To be honest I do not have anything concrete, but I do have some code that I used during dev testing for this.
It is a PHP file that generates SQL insert statements for the BTC_DOGE market. It generates 10 weeks of mock transactions that you can pipe into MySQL. I am attaching the code in case you find it useful. Do not use it before reading what it does. It will delete your database data and replace it with random data.
Once a market has enough data, you will be able to see the candlesticks on the chart.
