Bricks/boxes instead of lines

[jjalonso]

Hello guys

Great project. This is not an issue is a question. I'm interested to use renko charts. Renko is a simple chart where if value increased on a specific amounts for example +20 it will create a upper box/brick and if after it it reduce to -20 the current value then it will show the brick/box down.

I wanted to know if there is a workaround to do it using this lib or if it could be easy to modify and some suggestions for me to do it. On other canvas based chart projects it can be done using range bars. Thanks.

Check the screenshot. And ignore the bars ar the bottom edge also ignore the lines/wicks coming out the bricks.

@jjalonso hey) The idea to support candlestick charts and renko charts is great. If you can draw a sample of a black&white Renko chart below using the box-drawing characters and GitHub markdown – we can try to add the support for it. Colorizing the chart is not an issue, however, drawing a readable renko chart with bodies and tails can be tricky. I suggest that you post a sample (draw it by hand) below:

```

your chart drawn with box-characters here

```

great, gonna try. Is not possible to use directly the blocks elements characters for the renko? there is boxes directly as one char.

there is few geometrical chars too, but not sure if it can be used.

@jjalonso it could also look like this:

█   █
 █ █ █             ╷    
  █   █    ╷       │ 
       █   █       █
        █ █ █     █ █
         █   █   █│
              █ █ 
               █

We will try to find combinations of symbols to draw it, and will add it, hopefully, soon. If you find a better-looking set of characters for Renko charts, let me know.

My suggestion (using ▁▂▃▄▅▆▇█ chars)

[jjalonso]

Sorry for the late reply (years) but Im not working with the lib anymore. Sorry about that.

unfortunately not seen any project plotting streaming data nicely like asciicharts. candlesticks and indicator plots were required.
