How do I get the chart to start from ZERO?

[marc france]

Hello everyone,

Could anybody tell me if it's possible to use a chart that shows the acquisition since Time Zero ( instead of moving forward ) ?

Thanks a lot,

Marc

You have to set a suitable chart history length ( based on number of Points you want to display on your chart) and selecting the x axis scale 'start' as 0 and 'end' as ( chart history length-1)

Also, disable autoscale X axis in the pop down menu of your Chart

Hi devchander,

Thank you very much for your answer. I was actually wondering if it was possible to have a chart that needn't to have to set it's history length. The last data would be plot at the end of the history ( so that the length of the history changes it self). I am not sure I am very clear... lol

Do u know if this exists...?

Thanks,

Marc

That would be a graph, but you would have to build your own 'history' and feeding each run all the data. With LabVIEW 8 and a x-control it would be possible. but you would fill all the available memory of the PC!
