Hello,

I have a doubt with the formatting of labels in a pie chart:

The data for the pie chart has two columns: EventName and Duration where Duration is in seconds.

Is there a way to format the label to display the duration like "hh:mm:ss"?

I tried to write an expression binding for the "labelFormat" property, but without success

Thank you

You have to format it in the binding. For example, if the data is bound to a SQL query you can do something like:That function above exists in MySQL so it might be different depending on your database.

Thank you Travis,

Yes, I thought about that, but the problem is that Duration is precisely the quantity that is being graphed, and I might have troubles if I cast it into a string, isn't it?

No, you just want to alter the first column which is the name of each wedge. Leave the duration column alone. It will be a numeric value.

Mmmh, yes, it can work but I'd loose the Event Name, perhaps I can concatenate the Event Name and the formatted duration.

I think it would be great that the labelFormat property could accept formatting codes, something like:
"{1:d}" or "{1:format('hh:mm:ss')}" or "{1:#,##0}" or something like that.

I see. You would have to concatenate the two values since there is a single display for each wedge.

Thank you very much Travis
