Hi all i would like to know what settings should i do to my waveform graph so i can display hourly electricity usage for a day. I only want 24 markers on the x axis and for this graph to only update once every hour and reset after 24 hours. The picture bellow is something like what i would like to achieve.
Solved! Go to Solution.

No setting
use XY graph... and put time stamp in the X and Kw/h in Y.
The formatting will be done automatically. You can set custom details in the parameter of the XY graph.

Hi,
you can directly edit the waveform graph by going to its properties and setting the X-axis to 24. Under the scales section of Graph properties make sure you remove Autoscale, set min value to 0 and max to 24. please see below
Resetting the graph can be done via setting the property node (value) to 0. make sure you initialize a counter for each hour ticks which will reset the value for this Property node to 0.

Use a Waveform Chart. Set the Update Mode to be "Scope". That will cause the display to clear once it reaches the end of the display. To make it even better, have a good look at my nugget here: Sporadic Waveform Chart
