(scaled) y value for given x value

Question

I'm modifying some examples [1][2] to draw a line on the canvas. For the end-point I have calculated a data value but now I want to calculate the y value on the canvas. In the examples I found

this.chart.chart.scale.getPixelForValue()

which seems deprecated in chart.js 2.6

// Used to get data value locations.  Value can either be an index or a numerical value
getPixelForValue: helpers.noop,

The first example uses

this.calculatePointY()

but that doesn't help me either.

What would I use instead?

Answer 1

For ChartJS - version 2.6, you should use the following ...

chart.scales['y-axis-0'].getPixelForValue(<value>);
