DB Chart TOrgSeries difficult to use

[jls]

I try to use TOrgSeries in a data aware chart

I thought that I could use X and Y values, but that doesn't work

It only uses Y values and the Y values must refer to the row number of the parent node (-1,0,1,2,1......) and not a database value.

This make it difficult to write a SQL (but not impossible) that gives the correct result set.

My suggestion is to use X and Y values as as Parent,Child fields.


I also have some more suggestions
1) add a collaps/expand buttons on the nodes
2)be able to configure the nodes with values from the dataset (color,shape....)

Hi Jørgen,

My suggestion is to use X and Y values as as Parent,Child fields.

Could you please describe in more detail how would you expect this to work exactly?

Thanks in advance.

some thing like this
Name Id Parent

TopNode 12 null
ChildNode 14 12
ChildNode2 34 14
ChildNode3 13 34
ChildNode4 123 12
ChildNode5 2 123


It works if you have data like this:
TopNode -1
ChildNode 0
ChildNode2 1
ChildNode3 2
ChildNode4 0
ChildNode5 5
but this is hard to do because the value is the row number

Hi Jørgen,

Thanks for the information. I've added your requests to our wish-list to be considered for inclusion in future releases.

BTW: Current series' Add method returns an integer which is the point (or node in TOrgSeries) index in the series. Which, in the end, it is what you actually use.
