This takes up a ton of space and I don't want to have to go into the trend control properties to set the axes to visible and invisible when I need them. I want to be able to click on the trend line graph thing and the value axis will change to display only the axis for that particular trend. Is there any way to do this in WinCC V7.0? Any help is greatly appreciated, Thanks!

athleticyeti Posts: 4 Rating: (0)	Cool! Those work great! Just to make life interesting the nextproblem is: The event can't be on a button click. The user needs to click on the actual line of the graph and only the value axis for that trend must show. I can't seem to find events that allow this? Any ideas?

Create for the menübar a picture and show it in a picture Windon on your screen set the property "Display" to "NO" in Graphics Designer. set the property "visible" to "true" by theevent "Focus Change" of the Trend Control add at the menübar (-picture) a button for close, set the standard stettings for the trend control andthe property "visible" to "false" of the picture window. So you will see the menübar when you click at the trend control and you can close if you don´t need it. regards cumulus
