So I have a legend at the center bottom of my chart. Is there any way to make it multi-lined when it has these properties?

pContent->GetLegend()->SetVerticalAlignment(xtpChartLegendFarOutside);

pContent->GetLegend()->SetHorizontalAlignment(xtpChartLegendCenter);

You can try ChartLegend.ColumnCount

I tried setting that ColumnCount with no luck. It seems to be ignored in my instance. When I did a call to GetColumnCount() it was returning a zero, even though my displayed legend had what I thought was 9 columns all one one row.

Yes, default 0. Appears a bug, however it will not effect performance. 0 and 1 both mean 1 column, 2 = 2 columns, etc.

I just tried ChartControl.Content.Legend.ColumnCount = 2 and it displayed 2 columns (only 4 items total).

This returned 2:

Debug.Print "column: " & ChartControl.Content.Legend.ColumnCount

In my testing with this, I used SetColumnCount(2), and getting the following results:

TopToBottom: LeftToRight:

1st 3rd 2nd 1st

2nd 4th 4th 3rd

5th 5th

I would think that if it worked correctly, I should really be seeing the following orders:

TopToBottom: LeftToRight:

1st 4th 1st 2nd

2nd 5th 3rd 4th

3rd 5th

I took look and not sure what problem is. I test both and get your expected results. Please post entire chart you use so I can reproduce.

Also ColumnCount can be 0, only in case xtpChartLegendLeftToRight. If xtpChartLegendTopToBottom then it will use 1 when ColumnCount is 0. So default is 0 in all cases, just know it see 0 and test for direction, if xtpChartLegendTopToBottom it use value of 1.

In the picture used xtpChartLegendLeftToRight and 2 columns. Added data in this order: NY, CA, FL, TX, OH
