高图表：同步不同年份同一天的不规则数据系列

Question

I am comparing temperatures today with the same day last year. I am retrieving the data from a database (via json) and each series has different times (and timestamps). Today's series has datapoints every 10 minutes, last year has data points at 00 and 50 minutes past the hour.

I cannot get both series to plot accurately on the x axis.

I have played about with the pointInterval for last years data to try to get it right but it only ends up looking approximately right.

pointInterval: 3600 * 1000 / 2.05

Is there a way to accurately plot points in both series against the x axis?

Please see jsfiddle

Answer 1

I've managed it. I needed to remove the pointStart and pointInterval from each series, change the year of the 'last year' series to reflect this year and then change to tooltip to show only the hour and minute.
