StripLines – strange output using dates

[ChrisEvans_UK]

Hi all

I have been trying to set up strip lines on my chart. The x axis has datetime fields, with all dates in July (month 7) of 2019, however I need to set up the striplines using the same year, day, hour, minute HOWEVER I need to use June (month 6)!!

What am I doing wrong?

My jsfiddle demonstrates this:

Can anyone help?

A second point, I seem to have to include the following code just to get the chart to work in the first place (before I try adding striplines):

for (var i = 0; i < rawData.length; i++) {
rawData[i][“x”] = new Date(rawData[i][“x”]);
}

Do I really need that?

Any help is greatly appreciated.

Regards
Chris

Chris,

In JavaScript month index starts from 0(January) and ends at 11(December). For more information please refer to this StackOverflow page.

X values can either be number or date-object. In your case, to make it date-object this loop would be required.
