Is it possible to add the trend line for lineChart about swiftuicharts

[willdale]

Would using a MultiLineChart do the trick?

There are different ways of calculating a trend line depending on what you're doing.

How would you like to be able to use it? ie from the perspective of initialization.

I'm make an EV management software, so I'd like to demonstrate a line chart to show the relationship between battery decay and odometer.
In this given situation I think a trend line will be very useful to indicate the slope.

I'm not sure what you mean by "trend line" that can't be achieved using a multi-line chart.

Can you clarify please?

Linear trend line added in v2.2.0

The View Modifier probably needs to placed quite near chart.

.linearTrendLine(chartData: CTLineBarChartDataProtocol,
                 firstValue: Double,
                 lastValue: Double)

Thanks
