    I'm creating a TKChartOhlcSeries using an array of TKChartFinancialDataPoint. The data is graphed but the data for each data is a simple vertical line...without any open/close ticks. Is there a some palette or style that needs to be set?

    Hello, Jeffrey,

    Thank you for contacting us.

    To calculate the correct width of every OHLC bar we need to know what is the maximum amount of bars which will fit on the plot area. To calculate this amount TKChart uses the minorTickIntervalUnit property of TKChartDateTimeAxis, which should be set to a unit corresponding to your data points interval. Consider the code snippet below:
    TKChartDateTimeAxis *xAxis = (TKChartDateTimeAxis *)chart.xAxis;
    xAxis.minorTickIntervalUnit = TKChartDateTimeAxisIntervalUnitHours;

    I hope this helps, if you have further questions do not hesitate to contact us.
