Interval Chart (JFreeChart)
This view shows an interval chart visualizing the intervals
of the input table. There each row is treated as an interval in which
the "Label" specifies the name and the "Start" and "End" column specify
the start and end points of the interval. The order of the labels on the
y-axis is taken from the order of the occurrences in the data table.
Highlighting is not supported. For general settings of the generated
image, see the "General Plot Options" Tab.
Dialog Options
Interval Chart Options
- Label
- Column containing the name of interval
- Start
- Column containing the start point of interval
- End
- Column containing the end point of the interval
- Focus on earliest and latest interval
- If activated the
x-axis begins with the start point of the earliest interval and ends
with the end point of the latest interval.
- Use date axis
- If activated the
x-axis is labeled with the corresponding dates. If deactivated the
x-axis is labeled with the corresponding number of milliseconds since
January 1, 1970, 00:00:00 GMT taken from dates.
- Use row color attribute
- If turned on the color
for the intervals is based on the color attribute of the row. Otherwise
the default color is used.

- Label for X axis
- If activated the X-axis will be named accordingly
- Label for Y axis
- If activated the Y-axis will be named accordingly
- Show legend

General Plot Options
- Type of Image
- The type of the created image can either be png or svg. PNGs are mostly smaller, SVGs provide details about plot and the possibility to be changed individually.
- Title of Graph
- The title of the graph shown above the generated image. If the title is not activated, no title will be shown.
- Width of Image (in pixel)
- The width of the generated image, not the plot width.
- Height of Image (in pixel)
- The height of the generated image, not the plot height.
- Background Color
- The color of the background of the image. Hence this color is used for the area behind and around the plot as well as behind potential axis and legends.
- Plot Background Color
- The color of the background of the plot. Hence this color is used for the empty space in a plot.
- Plot Background Alpha
- The transparency of the plot background can be modified using an additional alpha value. An alpha value of 1 does not change the background transparency. Decreasing the alpha value will increase the plot background transparency.
- Scale Font Size
- Factor changes the font sizes within the JFreeChart view. A value greater the 1 increases all view fonts, a value between 0 and 1 decrease them.
