Trend widgets plots on a graph how data collected for several parameters varies over a time series.
Select one or more parameters you want to monitor.
Remember to select at least one parameter. Otherwise, you will not be able to save the widget.
Textual (usually short) description for the plot. It will be visualised in the widget header.
On/Off button which toggles the presence of a legend next to the plotted data (default: OFF).
Sometimes Omnyvore collects a huge amount of data, even for a single thing. Therefore, a very dense plot may incur performance problems as the number of points increases. This option allows you to select the maximum number of points which are plotted on a graph (default: 500). Throughout this page, we will refer to this value as L.
Function which Omnyvore will use to aggregate data points which are close, but only when the aggregation limit is exceeded. The available aggregation functions are:
On/Off button which toggles the aggregation on time intervals (default: OFF).
Trend widgets can display data for more than one parameter. In order to choose how a parameter will be plotted:
Pick a colour for the line of the graph which represents the parameter (default: random colour).
Plot the data points as if they were a step function, i.e., only using vertical and horizontal lines (default: OFF).
Do not show anything but points, i.e., lines will not be present in the graph (default: OFF).
The dimension of the points, in pixels (default: 1).
The shape of the points: square, circle, diamond or cross (default: circle).
