Doubt about matrix or array

[altenbach]

The english language has enough idiosyncracies to fill books. It is not better, and probably worse than most other languages. We are just used to it. 😄

I'm drawing the lines in white color. But can I change the color of just one line, like red one, and the others continuing at the white color?

Because when I try to change the color, it changes the color of all lines.

Are you referring to any particular post? What are "the lines"?

Attach a VI to illustrate what you are trying to do.

If you run my .vi, it will generate random lines at the graph. 

That lines are data that I'm receiving, and I'm drawing them (I'm simulating a track that my car is doing). If I want to change the

color of a specific data, how can I do that? 

I used the property node-> plot -> plot color. But it changes the color of teh all plot.

A plot can only have a single color. To display multiple colors, you need to graph to multiple plots.

Please do not post VIs which run forever!  Replace your false constant wired to the loop termination terminal with a front panel boolean control, such as a Stop button.

It is still not clear exactly what you want. With regard to the image below are you trying to change the color of the segment from X=5 to X=6 with a different color?

One way to do that is to have separate plots for each color. Initialize all the arrays with NaN (Not a Number). NaN values do not plot. Then as you read the data use Replace Array Subset to put the new data into the plot which has the color you want for that segment. You may need to put segment endpoints into both plots.

Thanks Lynn. it is exacly that what I want.

I will try what you said.

I would strongly recommend to use a 2D picture for this.

try this rough draft ...

uowwww... that code will help me a lot

Thanks!!!!
