For one of my Saturday Streams I decided it might be fun to play around with graphs on the RGB LED Matrix.
As I'm sure you have heard me mention a lot, these RGB LED Matrix displays are one of my favorite displays you can use for Arduino. They are relatively cheap and easy to use, you can check out the video I made on it here:
I decided that bar charts would be a good type of chart to start off with as they are relatively simple and should look nice on these displays. This was the result of the stream:
I was really happy with how these came out!
When drawing the chart you specify the area you want it to take up and the chart will automatically adjust its height and width to fit into this area while maintaining the ratio the data being displayed.
I think next steps for this project would be to turn it into a library so it is easier to consume.
If you want to check out the code from the stream you can get it here:
