Improve combined Chart options

In a combined chart, it would be nice to have the following options :

• To choose the characteristics of each line: dashed line, thickness...)

• To have vertical lines: e.g. have a vertical division between past and future (time on the horizontal axis)

• To choose the location of the line abscissa: Currently, a line is a series of points with a horizontal position in the middle of each bar chart. It would be interesting to be able to choose to place it to the left, middle or right of the histogram.

  • For example, if you have a combined chart with time on the horizontal axis, you can have a bar chart with the amount of products sold per year (horizontal axis category = 2019, 2020,...2023) and the line could be the P&L. The P&L is calculated at the end of each year (31 December). It would be more visually pleasing if the points of each P&L were displayed towards the intuitive position of 31 December (between the two years).

• To improve the marking when you click on a line within the visual. Currently, if your labels are only displayed when an item is marked, all labels are activated when you click on a line within a visual. Novice users think it is a bug because this behaviour is not consistent with clicking on an item in the legend.

  • Also, suppose you have 2 identical combined graphics sharing the same tagging and you only display the labels of your tagged items: if you click on the line colour of your first graphic from the legend then: only the labels of that line are displayed on the first graphic (as expected) but ALL the labels are turned on on the second graphic (bug?)
