Graphics Support Help
The Graph Window is a configurable window for viewing statistics as linear graphs or bars graphs. You may add several graphs to the Graph Window. Adding new graphs may be done via checking the appropriate check-boxes in the parent dialog window. The graph parameters configuration is provided via five buttons placed in the bottom part of the Graph Window:
Stop Button ("Red Hand" image)
Click the Stop Button in order to stop drawing new statistics points in the Graph Window. In order to resume click the Stop Button again.
Grid Button
Click the Grid Button in order to get the coordinates grid. In order to take it out click the Grid Button again.
Legend Button
Click the Legend Button in order to open the Legend Window. You may watch the current statistics values there. In order to close the window press the Legend Button again or close the window via its system menu.
Help Button
Click the Help Button in order to get this help topic.
Options Button
Click the Options Button in order to open the Options Dialog. Using the dialog you may configure Graph parameters.
Polling Interval
Changing the value will affect the Graph Window and the parent dialog as well. The change will affect only polling for this specific dialog. If you want to change Polling Interval for the whole device please use Describe Window.
Min Y, Max Y, Min t, Max t
You may change the scaling ranges for Y-axis and X(t)-axis via these parameters.
Automatic change of ranges (Y and X(t))
If the appropriate check-box is checked the system may change Min Y, Max Y, Min t and Max t automatically. Note, if the X-axis presents time the X-check-box must be always checked. For Y: sometimes it is better to turn off the Y-check-box, especially when graphs have peaks.
Show in the graph.
You may select one of the three options:
a) Show Actual Value (e.g. number of packets)
b) Show Relative Value (e.g. packets/sec);
c) Show Value in percents. This is the same as a) but data are ranged from 0 to 100%.
