Chart Features

The DateTime Axis maps time values evenly between a minimum and maximum value along a chart axis. By default, it determines minimum, maximum, interval and intervalType values from the charting data to fit all of the chart elements on the screen. You can also explicitly set specific values for these properties.

The DateTime Axis chooses the most reasonable intervals to mark the axis by examining the range between the minimum and maximum values of the axis.

In this sample the minimum, maximum, interval and intervalType are set explicitly.

For detailed implementation, please take a look at the HTML code tab.
