavior

You should be able to have the skipNull option enabled and use the datasets in the example below.

const datasets = [
    { data: [1, 2] },
    { data: [1, 2, 3] },
]

Current behavior

It Crashes here, because item.controller.getParsed(dataIndex) returns undefined, you cannot use item.controller._cachedMeta.vScale.axis to access undefined.

Reproducible sample

Optional extra steps/info to reproduce

var ctx = document.getElementById("myChart");

var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
    labels: [ 1,2 ],
    datasets: [
      { data: [1, 2] },
      { data: [1, 2] }, // ,3
    ]
    },
    options: {
       responsive: true,
       skipNull: true,
    }
});

Possible solution

Change this

From:

const val = item.controller.getParsed(dataIndex)[item.controller._cachedMeta.vScale.axis];

To:

const parsed = item.controller.getParsed(dataIndex)
const val = parsed && parsed[item.controller._cachedMeta.vScale.axis];
