options in MCGraphIRF

[indrani_5]

I realised that MCGraph does not have a stylenum option. Is there any other way to incorporate changes in patterns of graphs under this command? I want to distinguish the color and pattern of confidence bands from the responses in MCGraphIRF.

The responses use style 1, which is solid black whether in color or B&W, and the error bands use style 2, which is solid blue in color and a on-off dash pattern in B&W. You can redefine either or both of those styles. If you're looking for something much more complicated than that, you would need to use @MCPROCESSIRF to process the information and construct the graphs with the desired options.

Just following the instructions on the referred page. I dont know if this works with montevar command. Is this the right way to do it?

Will it apply? Yes. To the B&W representation. It redefines line styles 1 and 2 for black and white. (It also defines 3 and 4, which aren't used). Whether is does what you want is questionable. That defines style 2 as a light gray line (.9 is the level of "grayness" where 0 is black and 1 is white) which will barely show up in a 6 x 6 table of graphs. What are you trying to do different from the standard?

[indrani_5]

I want to replace the solid blue lines of the confidence bands with dashed blue or red lines. How do I achieve this? And can we have more examples on how to customise these things. Its not at all clear from the refferred page.

[TomDoan]

This will keep the solid black for style 1, while thickening it a bit and use a dotted red line for style 2.

line_color_1=0,000000,3 ;* Solid black thick
line_color_2=1,FF0000,3 ;* Dotted red thick

If you want blue, the second argument would be 0000FF (100% blue) rather than FF0000 (100% red). If you want dashes (equal length on and off but with longer lines and gaps), you would change the first argument to a 2. That probably won't work as well as the dots when you do a 6 x 6 matrix---you lose the detail when the segments are too long relative to the size of the graph.

It's not a heavily-used feature, so we don't have a lot of examples.
