Poor colour choices with multiple traces

[jsmcortina]

Hi,
I've got MLV 4.2.06 with 4 graphs and 6 traces per graph. I'm not sure where the colour choices come from, but they are working out really badly.

Graph 1: white, red, green, yellow, white again, red again.
Graph 2: green, yellow, white, red, green again, yellow again
Graph 3: magenta, yellow, green, red, cyan, dark cyan
Graph 4: white, magenta, dark green, green, dark red, red

Why so many similar colours? Why not repeat the same colour list for each graph and use contrasting colours?
e.g. white, red, blue, green, cyan, magenta ?

The default colors are set in the MegaLogViewer.properties files.

They currently repeat the same colors 4 times:

Code: Select all

# You can set to any of the colors defined above
graphForeColor0=white
graphForeColor1=red
graphForeColor2=green
graphForeColor3=yellow
graphForeColor4=white
graphForeColor5=red
graphForeColor6=green
graphForeColor7=yellow
graphForeColor8=white
graphForeColor9=red
graphForeColor10=green
graphForeColor11=yellow
graphForeColor12=white
graphForeColor13=red
graphForeColor14=green
graphForeColor15=yellow

In history, years back they did just rotate through like 16 different colors. Is this a long running install? Then the colors could have been changed for those graphs at some point in the past or it may be holding remnants from the past?

if you delete mlvUser.poperties (and mlvUser.properties.bak) from the dir:
~/.efiAnalytics

The colors (and everything else) will go to the default. Otherwise you can set the colors from the menu:
Options --> Graph Trace Colors --> Graph Color n


The key problem you are seeing is the way the colors are selected. The are pulled from a stack of colors over all based on the number of total traces, not from a list per graph. So by changing to 6 traces per graph, it gets messed up.
With the way MLV let's change the number of traces and number of graphs these days, it should pull the colors per graph.
I'm sure if I change that though, it will mess up someone else's color pattern
None the less it should be.

If I change it, anyone want to start a poll on how long before it gets reported as a bug?

I’ve fighting a bit with the coloring too at first.
My workaround was to limit each graph to 3 traces and usually only keep 2 or maybe 3 traces active.
But I still have it easy because I’m using timing only on my setup.

How does the competition do this? (If there is competition being considered ofcourse )

You can just change them and then save down a copy of the changes by exporting the properties to a named properties file. Should you wish to have different screen setups, then simply (re)import the properties file of your choice.

kind regards
