Visualizing correlations (Diagram)

The "Chart" widget displays the value of parameters as a diagram over time.

You can select a type of visualization for each parameter.

Use of variables of "String" and "Bool" type

To show more non-numeric information in the Tooltips, select string or bool-type variables. In this way, you can also visualize text for each data point, e.g. a batch number or the customer of a batch.

Procedure

To define widget-specific display options, follow these steps:

1. Create a new widget or edit the existing one.
2. In step 2, select a parameter which is visualized in the widget.
3. Click and open the "Visualization" area.
   
4. For variables, you specify how many decimal places are displayed.
5. Select the color for the display of the parameter.

6. Select the type of the visualization.
   

   • Line chart (Line)
   • Spline curve
   • Area chart (Area)
   • Bar chart (Bar)
     The columns of several parameters are displayed stacked.
   • Scatter chart (Scatter)

7. Activate further options:
   

   • Select whether the value is to be visible.
   • With the bar chart, you can select whether the value is to be displayed stacked.

8. In step 3 "Details", you define the display of the y axes.
   For KPI instances, select the calculation period.
   
   A y-axis is created for every unit that is assigned to a parameter. A maximum of 5 y axes can be defined per widget.
   Each parameter is automatically assigned to a y axis. However, you can also manually assign the parameters to a different y axis.
   You can define a low and high limit for each y axis. This means that you can only display a section between specific values in the widget.
   Alternatively, you can enable "Scale by values". When the display is zoomed, the Y-axis adapts to display the range of values present.
