How to display the linear equation of a graph?

[RUBEN MJ]

Hey all,

Do you'll know how I can display the equation of a linear graph, ie. y=mx+c

I have already plotted the graph and I wish to display the equation of the graph.

In MS Excel you could display the equation and I am trying to do something like that in LabVIEW.

Is it possible?

Thanks for the help

Regards,

Ruben

Hi,

I think the best way is to programatically change the caption of the graph.
1) calculate the coeffs (m and c) of your linear plot
2) build a string such as "my equation is y = m%s + %s"
3) Change the caption of the graph (property node) with this string

You can place the caption where you want on the graph.

Best regards,

I want to linear equation graph of y = 2x + 4 in microsoft excel. How do I
do this? On my TI-83 Plus I could easily do this. I also know I could create
a data table and use the table of values to chart the line in excel. But I
want just enter the equation in excel and have excel graph it. Thanks.

This is a LabVIEW forum. If you need help with excel, I am sure there is a better place to ask.
