p:chart with DateTime axis

I'm trying to create a line chart using the component <p:chart> of the Primefaces 5.1.

And I need the X axis displays the time. Something like this:

enter image description here

But only against documentation of the old version.

I found several things like:

But in version 5.1 there is no such tag <p:lineChart>, and not even the attribute extender="".

I created my chart based on the showcase:

But this example does not help much, because it is only working with date. And to complicate are as String. I need the hours.

I wonder if someone has already created something similar in the newer versions of Primefaces.

EDIT:

Searching a bit more, I found this topic:

I used the example mentioned it, and I could make it work.

What I could see, when it is a DateAxis is required to set the axis.setMax(). At the end looked like this:

enter image description here

It worked as I needed, but two things I did not understand:

First: The reason to be required to set the axis.setMax().

Second: What is this pattern used in axis.setTickFormat("%H:%#M:%S")?

Solution

  • Ok, I think now I found a acceptable solution.

    The initial problem with the chart was axis.setMax().

    And the pattern used in the axis.setTickFormat is: 

    Code    Result                  Description

    The model:

    private void createDateModel() {
    dateModel = new LineChartModel();
    LineChartSeries series1 = new LineChartSeries();
    series1.setLabel("Series 1");
    series1.set("2014-01-01 00:10:50", 51);
    series1.set("2014-01-01 00:10:51", 22);
    series1.set("2014-01-01 00:10:52", 65);
    series1.set("2014-01-01 00:10:53", 35);
    dateModel.addSeries(series1);
    dateModel.getAxis(AxisType.Y).setLabel("Values");
    DateAxis axis = new DateAxis("Dates");
    axis.setTickAngle(-50);
    axis.setMax("2014-01-01 00:10:56");
    axis.setTickFormat("%H:%#M:%S");
    dateModel.getAxes().put(AxisType.X, axis);
}

    And the chart:

    <p:chart type="line" model="#{controller.dateModel}" />
