The choice of continuous (and all solid) lines is actually poor design.
Poor graph design = Poor readibility.
First of all, I assume he was aiming for a step line graph (example 3) which would be a huge improve over this.
If the raw data could be shared, I'd make a more readable graph.
It sounds like you may have benefit of using an adaptive moving average type if you're going to be automating your trades. This way, your bot will take into account how volatile a time the price movement is moving within, if that makes sense. It'll keep your bot from taking action on outliers and erratic trading noise, which Bitcoin is very prone to.
I don't know if this is helpful at all, but it appears to be building an adaptive moving average for a coder's use. Here's another explanation of AMA's calculation.
Out of curiosity, what are the two glaring weaknesses you mentioned? I can see how at least one of them would be insignificant crossovers - meaning crossovers that occur when the market is largely sideways and features a very small price range (meaning you'll most definitely lose money to commission fees). With the frequency that these occur, you may find that those fees will eat your bot's entire funding.
I think the percent stacked splinearea chart uses a bad example. In the thumbnail it shows months, which is fine because it is a sort of continuous variable. However, on the actual page it shows discrete values such as "pomade" and "eyeshadows" so it does not make sense to have a spline interpolation between the values.
Yep, there actually is a button in the top right corner that allows you to switch between the two currently available views:
1) all 50+ chart types one by one;
2) 8 groups by purpose, including:
Thanks for the comment! Actually, there are many circular gauges out there, and a lot of our customers make use of them in really diverse ways. The first version of Chartopedia is designed to provide basic knowledge and main principles on how chart types are different from one another. We said Chartopedia would keep on being improved, and this will also result in making the illustrations better.
