Variable Comparison
Require: IP-Symcon >= 6.0
This module was sponsored by IB-Jaetzel.
The module creates a graph of point clouds based on one or more pairs of variables and a line through the point cloud using simple linear regression. The diagram can be output as SVG or PNG.
feature
- Create a diagram with one or more pairs of values
- Output of the diagram as SVG or PNG
- Output of slope, y-axis intercept, function and coefficient of determination of the graph
software installation
- Via the Module Store install the 'VariableComparison' module.
Set up instances in IP-Symcon
- Under 'Add Instance' the 'VariableComparison' module can be found using the quick filter.
- More information about adding instances in the Instances documentation

status variables
The status variables/categories are created automatically. Deleting individual ones can lead to malfunctions.
Status variables
| Name | Type | Description |
|---|---|---|
| Function | string | Specifies the mathematical function of the graph |
| b | Float | Describes the y-axis intercept of the graph |
| m | Float | Describes the slope of the graph |
| Coefficient of determination | Float | Describes how exactly the graph fits the point cloud |
| Start Date | Integer | Date from which the point cloud should start |
| End Date | Integer | Date to which the point cloud goes |
| Chart | String / Media | Returns the chart as PNG or SVG depending on the setting |
