Easy Chart Builder - percentage bars?

[ferpont]

Hi there, I am new to this forum so I say hello to everybody!
I am actually trying to make this sweet plugin do the following: I want three chores to be displayed in just ONE groupname showing their progress in time as percentages. What I really want to show is the progress of different chores in the construction of a house, like "ceiling" "floors" "walls", but still to no avail... If I write percentages in the groupvalue (I use just one group) the chart is only extending up to the higher value, but not showing the 100%... I am racking my brains, but no cigar.

This is the shortcode on my wordpress page:
[easychart type="horizbar" height="50" title="Obra Montañeses: Progreso de Obra" groupnames="Progreso Obra Montañeses" groupcolors="005599" valuenames="Losas,Muros,Terminaciones," group1values="50%,30%,10%"]

Any input?
Yhank you in advance!

Yeah, it scales the values to fill the plot area and this causes problems with folks plotting percentages.  If its acceptable to you you can cheat a bit by creating a sole white 100-value bar and shove your values in group2values:

[easychart type="horizbar" height="50" title="Obra Montañeses: Progreso de Obra" groupnames="Progreso Obra Montañeses," groupcolors="00000000,005599" valuenames="Losas,Muros,Terminaciones" group1values="100" group2values="50,30,10" ]

Worked!!! 
I don't know why, but I had tried a very similar method with no success, maybe because the sole was set as three bars on the groupvalue1 and the whole chart as a horizontal bar stack. All resolved now wit your code, which I shall take as a reference for future charts
Thanks for the help!
