Consider adding an example for onclick listener

[chungwong]

Given the following Scatter example, it is unclear how to add an onclick listener to the chart.

let mut plot = Plot::new();
let trace = Scatter::new(vec![0, 1, 2], vec![2, 1, 0]);
plot.add_trace(trace);

let layout = plotly::Layout::new().title("Displaying a Chart in Yew");
plot.set_layout(layout);

plotly::bindings::new_plot(id, &plot).await;

In Plotly.js, this can be acheived by capturing the plotly_click event, i.e.

plot.on('plotly_click', function(data) {
  ..
});

Is it supported in plotly.rs?

Hi @chungwong. This is not supported. Would be nice if you could submit a PR with such a feature.

First of all thank you for the marvellous crate!

I would love to have a way to make the browser open a url on clicking on data points (a stacked bar in my case), and was thinking (hoping actually) that that functionality was provided by plotly::layout::ClickMode::Event, and then somehow give it a URL or javascript?

I had been trying to get the plotly_click listener to work in rust/wasm until finally seeing this issue and that it's currently unimplemented :( it would be very highly appreciated if this would be possible.

my current hacky workaround is to use set_onclick on the div containing the plot and then crudely mapping cursor positions, but this only works for me because all i need are the x and y positions and no deeper data.
