One of the most common requests for steem.supply has been a chart for the historical SBD to STEEM conversion (by "historical" I mean a reasonable amount of time, like 7 days). So, after digging up a few API providers, brushing up on my Google chart skills, adding a few functions to the steem.supply codebase and drinking a delicious cocoa and cinnamon concoction I made myself (the secret being adding a dash of cocoa milk, if you really want to know), here we are, with a new feature.

The chart is displaying the last 7 days ratios for SBD and STEEM, or how much STEEM could you get for 1 SBD. The days are calculated in UTC, starting at 0:00. Hovering over points will display the exact price and date. If you want to highlight a specific series, just click on the line in the legend.

There are 3 series: average, open and close.

• average - the average price for that day
• open - the price at the beginning of that day
• close - the price at the end of that day

As you will see, some very interesting trends and correlations can be made with only these 3 numbers.

For instance, today we opened high:

but we're going to close lower:

As always, looking forward to your feedback, criticism and suggestions.
