I've ordered these in importance to me. Thanks for anything you're able to do. Really love these products, they allow me to use Power BI for some charts that would otherwise need to stay in Excel.
I'm using negative values for 1 series because I need the primary axis to be flipped (zero on top). While the secondary axis has zero on bottom. It's for a typical chart in my industry called Depth vs Cost by Day. Depth is increasing as it descends, while cost is increasing as it goes up. Would be great to be able to just invert the primary/secondary Y axis as needed rather than change the underlying values.
Would be great to show currency on the axis label when applicable as well as the ability to choose to display the full comma'd number instead of an automatic abbreviated value, or to be able to select the units like out of the box visualizations.
With Facet axis enabled using 3 series in Line mode (1 on primary, 2 on secondary Y Axis), using Primary Y-Axis with negative values and Secondary Y-Axis with positive values, the zero row for the Primary Axis is getting cut in half (at the top of the chart). Need a top margin so the zero value tick doesn't get cut off on the primary axis.
If the legend could be configured per series, that would help when showing legend marker like triangles, circles, etc... That way I could have a black line twice, but could set the legend marker to the same marker as the line marker to set those values apart.
