Shinobi Controls - use the hoop data point

Question

I've got a test Shinobi Control chart working but wnat to put a hoop, "O", at each data point. How do you do this?

Answer 1

You need to set the point color on the series style object appropriately. The series which have the ability to show point (SChartScatterSeries, SChartLineSeries, SChartBandSeries) all have a pointStyle property within their style object, which is an instance of SChartPointStyle. This has the following relevant properties:

• innerColor
• color
• innerRadius
• outerRadius
• showPoints

Depending on the effect you want (and the series type you are using) you need to set these appropriately. For example, to show 'hoops' on an SChartScatterSeries, you could use the following for the data source method:

- (SChartSeries *)sChart:(ShinobiChart *)chart seriesAtIndex:(int)index
{
    _series = [SChartColumnSeries new];
    SChartScatterSeries *series = [SChartScatterSeries new];
    series.style.pointStyle.innerColor = [UIColor whiteColor];
    return series;
}

Note, if you're using SChartBandSeries or SChartLineSeries, these have showPoints set to NO by default, so you would need to set this to YES yourself.
