Suggestion: Add more options for continuity

[jxxe]

When graphing large datasets, the continuity feature is super helpful! It would be really nice if I could specify a few settings however.

First, I wish I could choose the density of the labels. This could be implemented by adding a parameter for the number of labels I would like to include, and then they would be spaced evenly throughout the data. I could then use data.datasets.values.length to calculate how many labels I would like based on the size of the dataset.

Secondly, but more importantly, I wish I could color or isolate the tick/line for each label. For example:

This chart uses the continuity feature. Everything is working great, except there are lots of ticks on the X axis, one for each datapoint. However, only a few labels are shown. It would be nice if I could remove all of the ticks that do not have their labels shown, or even better, color the ticks that have a label.

I don't feel confident enough in my JavaScript skills to contribute this feature, but is there a callback function I'm missing that would allow me to build it myself and share my solution here?
