We have added a new sample application for InduSoft Web Studio that makes use of the stacked bar graph symbol created as a part of our free symbol library. This sample application offers more information on using this symbol in your SCADA or HMI projects.
To use the symbol, specify the tag name, min and max values of the engineering unit range for the tag, the limit point for the caution value (i.e., when to start drawing the bar graph in yellow), and the limit point for the warning value (i.e., when to start drawing the bar graph in red). If you only want two colors then make the caution and warning limit values the same value. The project includes a screen called “main” that includes the TriColorBarGraph symbol that uses the tag called “Second”. It also includes an exploded, unlinked version of the symbol showing how it works.
