I'm doing a Line Chart using the HighCharts component in OS 10, and I need to add dataLabels to a specific dataPoint.
To do it, I'm iterating over a list and calling the DataPoint_Init to get the data point record. Then I'm doing some validations and according with that I'll show a dataLabel with a specific style. To do it, I'm creating an AdvancedDataPointFormat record, setting the AdvancedDataPointFormat.DataPoint and then the AdvancedDataPointFormat.DataPointJSON with the following value:
After this, I'm adding it to the AdvanceFormat.DataPointFormats structure and this structure is being passed in the chart block.
This is a mobile application, and for that reason, this logic is being called after fetch the data in the aggregate. The line chart is generated and I can see it, but for some reason the dataLabels don't show up. What am I missing?
Thank you all in advance,
Instead of doing the configuration on the DataPointJSON, try setting the parameter AdvancedFormat on the line chart block with the following value:
Does that work?
This will give you the same label for all points. From what I understand you need different labels for different points, so you'll need a formatter. If you can explain the rules for the different labels, I can try to give you an example.
