Charts: clickthrough to filtered doctype or other report

[casesolved-co-uk]

A potential customer has commented that charts are severely limited if clickthroughs are not implemented.

I have looked into the frappe charts library and the click event is accessible with some property data:

frappe/charts#383

fire(this.parent, "data-select", this.getDataPoint());
https://github.com/frappe/charts/blob/f33309601201776c9f724e46badadaeef4663358/src/js/charts/AxisChart.js#L844

lineCompositeChart.parent.addEventListener('data-select', (e) => {
https://github.com/frappe/charts/blob/f33309601201776c9f724e46badadaeef4663358/docs/assets/js/index.js#L20

export function fire(target, type, properties) {
https://github.com/frappe/charts/blob/f33309601201776c9f724e46badadaeef4663358/src/js/utils/dom.js#L114

So I imagine the following needs to happen:

• frappe needs to listen to the relevant chart events to trigger a route change
• all chart datapoints need to be annotated with the correct doctype/report and filters
