Updating from, to on mount renders partial histogram bars

[hsks]

Steps to reproduce

1. Update the from and to range of the histogram using the update() method once the histogram is mounted.
2. Once in a while, refresh the page/re-mount the component.

Observation
The histogram is partially rendered.

I think the canvas is in the midst of painting the graph while an update is triggered.
The extent to which the bars are rendered depends on how quick the component renders. If the component is moderately light, the partial rendering of the histogram is visible as shown:

This is taken from the example histogram provided in the source directory.

A possible workaround is an explicit wait for the rendering of the histogram to complete, would be great if there could be an event raised once the histogram has completed rendering.

I noticed I reproduce this behavior if I call update() inside of this.$nextTick as well.

I am just attempting to set the from/to programatically.
