pichukov / lightchart Goto Github PK

Thanks a lot for this awesome library - it's a joy to use, and one of the few truly light and functional SwiftUI chart libraries out here. 👍

One thing I noticed:

I assume this happens because the line stroke is equally applied to both sides of the line, and then cut off by frame. It would probably make sense to vertically move the chart inwards by half of the stroke width, so that the stroke is no longer cut off.

Thanks again!

The chart does not show anything if all the elements in the array is same

Ex:

LightChartView(data: [10, 10, 10, 10, 10],
                               type: .curved,
                               visualType: .filled(color: chartColor, lineWidth: 5),
                               currentValueLineType: .dash(color: .gray, lineWidth: 1, dash: [5]))

I've even tried adding an offset, but the result is still same

LightChartView(data: [10, 10, 10, 10, 10],
                               type: .curved,
                               visualType: .filled(color: chartColor, lineWidth: 5),
                               offset: 0.2,
                               currentValueLineType: .dash(color: .gray, lineWidth: 1, dash: [5]))

Current behavior

• The chart does not show anything if all the data are same

Expected behavior

• The chart shows a horizontal line if all the data are same

Please fix this.
Thanks so much for this amazing SwiftUI library.

This is not a bug, just a feature suggestion.

LightChart already comes with the currentValueLine, which draws a horizontal line at the last known value and works great.

I would like to suggest adding two more line types:

• a firstValueLine (showing the first value in the data row)
• one or multiple customValueLines (showing a horizontal line at a value to be defined by the user).

Background: I use LightChart for stock charts. It would be nice to draw a line at the first value of the chart (e.g. the opening price in the morning) or another arbitrary value (e.g. 0 or the closing price of the previous day).

Thanks for considering this! It's not urgent, but I think it would make a nice addition.
