How to impose that a XY plot is on top ?

[tycho75]

Hi all,

I use a XY graph to plot a bar graph (an histogram). Then, I want to fit this histogram with a Gaussian Peak and superimpose the result of the fit on top of the histogram. When I do this (see the picture below), the Gaussian peak is always hidden behind the histogram (see the second picture). Is there a way to force the histogram in the background and the result of the fit on top of it ?

Thanks for your help !

Hi tycho,

make your fitted plot the first in the array - right now it is the last.

Do you get the idea? The plot order in the array corresponds to the Z order in the graph display…

Hi GerdW,

That's the first thing I tried, actually, but it's a mess with the different styles (lines, colors, etc.) I want to have for the histogram and for the fitted Gaussian...

When I put the fitted Gaussian at the beginning of the array, it takes the style of the histogram which was previously in the table and the histogram takes the style I wanted to have for the Gaussian...

I'll think a little bit more. 

Thanks for your answer !

Hi tycho,

point 1: Z order in the graph is provided by array index of the plot data

point 2: you need to set each plot's properties

There' s no way around it when you want to have a graph display according to your requirements…

Hi Gerd,

Ok.

Is there a way to programmatically set the style for each graph ?

Hi tycho,

yes, there is.

Spoiler

Use property nodes of the graph! There should be an example VI explaining how to use them…

Hi Gerd,

Ok, but when there are several graphs, which one is modified by the property node ? The one on top ?

Cheers

Hi tycho,

there's a property named "active plot".

Guess what it's for… 😄
