programatically change the color of the horizontal line in scatter plot with ironpython script

[Nivedan Nasina]

Please helpwith ironpython script:

I would like to 1) programatically change the color and line thickness of the horizontal line i added to my scatter plot vai the following script:

or

2) copy the color from another scatter plot horizontal line to a new scatter plot visualization that i have already created.

or

3) change the default color(from black) and line thickness of 2 - so that it sets to the proper color for new horizontal line adds

#Clear all custom lines so the button can be clicked multiple times without piling things on top of each other

fm1.Clear()

horizontalLine1 = sp1.FittingModels.AddHorizontalLine('45')

Thanks a lot for your help.

Try something like this:

 

from System.Drawing import *

horizontalLine1=sp1.FittingModels.AddHorizontalLine('45')

myline=horizontalLine1.Line

myline.LineStyle=LineStyle.Dot

myline.Width=2

myline.Color=Color.Black.#see System.Drawing namespace

myline.IsBackground=False. #set to Foreground in this case

myline.CustomDisplayName='my line name'

 

so horizontalLine1 is one ofReferenceLineFittingModels

myline=vcline.Line is aReferenceCurve, which has the properties being set here

Look at LineStyle Enumeration for different options of style.

Ms Paolini,Thanks a lot for your help. I am trying to find this System.Drawing namespace in the documentation. Are there any easy ways to search or any pointers to find it would be of great help.I got it to work and below code should work for anyone who will look at this later on.there are a couple of "periods" which need to be removed(must have been a test for me ;)) ###############################################from Spotfire.Dxp.Application.Visuals import *from Spotfire.Dxp.Application.Visuals.FittingModels import *from Spotfire.Dxp.Application.Extension import *

TIBCO namespaces start with Spotfire.Dxp. System.Drawing is a Microsoft namespace, see here:

 

https://docs.microsoft.com/en-us/dotnet/api/system.drawingview=dotnet-plat-ext-5.0

 

For TIBCO API and IronPython, there are many pointers starting from here:

Notes:

when i used the spotfire documentation for ironpython functions/api etc for version 7.6 there was no search feature available....

https://docs.tibco.com/pub/doc_remote/spotfire/7.6.0/doc/api/topic=html...

but then i randomly stumbled upon the documentation for spotfire rev 11 and saw that there was search feature:

https://docs.tibco.com/pub/doc_remote/sfire-analyst/11.0.0/doc/api/TIB_s...

I strongly recommend everyone to switch over to the latest documentation to avail the use of the search feature --- incase u didnt know.....

Getting Error name LineStyle Not defined

[Gaia Paolini]

It works for my tests, The complete script, including the imports, is below. Note that LineStyle is part of the .NET API.

from System.Drawing import *from Spotfire.Dxp.Application.Visuals import *from Spotfire.Dxp.Application.Visuals.FittingModels import *from Spotfire.Dxp.Application.Extension import *#Get a reference to the current visualizationsp1 = Viz.As[scatterPlot]() horizontalLine1=sp1.FittingModels.AddHorizontalLine('45')myline=horizontalLine1.Linemyline.LineStyle=LineStyle.Dotmyline.Width=2myline.Color=Color.Black #see System.Drawing namespacemyline.IsBackground=False #set to Foreground in this casemyline.CustomDisplayName='my line name'

Thanks much Gaia. It worked after adding missing imports.
