View Full Version : sencha chart scatter series - use dots as markers

Hi -

I'm writing an healthcare app that's heavy on charting - lots of datapoints to be displayed on a chart, multiple charts visible at a time. All series are scatter series.

I am looking for ways to make the charting faster - now, on browser resize, or initial data load, it takes some 4-5 seconds for all the data to draw.

One of the ways I'm looking to speed up the charting is trying to use dots - simple pixels, one pixel would be awesome - instead of the circle markers used by default for scatter series. I'm thinking it physically takes less to just drop a dot instead of drawing a circle for all datapoints in the charts. Any way to achieve this?
