200 mBTC Bounty - Support Stacked Bar Charts

[lucasgray]

Hey Tim, thanks for the charting library! Looks great.

It would be excellent to support Stacked Bar charts, like these

https://developers.google.com/chart/interactive/docs/gallery/barchart#stacked-bar-charts

Both as 100% stacked, and the absolute stacked.

What do you think?

Thanks for the compliment. I'll put it on my todo list. Adding that feature should be quite easy. Right now, I have no time, but hopefully in a month or two...

[lucasgray]

Cool. Drop a note when you start. We may have a need before that and may give it a whirl ourselves. Also eyeing that pie chart request.

Hi there. I started looking at this one. How does this bounty thing work?
Best regards,
George

@ge0rg0 Just create a Pull request with the new feature. I can review it, give feedback, you'll probably have to tweak a few things. When finally accepted, give me your BTC address, and I'll pay you.

I have found an tricky solution to this.....
So, i want to show you a demo of this ....just a simple not heavily codes.
should i email you or creat pull request?

[joshafest]

I have created pull request.....of this....have a look over xchart-demo...../bar/BarChatStack.java
I know it is not the absolute stack but work similar to that .......well the implement of new thing can make xchart a heavy weight which should not be ok......so , I used overlapping trick,
Any way , I deserve atleast 2/3 of the bounty.....

Hi,

I commited a more generic solution, which I started working on some time ago. I created a demo file based on the example done by @joshafest

[joshafest]

he need new functionality not an...just examples using old one.....well ....i am just near to complete the functionality....lol...

[ge0rg0]

It is new functionality, just the demo data is the same. I can create new demo data.

[joshafest]

i mean to say .. ...he did not need overlaping ....if your do not have that than ok....let him reply...

[joshafest]

I am working on it....but some trouble with zero transform and yTransform.
Moreover if we replace (zeroOffset) with (zeroOffset - yOffset) the bar should became a horizontal line but it is not happening.

[joshafest]

I am very near to crack this issue.

Done. try with latest snapshot jar. BarChart03 demos it.
