TrendDisplay
This widget allows to display, as graphic curves, samples data collected using function block “GFB_SCOPE”, stored inside the structure “GS_SCOPE_PAR”.It’s possible to display as max as 4 curves at the same time.At runtime it’s possibile to change zoom options and to move the active displayed window (PAN). To activate these options it’possible to set properties “rightVisible” and “bottomVisible”, or clicking over the X axis or Y axis.It has the following properties:background: widget background colorborderColor: border colorborderSize: border sizebuttonSize: zoom buttons size, pixelsgridBackground: central grid area background colorgridX: horizontal space between vertical axis, inside the central grid area. The value is relative to the “curve 1” limits minx and maxx. Example: with minx = 0, maxx = 100 and gridX = 10, the grid area will be divided in 10 equal spaces, drawing 9 vertical lines.gridY: vertical space between vertical axis, inside the central grid area. The value is relative to the “curve 1” limits miny and maxy. Example: with miny = 0, maxy = 100 and gridY = 10, the grid area will be divided in 10 equal spaces, drawing 9 horizontal lines.gridColor: central grid axis colorleftSize: Y axis zoom area size (on the left)leftVisible: Y axis zoom area visible setrightSize: cursors data area size (on the right)rightVisible: cursors data area visible setysize: Y axis values display area sizebottomVisible: X axis zoom area visible setc1_color: cursor 1 colorc2_color: cursor 2 colorcursorGraphColor: default is GRAPH_COLORSGRAPH_COLORS: cursors’ colors are the same of the selected curvePERSONAL_COLORS: cursors’ colors are the user’s colors (c1_color and c2_color)trendSelected: GRAPH1-2-3-4 is the selected trend for left and bottom values changing.
- antiAlias: allows to “round” the graphical “pixel” artefacts (steps) by applying an antialiasing method. For further information about antialiasing, please see chapter “Configuration parameters – Graphics options – Fixed text antialiasing method”.
