Hi,

I’m building a heatmap with UniformHeatmapRenderableSeries I would like to know if it is possible to get some text inside each block.
I would like to display the block size when I zoom in like this https://www.scichart.com/example/android-heatmap-chart-with-text-example/.
Do you have any suggestions?

Best Regards,
Gabriel

Hi Gabriel,

The WPF (Windows), iOS & Android versions of SciChart support text in heat map cells natively, which is shown when zoomed in, but hidden when the text is too small to view.

At the moment, SciChart.js Javascript chart doesn’t support text in heat map cells, but I have logged this as a feature request here:

In the meantime you can use our TextAnnotation feature to place labels on charts which zoom and pan with the chart, however you will need to show/hide these on zoom by listening to axis.visibleRangeChanged callback.

Best regards,
Andrew
