Hi,

 I'm trying to create a chart that shows the performance of a machine.

The datasource is an XML with N records containing a value and the acquisition date ( by minutes ). This XML can contain up to 1440 records ( 24Hours )

When the chart renders I would like to see as category Axis labels, only the hours ( see Result.PNG )

 I tried to do so:

 categoryAxis: {
                    field: "end_time",
                    baseUnit: "minutes",
                    minorUnit: 60,
                    labels: {
                        format: 'hh tt'
                    }
                }

 but is not working ( WrongResult.PNG ) Do you have any suggestions?

Thanks

Luca

Hello Luca,

The first thing we have to do to handle this scenario is to set the step property of the labels of the category axis so they don't get overlapped. You would want this step property to be equal to 60 to show only one label per hour. Try this and let's see how it looks:

categoryAxis: {
    field: "end_time",
    baseUnit: "minutes",
    minorUnit: 60,
    labels: {
        step: 60,
        format: 'hh tt'
    }
}

Tell us how it looks, or better yet, create a Kendo UI Dojo that replicates your scenario so we can edit it for ourselves, and we'll take it from there.
