Associated with: Trends and X-Y-Z Plots
The Bad Data state is indicated by a purple marker (by default) on a Trend or X-Y-Z Plot’s trace.
The color indicates that the quality of the value may be bad (the value is unreliable and may be inaccurate).
For data sources that exist in the Geo SCADA Expert database, Geo SCADA Expert obtains the marker color from the data source's Color Palette. The exception to this is if Geo SCADA Expert is unable to obtain the marker color from the server (for example, if communications with the server is interrupted when a Trend is redrawn). In such a situation, Geo SCADA Expert uses the marker color that is specified in the Options window. Geo SCADA Expert also uses the marker color from the Options window for data sources that are from a non-Geo SCADA Expert database (for example, another OPC database).
