Bar Chart problem

Hi, I’m trying to show some columns in a bar chart, I have two columns in a dataset

SELECT sum("total1")as "total1",sum("total2")as "total2" FROM informe

This data is showing ok in a pie chart if I set extract order to by row, but using a bar chart is only showing one column.

If I select three columns is only showing the last two columns, if I select four columns, shows the last three.

In a bar chart, the first column of your dataset will be the labels for your bars.
