I want to overlay additional interactive elements on my chart using custom HTML. I want these elements to be positioned exactly as specific data values; similarly, given pixel coordinates within the chart container, I want to be able to determine the X/Y coordinate at that location.
At a minimum, is there any way to determine:
- the x coordinates for the minimum and maximum values on a horizontal axis
- alternatively, the amount of padding to the left of the minimum and right of the maximum
- the y coordinates for the minimum and maximum values on a vertical axis
- alternatively, the amount of padding above the maximum and below the minimum values
I’d love if the chart had a method like “pxToCoord()” that allowed sending in pixel values and getting back chart coordinates, a method like coordToPx()
that allowed sending in X/Y value and getting back pixel offsets within the container. But I’m not sure how these would work with multiple axes.
