Waveform chart not showing history in X scrollbar

[Evan117]

Hello,

Looking for help with the VI attached, the waveform chart for pressure is not allowing me to scroll back through

the X-axis chart history. I have tried selecting/unselecting every option I can find but no luck. Would be grateful if

someone wouldn't mind having a look and suggesting a solution, thank you very much.

Regards,

Hi Evan117,

the problem is there are no data in history. Your waveform chart shows 1024 points (0-1023) and chart history length is the same so all data are shown in chart. Right click to waveform chart, select "Chart History Length..." and enter a bigger value than 1024. After that your scroll bar will be working.
