LabVIEW graph Update mode

[piZviZ]

I am able to update LabVIEW graph from left to right or right to left , but is there any way that my graph can be updated from center(middle of graph)?

Hi piZviZ,

is there any way that my graph can be updated from center(middle of graph)?

How should that look like?

Anyway: with a graph you can control the x axis (using property nodes) very nicely. You can also determine which and where to add points/samples in the plot(s). This should work with a waveform graph. In case of problems you can also use the XY graph with even more control of the the points in your plot(s).

Graphs don't "update", they just display whatever data comes in on the wire. Are you talking about charts instead (they have several update modes!).

Please explain what you mean by "middle"? For a chart, you can definitely set the x-scale in a way that there is space on the other side of valid points, i.e. the update occurs in the middle. A waste of pixels, but maybe that's what you want. 😉

Please attach an image to explain what you have in mind.

Yes, I want same thing which you told about chart update. Can you post a simple example.

It is not clear what you are replying to and I told many things. Sorry, I was wrong, you cannot set the axis outside the history length, but you could use use a black decoration. Still seems quite silly. What's the purpose of all this?
