[Bug report] Tooltip Bug for Mixed chart type candlestick & line

[rashearth]

Hi, thanks for the migration for the chart.js 3.0 . I just found some bugs written in the title of this report.

please kindly check it through.

[what i done] I made a simple mixed chart of candlestick and line chart

[bugs]

Here, the tooltips have some issue when pointing the mouse to the line chart.(it seems to be OK in the candlestick)

there is many errors occuring, and the tooltip freezes+ wont show the right data. I assume that it has some compatibile issue with line chart {x: , y: ,} format and candlestick { t:,o:,h:,l:,c,} format

[code] Here it is!

I'm not seeing any errors in the developer console. I did make some changes recently and you seem to be linking directly to https://www.chartjs.org/chartjs-chart-financial/chartjs-chart-financial.js so perhaps it's been fixed

Yep I've hit the same issue. Yet another breaking change to v3.0.0, yay. Fine with beta.6, errors with beta.7

I stuck a breakpoint on the "if", but we don't seem to enter this function in beta.6 (and beta.7 we can see that Chart.Chart.defaults.interaction.callbacks is null:

if (!isNullOrUndef(point.y)) {
    return Chart.Chart.defaults.interaction.callbacks.label(ctx);
}

Same here.
