DFVisualizationSettings component#
Hint
This component is automatically adding to the canvas all the input parameters for the component.
Inputs:
|
Which values to display. |
|
Select a color palette to map the values to |
|
Thresholds the values with a maximum value |
|
Thresholds the values with a minimum value |
|
Set the total height of the legend |
|
Set the total width of the legend |
|
A construction plane for the legend |
|
Scales the height of the histogram with a factor |
Outputs:
o_viz_settings |
Settings to be passed to the Visualization component |
