Most JavaScript chart apps have no builtin support for Japanese price change charts, but they can be emulated with other chart types. Here we generate one builtin Renko chart with the Microsoft ASP.NET Chart control and one emulated Renko chart with amCharts:

Price Change Charts

Our price change charts are in fact regular line charts using the same data passed to the Japanese price-based charts. They make it easy to detect all price values and their variation. Here is such a simple chart, with data labels on:

Specific Renko Charts

Most our demo Renko charts – as the ones above – use by default a box size of 10%. The following two emulated amCharts Renko charts have a box size of 5% and 20%:

Beyond Candlesticks Examples

In 1994, in his Beyond Candlesticks reference book, Steve Nison described in detail line Renko charts, with two great examples. Here are two of our emulated charts – with FusionCharts – using his data from the Tutorial and Practice samples:

Microsoft ASP.NET Chart Examples

The Microsoft ASP.NET Chart control comes with some great online samples. One of those examples uses specific data, and you may set the box size parameter to different values, to generate specific Renko charts. We used same data here below, and here are our emulated Renko charts for FusionCharts, with 0.5/1/1.5/2 box sizes:
