Time Axis on Waveform Chart porblem

[plpablo]

Hello all,

I have problem with values on time axis on my Waveform Chart. I would like to start axis form 0s and end automatically at the end of the measurement. 

But I have some strange value you can see on the picture

Hi plpablo,

use a graph to get a good customizable time/x axis…

Charts are limited here!

Graph will be updated in realtime ? 

[GerdW]

Hi pablo,

the graph will be updated when you wire new data to its terminal…

Hi GerdW,

As you suggested I changed chart to Graph. 

Now my 10 s measurement looks like picture in the attachment but it should end in the middle of the graph. How to customize time axis  ?

Auto scale

When I Use auto scale I do not see mesurmet form the beginning. 

I need to see graph from 0s to the end on of the plot.

Hi pablo,

I need to see graph from 0s to the end on of the plot.

Then you need to collect the needed data for the graph, similar to the history of a chart.

Did you examine the example VIs coming with LabVIEW in the example finder? There is an example explaining the differences between charts and graphs and how to use both…

according to information found here :

if I want add dynamic data in the loop I should use chart, but in chart I have problem with time scale. 

so question is chow to work with graph in loop or how to get time axis right in the chart

Hi pablo,

did you look for example VIs in the examle finder?

Anyway, here's an example:

Don't get used to DDT wires and your life will become easier…
