}Reason: These lines of code - revisit when removing need for double data
if (signMax <= 0) {
from = min;
to = 0.0; // was 0, caused issues in Interval typed as double.
} else {
from = 0.0;// was 0, caused issues in Interval typed as double.
to = max;
}Fixed README.md error - images failing to show (mzimmerm#8)
Implemented change in mzimmerm#5 - allows to set paint on line chart hotspot circles
Added the following new line chart options in charts/line/options.dart
ui.Paint hotspotInnerPaint = new ui.Paint()
..color = material.Colors.yellow;
ui.Paint hotspotOuterPaint = new ui.Paint()
..color = material.Colors.black;
double lineStrokeWidth = 3.0;Implemented change in mzimmerm#6 - line chart allows to reverse order of data series (dataRows) to make the significant series line to be on top
Added the following new chart options in charts/options.dart
bool firstDataRowPaintedFirst = true;Moved the following to options in charts/options.dart (from being hardcoded)
painting.TextStyle labelTextStyle = new painting.TextStyle(
color: material.Colors.grey[600],
fontSize: 14.0,);
ui.TextDirection labelTextDirection = ui.TextDirection.ltr;
ui.TextAlign labelTextAlign = ui.TextAlign.center;
double labelTextScaleFactor = 1.0;New name reflects the usage better.
This version finally fixed issue mzimmerm#2 - flutter charts not actually working as a library package (reason: incorrectly specified dependencies).
- Only changes in documentation. Also publishing using
flutter packages pub publishinstead of previously incorrectpub publishwhich resulted in a package that reports error on clients' getting the package usingflutter pub get. Hopefully this change will fix the issue. Below is the full error this new version is trying to fix:
The following log is from a test app in https://github.com/mzimmerm/flutter_charts_sample_app. It is mostly relevant as a documentation of the issue, client apps can ignore this.

pub get failed (1)
- Only changes in README, to figure out how to include images (turns out all links must be external)
- Initial push. Line chart and (vertical) bar chart support. Various options supported.
This package follows Semantic Version 2.0.0. http://semver.org/
Example: 1.2.3 means MAJOR.MINOR.PATCH
Development: Major version zero (0.y.z) is for initial development. Anything may change at any time. The public API should not be considered stable.
API Stable versions: All versions with the same MAJOR, where MAJOR>0 must have the same API.
