Hi everybody,
If I use a 'trend' object in a graph and when I close and open again the graph, the 'trend' object is empty and the traces restart from the beginning.

Is-it possible to keep the graph in memory (when close it) and retrieve the 'trend' state like before close the graph?

For example in Visual Basic it has a 'hide' method permitting to keep a windows in memory.

Thanks a lot for your help.

Hi Ben,

No, I'm afraid it's not possible. The Ge Component Trend does't have any mermory. To store a trend you have to use the DsTrend or DsTrendCurve objects, and there is no component in Ge to display them in a graph. It is though possible to combine trends and Ge graphs in a multiview window.

Hi Claes,
Thanks a lot for your comment.
Have you plant to add this feature in a future Proview release?
I think this may be very interesting to have a 'trend' object (with continious traces) directly in the 'process' graph for example to follow a specific variable with a short time line (without need DsTrend function).

Hi Claes,
Maybe to solve this problem, it is possible to iconify a graph (not close it) by specific command.
I can see in documentation that 'open graph' command has few options like =/iconify, but 'close graph' command hasn't options (?)

For the moment for close my graph I use a button with "close graph" command attribute but maybe it is possible to use a command just to iconify it ?
If it is possible it is the solution because the graph don't appear but it's always in memory.

Thanks for your advices.

Hi Ben,

Adding a /iconify option to the 'close graph' is a good idea. It will be implemented in the next release.

Hi Claes,
In Proview 5.5, is it possible to use some trick to iconify a graph window?
Maybe we can use a 'iconify graph' script called by a 'script' command (button).
Unfortunately I do not know enough about the linux environment and the script language to write this type of sript.
If you or somebody has an idea I will be very interested
