Flow rate colors need binning about gcodeviewer HOT 3 OPEN

This is a useful tool to me as well, and I agree with you that the color range is not useful.

I would say a continuous black-blue-green-yellow-orange-red-purple gradient (i.e. similar to a weather radar display) is a better idea, with black remaining the lowest-valued color.

Is this ever going to get fixed? come on guys.

This is really annoying. In fact, the "Extrude speeds in mm³/sec"-info is nearly unusably in my opinion.

I was looking for a quick&dirty way to fix it to be able to get mm³/sec for a specific gcode i'm working on. It is far from perfect, but with a few simple steps, you can use it for yourself:

1. Click the green "Clone or Download"-button and "Download ZIP" to get your copy of the files.
2. Extract to any folder you like.
3. Put a textfile in it, call it "start.cmd", and save the following command line:
   start chrome %~dp0index.html --allow-file-access-from-files --user-data-dir=%~dp0Chrome-TEMP\
4. Open \js\renderer.js and insert this line after line 286:
   speedIndex = Math.round((renderOptions["colorLineLen"]-1)* ((extrusionSpeeds[speedIndex]-Math.min.apply(null, extrusionSpeeds))/(Math.max.apply(null, extrusionSpeeds)-Math.min.apply(null, extrusionSpeeds))));
5. Open \js\ui.js and go to line 101. Insert a new line
   var extrusionSpeeds = GCODE.gCodeReader.getModelInfo().extrusionSpeeds;
6. Go to line 115. Replace
   if(speedIndex > colorLen -1){speedIndex = speedIndex % (colorLen-1);}
   by
   speedIndex = Math.round((renderOptions["colorLineLen"]-1)* ((extrusionSpeeds[speedIndex]-Math.min.apply(null, extrusionSpeeds))/(Math.max.apply(null, extrusionSpeeds)-Math.min.apply(null, extrusionSpeeds))));
7. Save everything and open start.cmd. It will launch a new chrome instance that has access to the javascript sources by the --allow-file-access-from-files flag. Now it will look like this:

I know it's not perfect but usable.
If anyone has the time to improve the math, please do it. You can't say you didn't know how to start ;-)

Currently it takes the values of all layers into account, this is why you do not see all 8 available colors in every layer. To fix this, one needs to replace extrusionSpeeds[speedIndex] by extrusionSpeedsByLayer[z][speedIndex], I think...

PS: For convenience, the whole thing is attached as gCodeViewer-master.zip. Download, extract, "start.cmd", enjoy.
