A time chart can display graphs of series as lines or columns. The horizontal axis (x-axis) always displays time and the vertical axis (y-axis) represents the value of the series at each point in time.
A time chart only displays series with the same frequency, i.e. the same number of observations per year. If you work with multiple series that have different original frequencies, their frequencies will be harmonized to a common one.
- Main title
- Graph area
- Value axis (y-axis)
- Source text
- Chart background
- Time axis (x-axis)
To edit any one of these components, click on it, and the available options will appear at the top of the window, under the presentation properties tab.
Time axis settings
Clicking on the x-axis gives you a variety of options under presentation properties. Here are a few that are specific to time charts:
For the chart elements: Title, Axis, Legend and Copyright/Source, controls the distance between the element and the next element in the direction of the chart.
Example: If the legend is at the bottom of the chart the Distance setting for the legend is given relative to the x-axis labels. If the legend is at the top the distance is given relative to the top of the graph area.
For the axes, the setting controls the distance between the tick marks (or axis if there are no tick marks) and the label texts.
This controls the space between the rows in the case the labels on the axis are written on two rows.
In the scale group you can adjust the time range displayed on the axis by specifying start and end dates.
End margin specifies the percentage of the chart that will be visible between the end of the graph and the y-axis.
If you select start at shortest or end at shortest, the display range of the chart will be adjusted based on the start or end date of the shortest series (if the chart includes more than one series).
Here, you can edit the way the scale is labelled.
The automatic setting labels the scale with the frequency that allows for the best view. Unchecking it will allow you to use the manual step option, where you can specify another frequency for the axis labels.
Detail limit allows you to choose a date format for the labels.
When Include century is unchecked, it’ll display only the last two digits of each year.
Allow month initials will allow the application to display only the first letter of each month when the 3-letter abbreviation doesn’t fit.
Uncheck Show labels if you want to hide the axis labels altogether.
This group of settings manages the distance between elements on the chart. Indentation defines the minimum distance from the leftmost/rightmost side of the chart and the left/right side of the graph area.
