Datapoints
The user can add multiple data points to the Bar Chart, each as a separate series of values.
Formatting
Different colors and descriptions can be set for each individual data point series and will be shown in the legend. The value format and the unit are set manually, inherited from WinCC OA, or deactivated. The unit can be manually chosen from an overview of SI units. The separate series can be grouped together. Multiple groups can be placed beside each other in the graph.
The groups can be presented stacked and equiped with a tool tip to show the data point address. A value range can be set automatically or chosen manually. The gap between the different series can be set manually, with a set default of 0.8. Grids can be set to appear along the x or y axes with the respective check boxes. A legend for the data point series can be placed in a variable position on any side of the graph. The data zoom settings determine along which axis a zoom happens. Zooming can happen along either the x or y axis, along both axes or be deactivated entirely.
