Requests: Line Graph Baseline & Pie Chart Hole about peity HOT 10 CLOSED

It would also be nice that the baseline could be set to an arbitrary angle for burndown charts and other similar needs where we want to check if the line follows and ideal or expected trend.

Adding a baseline to the line graph: You're not the first to ask for this sort of thing and I've been giving it some thought. I'd like to tackle it by exposing the information that the chart has about how the input numbers map to output x and y positions which would allow you to query this data and further decorate the chart.

Donut chart: This would be a different type of chart.

Although they're named differently, the functionality is identical. The only difference being the donut may sustain more data, however in this case they would be too small to do so. Adding an optional hole would be an aesthetics gain.

Though a minor detail, it may produce a big difference.

I've put together a JSFiddle of the piechart with a donut hole. I've also managed to integrate it

Would be fantastic if you could add this as an option into peity.

Those donuts look great :D

I want to add donuts but I'd like to do it by drawing each sector of the ring instead of using a mask as it will enable some further features.

I've done a little work on exposing the data to allow extending a chart with arbitrary baselines and the like. Here's an example of adding a line:

Have a play and see what you think. As you can see it's a manual process so unlikely to be used (!) but it's actually made the internal code cleaner and easier to fathom.

I have a branch with donuts on, it's built on the changes that allowed baselines and the like:

Here's an example:

Donut charts are now included in version 3 of Peity which also exposes the mapping functions between values and x/y coordinates on the <svg> allowing you to further decorate the charts.

Brilliant stuff. Perhaps make note about the baseline on the homepage, so others can see it's do able.

Thanks, will do. I've opened a work-in-progress pull-request that builds on this work: #45
