Height of bars in days with more than 50 contributions is always 153 about github-profile-3d-contrib

I tried the following formula.

(log10(x*12/5+1)*72 + min(x,50)*3) / 2 + 3

It is uncomfortable to have a small number of contributes.

I thought of using the following formula.

log10(x/20+1)*144+3

It is a little smaller, but I think it is acceptable.

Hi formidablae. Thank you for your proposal.
I think the idea of using logarithms is good.

The formula for finding the height is as follows.

• Previous height: h1(x) = min(50, x)*3 + 3
• New height: h2(x) = log(x*N+1)*K + 3

To determine N and K, I set some constraints.

First, if there are fewer contributions, I want to make the difference smaller than before.

• h2(0) = h1(0) = 3 and h2(1) = h1(1) = 6
• h2(1) - h2(0) = 3
• log(N+1)*K - log(1)*K = 3
• K = 3 / log(N+1)
• h2(x) = log(x*N+1) / log(N+1) * 3 + 3

Next, I want to display the number of possible contributions at about the previous maximum size.
I think it's about 1200 contributions a day.

• h2(1200) = h1(50) = 153
• log(1200*N+1) / log(N+1) = 50
• N = 0.1008515...

Rounding off the fine numbers, we get the following.

• h2(x) = log(x/10+1)*72 + 3

However, 1200 contributions per day may be too much.

You are welcome @yoshi389111 :)
Your adjusted solution is better. I didn't know about the max 1200 contributions per day.
Nicely done that reverse parameter calculation!

However, 1200 contributions per day may be too much.

Yeah, you are right. But, since the heights of all days will be recalculated, there shouldn't be unusual differences between them (even with way less contributions than 1200).

Did you do produce any 3d svg with the new formula? Are the heights too low or too high when compared to the heights obtained with the old formula?

[yoshi389111]

I didn't know about the max 1200 contributions per day.

I may have misled you.

1200 is not the maximum number of contributions per day on github.
It is the maximum number of contributions that can be displayed in this tool without overlapping or overflowing.

Are the heights too low or too high when compared to the heights obtained with the old formula?

With this formula, the display seems to be too small.

I would like to adjust the formula so that it can be displayed a little larger.

1200 ... is the maximum number of contributions that can be displayed in this tool without overlapping or overflowing.

Oh ok, now I get it.

With this formula, the display seems to be too small.
I would like to adjust the formula so that it can be displayed a little larger.

Did you try doing an average of the old linear formula and the new logarithmic one?

Wow, the second one looks wonderful! Even though the absolute height of 51 contributions/day would now be lower than before, the differences between the heights of different days would still be very distinguishable, colors help too - so that last formula works perfect (for me at least :) ).
