<div class="markdown_content"><p>Trend auto axis do not work as intended when using exception values (Not a number, infinity...)<br/> Tested with Codesys 3.5.16.3 and previous with CODESYS Control for Raspberry Pi SL</p> <p>Expected behaviour using minus infinity :<br/> -a point out of the Y axis range is added<br/> -the point is lower than the Y axis range<br/> -the point is not used to calculate the Y axis range<br/> Current behavior : (see green curve of attached project)<br/> -a point is added at the top of the Y axis range<br/> -the Y axis seems to range from minus infinity to plus infinity<br/> -other values seems to be displayed as zeros (probably a scale problem)</p> <p>Expected behaviour using Not a Number value :<br/> -no point is added<br/> -a break appear in the curve<br/> -the Not a Number value is not used to calculate the Y axis range<br/> Current behavior : (see blue curve of attached project)<br/> -a point is added at the top of the Y axis range<br/> -the Y axis disappear<br/> -the Y axis reappear and the Y axis range is calculated only with the values following the Not a Number value</p></div>
