Setting a color/size/etc within the legend, but not setting the defined value for a color/size/etc will not display with the analysis is launched from the Web Player.

For example, adding multiple marker layers in a map chart.  Each layer you set to a different fixed color, without actually setting a value for the color. 


When you publish this same analysis to the Web Player that legend is missing.

This is as designed.  The web player will show as much of the actual visualizations in the analysis file as it can. You will need to set a value for the “Color By”, then this will cause the Color to show in the legend.
