I have this example from chart.js
docs :
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ['Item 1', 'Item 2', 'Item 3'],
datasets: [
{
type: 'bar',
label: 'Bar Component',
data: [10, 20, 30],
},
{
type: 'line',
label: 'Line Component',
data: [30, 20, 10],
}
]
}
});
It works fine. However, my intention is to change the type dynamically.
I am aware that there is getDatasetMeta()
method, that you can apply to your chart instance, and if I output the result it returns to the console I get something like this:
{
bar: true,
controller: ChartElement,
data: Array[...],
dataset: null,
hidden: false,
type: 'bar',
...
}
I can control the appearance of a certain dataset via hidden
property, though if I change type
to line
and invoke update()
it won't re-render.
So, is there a way to dynamically change dataset type?
Found a workaround here: Chart.js: Dynamic Changing of Chart Type (Line to Bar as Example)
Sad that it's not yet supported officially.
