PixelPerfect pie chart bug on percentage label

Hatus — Fri, 15 Nov 2024 21:01:15 GMT

When a pie chart or a donut chart is natevely created in the PixelPerfect template, there is a bug displaying the last label of the percentage.

In fact if the last percentage and first percentage values are between 1% and 3% than their label get swapped clockwise after the first label. Wrongly displaying the labels.

The Resolve Overlapping Mode property behavior does not move the label to the right side. See attached images.

It happens on all NPrinting versions.

How can this be fixed?

Kind regards

Hi @Hatus

Yes they were swapped but the tracing line is correct so label is attached to correct segment. Yes - it is not above the segment (as I guess you want it, but at the same time it is still correct providing the trace line from green segment to 3% box.)

@Ruggero_Piccoli - can you comment on that? I dont have experience with labels for such small values as I never use them in pie charts due to visualisation practices involving such small values in pie chart

cheers

Hi,

I have to develop an example to reproduce it, before I can suggest to test different option settings. The internal library who manages PixelPerfect reports is the same in all version of Qlik NPrinting so I suppose upgrading will not change the behaviour of cross linking the labels.

You could also test to reduce the size of the inner circle to have more space between it and the border of the chart.

Hi @Ruggero_Piccoli and @Lech_Miszkiewicz

Thank you for the reply.

I tried many properties and it has to do finally with these properties: SweepDirection and Rotation

In order to get the pie chart in the correct direction I used SweepDirection=Clockwise and Rotation=270

It messed up the small values.

However, using SweepDirection=Counterclockwise and Rotation=90 I get the small values display correct BUT I have to reorder the data comming from Qlik table chart in the opposite order. It works like a mirror so to speak. I was expecting it to work 1-1 with the Qlik app.

See attachement.

Hi,

Data comes from Qlik Sense but the native PixelPerfect charts are created by the related library.
