Grapher can create a graph with data based on dates, times, or dates and times.
When data are stored in the worksheet in date/time format, Grapher will automatically recognize the format and create the axis displaying the dates in most cases. Different date/time formats can be used.
The dates in the left column are in MM/dd/yy hh:mm AM/PM format.
To create a graph from date/time data, click the Graphs | Create | <graph category> | <plot type> command. Select the data file and click Open. The appropriate axis will automatically be in date/time format.
The X axis is automatically displayed in date/time format.
If the date/time values are formatted with a custom date/time format that is not recognized as date/time by Grapher:
- Select the axis.
- Click on the Labels tab in the Property Manager.
- Check the box in the General section next to Use date/time format.
- To format the date/time labels, click the Select button next to Major label date/time format, choose the desired formatting in the Date/Time Format Builder dialog, and click OK.
For more information on date/time axis labels, see the Date/Time Axes training video.
