Strip Chart Autoscale

[jschafer10272]

Is there really no easy way to AutoScale my Yaxis in CVI on a stripchart other than the example of keeping a history and rescaling it manually with the history...


thanks,

Unfortunately yes. Autoscaling is only available for the graph, not for the stripchart. So you have to set the min and max value programmatically for the y-axis of a strip chart.

Fortunately, this should not be too difficult to do. Basically I would approach it like this (as long as you want to only have the scale grow, if you want it to shrink back, that takes more logic and requires that you keep track of what is "on chart"):

Define two variables to hold the min and max scale values.

If the current value is more negative than the min, set min to that value, change the scale minimum.

Else, if the current value is more positive than the max, set max to that value, change the scale maximum.

Else do nothing.

Here is an example of how to set this up
