Hi Marko,Prior to Origin 6.0, the Fill Area plot was created by setting the plot type to High-Low-Close and then selecting the Fill Area check box. In Origin 6.0, it is no longer created this way.
It is now its own plot type. However, you will notice that when you create a fill area plot by selecting Plot:Fill Area that there remains a left over from the past. The Plot Type in Plot Details still lists High-Low-Close.
Our development is aware that this problem and others (as you mention) were unfortunately introduced as a result of the change and that these issues need to be addressed.
For now, the way to get around the problem with the one fill area plot per graph is to create two graphs and then merge them, superimposing the two layers. You can then set the linking and hide the axes for one of the layers.
Yes, unfortunately, you also now cannot independently modify the line style because Plot Details only shows you one of the plotted datasets. I suggest setting the line color to white and leaving the fill color at light gray. The advantage here is that because the line color increments, the first will be white and the second will be light gray which will match the fill color.
