Diff Chart- Tooltip Issue

[EdwinMeleth]

In diff chart the labels being shown in tooltip is not correct. The second labels seems to be referencing the second character of the first label. This error is present in the default case (as shown in the screenshot) and also in the case where I am manually naming my labels using -> diff: {
oldData: { opacity: 1, color: 'yellow',
tooltip:{
prefix:'Label 1'
}
},
newData: { opacity: 1, widthFactor: 1,
tooltip:{
prefix:'Label 2'
}
}
} .

Thanks for your report. Definitely a bug. Should be easy to fix.
