How to make the strip chart scrolling

[HaoLe]

Hello all,

I am a novice in LabVIEW. I have to read in a voltage signal and display it in real time similar to what the Real-Time Chart.vi in the examples ship with LabVIEW does. However, I could not manage to make the chart scrolling like the axample vi. Instead when the chart gets to the left border, it stays there and the new values keep piling up that makes the chart shrinks smaller and smaller.

Do you have any idea how I would do to get the chart scrolling along? I would appriciate very much.

Hao Le,

Check the value of the "Chart History Length" and also choose a proper 'Update Mode' for the chart. This option is under the "Advanced" property. Otherwise, attach a VI that only depicts the problem.

Hope this information is helpful.

Hello;

You can take a look at some properties of your chart, such as "update mode" and "history lenght", however, you can always open the Labview example, select the chart, and copy and paste it on your other VI. You can even use Ctr+C and Ctr+v as a regular windows object.

Hope this helps.
