How to contribute to this project?

[abhi1992]

hey,
I would love to contribute to this project. It is something I love like kotlin + graphs. It's absolutely useless to build my own chart library as you have made tremendous progress here.
So, I want to help in contributing to this project, I am a software developer for 7+ years and I am comfortable in any new languages as long as it's not purely functional ( I hate them. ).

If you could suggest me some bugs that I can start off on I can take off from there and see where I can land.

Thanks in advance,
Abhishek Banerjee

Hi Abhishek!

How about this feature request: #596 ?

For reference see also the lets-plot Kotlin variant of ggsave() which already supports PNG and JPEG export.

For the work you will need to clone this repository and setup a local dev environment. Don't be shy to ask any questions.

Another candidate to take a look at is this future request: #76 which has been pushed down the road for quite a long time.

Also, we very much appreciate any sort of interesting content which is created with lets-plot and published.

In lets-plot-kotlin some of the API still has insufficient documentation or no documentation.

---

As you can see you can help in various ways )

Hey, thanks a lot for the reply. And I am really honoured to be a part of this. I was looking around the code base for both the features. And could make some progress and understand a bit. I maybe wrong with my interpretation though since all I did was chase the rabbit hole and dumping conclusions. But here's what I found for issue #76 :

interface PointShape {
val code: Int

fun size(dataPoint: DataPointAesthetics): Double

fun strokeWidth(dataPoint: DataPointAesthetics): Double

// fun create(location: DoubleVector, dataPoint: DataPointAesthetics): SvgSlimObject
}

We have set PointShape.code as integer. Is it the cause we are unable to see the strings?
Also, is there a standard email or help channel I can use rather than a public github disussion for this?
Thanks in Advance!

This issue is a bit tricky. You have to look at the ShapeOptionConverter.
Out of ggplot2 specs for the shape aesthetic we only support

• An integer in [0,25]

• A . to draw the smallest rectangle that is visible, usualy 1 pixel.

The idea in #76 is to add support for few mnemonics, like "+" for shape 3.
Note, that such mnemonics are not in ggplot2 specs, but they can be found in Matplotlib (see link in the issue).
