Plotting a graph with array values

[Nghtcrwlr]

I have a 2D array. The first colum is the X axis values and the other 4 colums each Y axis .

How can i plot such a graph?   A graph with 1 X axis and 4 Y axis sca

Hi Nghtcrwlr,

use DeleteFromArray to get the first column and the remaining ones. Then use an autoindexing FOR loop (on the Y data) to build an array of plot for a XY graph from each Y column and the X column:

Thanks GerdW . I am planning to have 4 diferrent Y axis Scales. I duplicated the Y scale 4 times. I found out the max n min in each column to set the Y scale range according to it. But it seems one can only scale the Y axis in general using PropertyNode.

Is there any way to scale each one using property?

Hi Nightcrawler,

did you notice the property "Active Y Scale"? Did you read it's help entry?

I am having a graph with 3 Y-axis scales. Temp, Current & Gear Efficiency. I want to set each axis a specified range ( min & max)
I tried using the property for graph "Plot.YScaleindex" for each scale and then setting min max. But somehow it is not wroking properly. Does anyone have any idea? Is it not possible to scale all 3 scales at a time?

Hi NightCrawler,

do you actually read the answers you get on your questions?

If yes: why don't you follow them?

(There's a reason why I moved your message into this older thread of yours!)

Hi GerdW

Sorry for the misunderstanding. Soemthing else was in my mind. The actual problem was: the Y scale of my second plot ( gear efficiency) always changes to another scale ( to temperature) . It only happens to Gear efficiency. All other scales remains same as saved.

Are they set to Autoscale?

[Nghtcrwlr]

No . they are not set to autoscale. It happens only when i press Autoscale button. So i guess it has something to do with property node

Hi Nightcrawler,

AGAIN: Please read the answers you get - and read them carefully!

I recommended to use the property "Active Y Scale", but you used "Plot.Y Scale Index".
