As to the acceleration curve chart, if it is an unreasonable amount of work to truncate the graphs so that they do not always end in 0km/h and 0kN, then it is better to have them like this than not.

As I explained a few months ago, this has a complex problem.

In the real world, the theoretical value is drawn from the calculation formula. But in the patch the numbers use in-game calculations.

In this example, the maximum speed is 8km / h and the chart is drawn up to 8km / h.

The problem is the value of max speed, but when ask the function for the acceleration force at max speed, 0 is returned. Because otherwise convoy will accelerate above the top speed.

The same is true for resistance. If the acceleration force is 0, the resistance force is not 0 or the balance cannot be achieved.

We have to change it so that you can get the theoretical value for the chart. But the code was written by Bernd Gabriel and is definitely a black box for me.

The second problem is the drawing of graphs. All the charts that exist in simutrans today have a fixed number of x-axis in advance. In this case it is 24. Draw a graph using up to 24 arrays. Making this a flexible x-axis number instead of a fixed number is a new system that I can't do with my skills. The maximum speed can change each time player change the configuration of the convoy in the depot, and it has to change the number of arrays and redraw each time.

And as explained before, if the maximum velocity is a prime number, the x-axis will not be all integers except the both ends.

Therefore, the x-axis is drawn by the integer span, but since the number of arrays is fixed, there are cases where it does not fit neatly like this.

The top speed is 56km / h, but the existing x-axis is 54 and 57.

The only way to draw this correctly is to flexibly extend the array as explained or create a system that draws a line in the middle of the axis.

Thus I think it would be difficult to achieve it.

You can easily check the maximum value by turning the graph on and off.

Can I ask whether this is ready for a final review? If so, I should be grateful if you could list all the translation texts for this branch.

It's ready to be reviewed.
