<div class="markdown_content"><p>it seems to have something to do with the use of reference variables. I have the XY chart in a frame, the interface of which looks like this:<br/> VAR_IN_OUT<br/> ChartData: ARRAY<span>[1..1440]</span> OF REAL;<br/> END_VAR</p> <p>Change it to this, and it works:<br/> VAR_INPUT<br/> ChartData: ARRAY<span>[1..1440]</span> OF REAL;<br/> END_VAR</p></div>

<div class="markdown_content"><p>Any ideas why an XY chart would display like the attached screenshot? The curve variable is an ARRAY<span>[1..1440]</span> OF REAL, at the time of the screenshot only a few of the variables had values, between 15.7 and 21.6, and the rest were 0. Autoscale on the y axis is turned on, so I would expect to see the scale between 15.7 and 21.6. Instead i'm getting these massive numbers on the scale.</p></div>
