Origin Ver. and Service Release (Select Help-->About Origin): 2018b
Operating System:10
I have a graph with many dataplots, some as Yerr
I'd like to get the color of the error bars.
With GetFormat, the color returned is -9 with mean "auto", as far as i understand.
How can I get the actual color number ?
Thanks |

Hi,
So far, it seems that we don’t have a general method to get the exact value of “auto”. We could only get the value of the treenode that the “auto” follows instead. Like the color of error bar:

This is exactly what I'm trying to do.
The Yerr dataplot treenode will tell me the wks range of the parent Y, but from there, do I need to loop over all plotted dataset to find that Y ?

Hi,
Yes, I am afraid that there is no other good method so far.

Just ran into a special case:
- plot line+symbol and set another color with toolbar icon shortuct
- change plot to scatter with toolbar icon shortcut
--> There is no more Line information but symbol color is set to auto (i.e -9)
From here, how can I get that auto color ????

What do you plan to make use of it if you can get the color?
The auto rule is quite complicated, and if the plot is for example set to By Points mode, it will be not a single color then.

I'm building a color gradient that goes from dataplot color to another color, if single color. So I must get the dataplot color.
But that's OK if I can't. The function will just do nothing if symbol color is -9 and no parent line.

Then the color is another value ( > 2*256^3) and I know it is a by point color |

Could you tell how I can get the value of the treenode that the "auto" follows ?
Couldn't find anything in GraphLayer treenode
