MrDeathStar Posted July 2, 2015 Posted July 2, 2015 I am plotting a digital output value vs. time with the step (21) plotting method. However, I noticed that the rise is drawn before the run when a new data point arrives. Is there any feature to allow the opposite (i.e. draw horizontally first and then vertically step up/down to the new value)? The horizontal line on the graph would then indicate the digital value over its time period. If this is a 3rd party graph limitation (i.e. like I found that right axis cannot have step), then I will proceed with regular point/line plotting methods and pad my channels to create the step. Thanks.
AzeoTech Posted July 2, 2015 Posted July 2, 2015 Can you post a simple example showing what you are seeing?
MrDeathStar Posted July 3, 2015 Author Posted July 3, 2015 Sure...I provided a quick example. Just curious if this is an option in the current codebase, or if I must simulate it. StepPlottingTest.ctl
AzeoTech Posted July 3, 2015 Posted July 3, 2015 I'm not sure if there is a setting, per se, but there is an easy work around. In the X expression for your trace, instead of Time, put: testStep.Time[1,100000] what that does is use the next data point's time stamp, which does what you want.
MrDeathStar Posted July 3, 2015 Author Posted July 3, 2015 Ok, good idea. I had not thought about that option. However, even though the most recent data point is missed, the starting condition is strange and the work-around fails badly in the PulseB example. For now, I think I will continue with my double channel entries to simulate desired behaviour. Maybe a step drawing order could be considered as a future feature request...(and availability on the right axis too). In any case, thanks for your quick response!
