    HI!  I have a chart with two thousand Candlesticks.  The only time the DateTimeCategoricalAxis shows readable values is when I'm zoomed all of the way in.  Is there any way to show a sampling of approximate values values as I zoom out?

    Hello Louis,

    We do not have an adaptive-sampling feature yet. Perhaps you can use the ChartDataSource to turn sampling on. Then in the ZoomChanged event of the chart you can set the SamplingThreshold (in accordance with the zoom level) to some number that will ensure that you have 50 (for example) visible candlesticks. Give it a try and let us know how it goes.
