Axis Options
|
|
Right Axis (--right-axis <scale:shift>)
|
|
A second axis will be drawn to the right of the graph. It is tied to the left axis via the scale and shift parameters.
|
|
Right Axis Label (--right-axis-label <string>)
|
|
The label for the right axis.
|
|
Right Axis Format (--right-axis-format <format>)
|
|
By default, the format of the axis labels gets determined automatically. If you want to do this yourself, use this option with the same %lf arguments you know from the PRINT and GPRINT commands.
|
|
Right Axis Formatter (--right-axis-formatter <formatname>)
|
|
When you setup the right axis labeling, apply a rule to the data format. Supported formats include "numeric" where data is treated as numeric, "timestamp" where values are interpreted as UNIX timestamps (number of seconds since January 1970) and expressed using strftime format (default is "%Y-%m-%d %H:%M:%S"). See also --units-length and --right-axis-format. Finally "duration" where values are interpreted as duration in milliseconds. Formatting follows the rules of valstrfduration qualified PRINT/GPRINT.
|
|
Left Axis Formatter (--left-axis-formatter <formatname>)
|
|
When you setup the left axis labeling, apply a rule to the data format. Supported formats include "numeric" where data is treated as numeric, "timestamp" where values are interpreted as UNIX timestamps (number of seconds since January 1970) and expressed using strftime format (default is "%Y-%m-%d %H:%M:%S"). See also --units-length. Finally "duration" where values are interpreted as duration in milliseconds. Formatting follows the rules of valstrfduration qualified PRINT/GPRINT.

Legend Options
|
|
Auto Padding
|
|
Pad text so that legend and graph data always line up. Note: this could cause graphs to take longer to render because of the larger overhead. Also Auto Padding may not be accurate on all types of graphs, consistent labeling usually helps.
|
|
Dynamic Labels (--dynamic-labels)
|
|
Draw line markers as a line.
|
|
Force Rules Legend (--force-rules-legend)
|
|
Force the generation of HRULE and VRULE legends.
|
|
Tab Width (--tabwidth <pixels>)
|
|
By default the tab-width is 40 pixels, use this option to change it.
