Timeline bar with same colour for same activity

[atpwtacha]

I have some data I want to present as a horisontal stacked bar

9	0.033333	Ready
9.033333	0.033333	Talking
9.066667	0.016667	Not Ready
9.083333	0.05	Talking
9.133333	0.016667	Work
9.15	0.033333	Talking

Its a time serie. Hours in decimal as first column, time elapsed in second and activity in third. I want to present it as a horisontal stacked bar chart where each group of activity has its own colour (so the two talking categories has the same ecolour) and the lenght is based on its time elapsed. Is there a workaround that would allow me to do so?
