how can i get the default colormap to be JET in matlab 2014b?

old colormap JET was better. how do I get it back?

Answer 1

There are two different things getting confused here.

There's the Colormap. The default for that changed from jet to parula. As Steven said, you can easily change the default for that using the instructions he pointed to. The Colormap is used by objects which are converting numeric data into colors. Examples include scatter, surface, and indexed images.

Then there's the ColorOrder. The ColorOrder is used by commands which just want to create a bunch of different colored objects. Examples include plot and errorbar. The default ColorOrder also changed in R2014b, but neither the old nor the new ones have names. The old one looked a bit like jet, but it actually wasn't quite. To get the old ColorOrder back, you would need to do this:

set(groot,'DefaultAxesColorOrder',[0 0 1; 0 .5 0; 1 0 0; 0 .75 .75; ...
                                   .75 0 .75; .75 .75 0; .25 .25 .25])

It will probably still look a little different because of the antialiasing. That softens the colors a bit so they don't pop quite as much as they did in old versions. You could turn off GraphicsSmoothing if you really wanted them to look just like the old days.

set(groot,'DefaultFigureColormap',jet)

I tried this but the plots don't have jet colors. how do I get the jet colors as default in the plots?

[Steven Lord]

We haven't removed JET from the product, we simply change the default. You can add a command to your startup.m file to change the default colormap following the instructions in the documentation. The property whose default value you want to set is the Figure object's Colormap property.

hi

the plot colors don't change. how do I get the plot function to use jet colors?

[Sean de Wolski]

Change the 'DefaultFigureColorOrder'

[Leo Diaz]

colormap does not change the plot colors, just the surf and pcolor ones. new plot colors are hard to see. the old ones JET were much much better. can I have them back?

Sean said:

Change the 'DefaultFigureColorOrder'

That should be 'DefaultAxesColorOrder'. The Colormap is on the figure, but the ColorOrder is on the axes.
