Gauge graph, partial pie and partial donut graphs #121

Open JamesMcIntosh opened 6 years ago

JamesMcIntosh commented 6 years ago

By adding a parameter for arc length to the arc renderer. Using the existing configuration at least three additional graph can be accomplished, see images below.

Example config for Gauge Graph:

new charts.PieChart(seriesList,
    animate: animate,
    defaultRenderer: new charts.ArcRendererConfig(
    arcWidth: 60,
    startAngle: 4 / 5 * pi,
    arcLength: 7 / 5 * pi,
  ),
);

Gauge graph arc-graph-gauge Partial pie arc-graph-partial-pie Partial donut arc-graph-partial-donut

I take that this has not been released yet?

This page details how to create a gauge graph, but the arcLength is not present on current version, 0.4.0

lorrainekan commented 5 years ago

Yes, it has not yet been released.

@VyMajoris You can use git repos as a dependency and specify "dependency_overrides" element in your pubspec to get early access to it.

https://www.dartlang.org/tools/pub/dependencies#git-packages https://www.dartlang.org/tools/pub/dependencies#dependency-overrides

Add something like this to your pubspec.yaml (untested).

dev_dependencies:
  charts_flutter: 0.4.0

dependency_overrides:
  charts_common:
    git:
      url: git@github.com:google/charts.git
      path: charts_common
  charts_flutter:
    git:
      url: git@github.com:google/charts.git
      path: charts_flutter

@JamesMcIntosh

Thanks! I didn't know that.

supermarcos commented 5 years ago

@JamesMcIntosh That didn't work for me... I literally copied and pasted exactly that code under my dev_dependencies section (although I didn't put charts_flutter: 0.4.0 under dev_dependencies: because I already have it under dependencies: (and it makes more sense there).

Any idea what could be happening?

The error I'm getting is 

Could not find a file named "charts_flutter/pubspec.yaml" in https://github.com/google/charts/tree/master/charts_flutter..."
pub get failed (1)
exit code 1

Also, @lorrainekan any idea about when is it going to be released?

Thank you!

JamesMcIntosh commented 5 years ago

@supermarcos the error message is pretty specific, it can't find the yaml file. Did you add both dependencies? Try and turn on verbose logging when running the flutter command.

flutter packages get -v

Look for the pub command and run it manually setting --verbosity=warning to --verbosity=all, i.e.

<PATH_TO_FLUTTER>/flutter/bin/cache/dart-sdk/bin/pub --verbosity=solver --verbose get --no-precompile
supermarcos commented 5 years ago

Hello, @jamesmcintosh Thanks for replying. Yeah, the message seems pretty specific... and confusing. The yaml for the proyect is there and the yaml for each of the libraries are inside the url written so I assume something else may be happening, but the error in that case wouldn't be correct or, at least, is confused. Any other idea? I will try those commands when I have time and let you know. Thank you!

H @JamesMcIntosh I tried the commands you told me and I got this:

Correct me if I'm wrong but that looks like permissions... could that be? How can I clean that cache folder?

@supermarcos You probably don't have SSH access set up for git, use a HTTP format git URL instead.
