18.10.2017 08:40
18.10.2017 09:15
My period: 15 min
How I can see data on 18.10.2017 08:40?
Mydata:
[
{
"column-1": 8,
"column-2": 5,
"date": "2014-03-01 08:00"
},
{
"column-1": 6,
"column-2": 7,
"date": "2014-03-01 08:15"
},
{
"column-1": 1,
"column-2": 3,

},
{

},
{
"column-1": 6,
"column-2": 8,

Answer 1

Make sure your minPeriod is set to the lowest period that can display your data. If your data isn't always in 15 minute increments, then use "mm" instead of "15mm". Since you have gaps, you'll also want to set the gapPeriod to a value that best represents where you want the gap to appear - if your data is usually within 15 minutes, then set it to 15.1:
graphs: [
{
// ...
connect: false,
gapPeriod: 15.1,
// ...
},{
// ...
connect: false,
gapPeriod: 15.1,
// ...
}
],
// ...
categoryAxis: {
parseDates: true,
minPeriod: "mm"
}
