Unit Trend

The TTrend component is a graphical component designed to show an animated plot of parameter values. As values are added old values scroll off the graph to the left. The trend can be viewed in a number of ways // tsBar - Each value is represented as a rectangle tsLine - A line is drawn connecting each value tsScatter - A small rectangle is drawn at each value ts3D - Each value is represented by a 3D rectangle tsFilled - As tsLine except that the area below the line is filled // A few options can be applied toValues - On tsBar and ts3D text values are added to each column. toTwin - Two values are displayed for each slot // One area where the last option is useful is when monitoring systems with demand and feedback values. Here it is important to know that a given command is tracked accuratley. Differences between command and feedback are especially well highlighted by using ts3D and toTwin // Mark Dodson 3rd July 1997 //
