X Y graph using intense colors

[acacio]

Hello to all,

I have a personal project that is already working fine, I use some inclinometer and laser for measurement. All measurements are displayed at X Y graph.

I would like to represent the signal that a accelerometer is generating on X Y graph being displayed with intense color like the picture attached

The X values is given by a quadrature encoder that display the distance at X, the Y represent the signal from a accelerometer.

I have Sound and Vibration Toolkit installed in case it can help to give a easier solution

Thank you so much

So what is your problem? With an xy graph you can set the color, weight and style of each trace independently.

Hello Mike
What I am trying to do is: for exame, the maximum amplitude of my accelerometer is +- 2 volts.
I would like to have the line or background changing color whenever my signal goes to the maximum or minimum value
For exame, zero volts means color blue, two volts means red color . Like on the photo attached I have posted before
Thank you for you attention

What part of the attached photo are you talking about?

In the chart/graph in the lower part, I see a red line and a blue line.  They don't appear to change colors.

In the top part, I see a couple of pictures that look a lot like a 2-D intensity graph.  How that is supposed to relate to a singular value changing in time like the charts below, I have no idea and you'll have to tell us.

Hello
I am talking about the upper part of the image, not the graph with red and blue
What I am trying to do is get a way to make the color of the line that represent the Y value of the X Y graph change color when the value of the Y changes
For example: when the value of the Y is 0 volt its color is blue, when the voltage got to the maximum value, in this case 2 volts, would change the line color to red
Summarizing, blue Y line would be zero volt, 2 volts would represent red line.
That image I have attached is part of a software that measure the deviation of the rail head dimension using intense color . But in my case I want to measure the signal of the accelerometer displayed its voltage represented by color on X Y graph
Best regards

Hi acacio,

these graphs look like intensity charts/graphs!

Using intensity graphs it's easy to have "colorful" data representations. You need to supply some own program logic to mimic the behaviour of an XY graph…

I agree with you, but I am new o Labview and I dont have that ability to handle it very good
Can you help me or teach me how to do that
Is there a way to control the Y axis of charge usingvfor example a encoder instead time or frequency???
I dont know how to do and I would like to learn
Best regards

Sorry, I have typed wrongly.
I want on Intense chart or graph contril de X value with a encoder
It means the X axis will changr as long as the rnoder is incrising distance
The Y axis will receive values from an accelerometer
Best regards

Hi acacio,

an intensity graph displays a 2D array of values. It's up to you to fill this array with "good" data…

You can use your X and Y values to index elements in the array and set a value in the array!

Ok
I am trying, but I know just very little about use those arrays
Could you help me with kind of VI
I really would appreciated that
X and Y graphs are very easy to handle, i just some build array and index bundle and I control each axel
But with intense chart or graph I am not even close to do that
Thank you
