multiple values in stacked waveform chart...how to?

[MSD100]

I am using a single waveform chart which is staked showing 3 Y-axis value on single X-axis platform.....more clearly I have bundled 3 values and connected to single waveform chart......Now, I want to add one more variable to each staked Y-axis....such that my each staked Y-axis have two variable....so that 6 y-axis variable in 3 staked plot(2 in each) having single platform of x-axis in single waveform chart.......

how to do that?

Instead of using single values, just use two-element arrays. That will be 3 two-element arrays.

You need to be more specific in your request. Do you mean if you have 6 parameters, e.g.

1. Pressure - 2 parameters

2. Amps - 2 parameters

3. temp - 2 parameters

You want to display all 6 parameters in in 3 different charts?

Joseph...yes If I have 6 parameteres as mentioned by you and I want to use single waveform chart which is having single x-axis(time) platform....3 y-axis are staked in single waveform chart...

You will need to do the following:

1. Create a stack chart of 6 elements

2. Create a piece of code that will execute at the beginning of your program.

    a. Create a property node to fetch each plot, Actplot->plot (you will need to index each plot)

    b. Create a property node to for the plot->yscaleidx

    c. Set the parameter to the appropriate idx (see attachment), e.g.

     param plot

        1 -> 1

        2 -> 1

        3 -> 3

        4 -> 3

        5 -> 5

        6 -> 5

3. Make sure the parameters are plotting appropriate.

4. Increase the plot height to cover the empty plot (manual operation)

Joseph,

 Can you post the vi,,,I am not able to do that...

I have added image of chart below...which shows 3 staked y-axis...I want to add one more variable in each y-axis..

So let say Y1=25,Y2=35 and Y3=55...I want to add one variable in each y-axis (amplitude,amplitude2 and amplitude3)..

There are 2 vis that do this. Attach is my chart.
