Hello Everyone,
Im new to the developers community. Im an experienced PowerBI user, but I faced a new challenge I would like to solve, maybe with the development of a custom visual.
Let me describe the scenario.
Im connecting to a SSAS, Multidimensional. So I cannot Use DAX, or create further metrics than the ones that are provided by the cube Im using.
There is a metric, wich is a percentage of variation. There is a Category Dimension. There are four categories. The data in the table would look like this:
Category Dim | Var %
| Category1 | | 5.2% |
| Category2 | | 3.2% |
| Category3 | | 5.1% |
| Category4 | | 4.2% |
The Column Chart They use today (created with excel chart, over a table) has the following information:
- X-Axes: the 4 categories and 1 more column named 'Total'
- Y-Axes: the % value.
In PowerBI I use the column chart. I add the Dimension as the Axes, The metric as the Value.
This chart shows me 4 columns, but I'm unable to add the Totals Column.
I tried to use a Waterfall Chart, but the proble, is that the waterfall chart "adds" de percentages, instead of using the disagregated of the dimension.
Why? , because the total % I want, is not the sum of the percentages of the dimension, but the metric calculated withour the drill down.
I tried different ways to do this in PowerBI without much success. Im thinking that the best way to do this is to implement a custom visual. I think I could be able to modify the column chart, but I need some guidance.
What I want to add: I want to add 1 more column, with a value that is taken from a Metric, without drilling down by any context.
For people that has developed visuals before, what is the best way to approach this ?
I would appreciate any help over this.
Thanks a lot,
Alejandro.
