## Defining separate Z marker values for separate rows of a 2D array plotted on a single intensity graph

let's say I have a 2D array containing three rows and five columns. First row has elements 1,2,3,4,5,

second row has elements 6,7,8,9,10 and third has 11,12,13,14,15. I want to define Z marker values separately for each row but all within the same single intensity graph plot. How do I do that? Altenbach your input would be greatly appreciated too 🙂

## Re: Defining separate Z marker values for separate rows of a 2D array plotted on a single intensity graph

Hi blessedk,

so you want a color ramp with entries for each integer between 1 and 15 (including)?

Just create such a color ramp: There's a property node of the Z axis to define an array of (value, color)-clusters!

## Re: Defining separate Z marker values for separate rows of a 2D array plotted on a single intensity graph

Hi Gerd,

i actually want to create separate "Z marker values property for each row. Since each row has a unique range of values, one single " z marker values" would not work for all rows. So for row 1 which ranges from 1 to 5 I would like to have a z marker value property just for that row and for row 2 with values from say 2 to 6, I want to have another z marker property to handle that specific row.

## Re: Defining separate Z marker values for separate rows of a 2D array plotted on a single intensity graph

Hi blessedk,

one intensity graph with one z axis with one colorramp. That's all to say…

You need to combine your z marker values into one color ramp. And you can have upto 254 values in the color ramp (plus underrange and overrange)…

OK. I thought so too. So it is right to say that the multiple "z marker values" approach won't fly. Thanks.

## Re: Defining separate Z marker values for separate rows of a 2D array plotted on a single intensity graph

Hi blessedk,

you can create your own "z marker selection" for each row on the FP. But in the BD you need to combine those "selections" into one color ramp for the intensity graph…
