I am using ComposedChart from Recharts. How can make the values on XAxis start from zero point?

So I made a point system for a game on the TI-82. The points are stored as the variable P. I first tried using the Disp command to display the variable and text at the right place, but that didn't work with mixed text and variables. So instead I switched to using the output command, but that always puts the variable and text at a fixed position, which means that as the variable gets more digits, the space between the variable and text shrinks. I tried using the log of the variable for the position, but that didn't work because most of the time it returned decimals. Here is my current code for displaying the points:
Output(2,1,P
Output(2,3,"POINTS
Does anyone know how to increase the spacing between the variable and the text depending on how many digits the variable has?
Log works if you round it down and add 1.
int(log(P)) + 1
will give you the number of digits. Why not just round up instead? Because log(10) = 1 but 10 is 2 digits.
This is pretty simple, just put the variable after the points, so instead of doing:
Output(2,1,P
Output(2,3,"POINTS
Do instead:
Output(2,1,"POINTS
Output(2,8,P
I just wanted to know, how do I pass multiple clips to animation-mixer?
The extension GitHub mentions that the clip parameter accepts clips(s). I have tried to add multiple clip names separated by comma and in array, but nothing works. How does it work?
model.setAttribute('animation-mixer', {
clip: '["Idle", "Laugh"]',
loop: 'once',
crossFadeDuration: 0.4,
timeScale: 1,
})
The animation-mixer component does not support multiple animation names. However, if you use the asterisk(*) at the end of the word. Then, it will generate a Regexp that will match every clip that starts with the word before the * and everything after it.
E.g.
Idle* will be converted into ^Idle.*$ Regexp, therefore, any clip that starts with word "Idle" will be matched.
I was trying to wrap the labels of x-axis on next line as the labels length is quite long. So is there any way to achieve it. I tried using calculate and labelExpr by breaking the label string and then concatenating them using '\n' but that doesn't seem to work.
Is there any other config which will help me achieve this use case or any workaround ?
You can refer the config here - vega-lite.
Newline characters in strings cannot be used to display line breaks. You can generate a line break in most Vega-Lite strings by instead passing a list of strings.
For your chart, you can generate line breaks using the split() operation in a calculate transform:
"transform": [{"calculate": "split(datum.address, ' ')", "as": "address"}],
The result looks like this (view in editor):
I'm trying to figure out how the PuTTY terminal numbers its rows and columns.
Does it start from 0,0 or 1,1?
I'm using VT100 to set the cursor and it's important to send the right count.
I want to force the cursor location like this: ESC[1,0f and I expect it to set the cursor on the second row (starting from zero) and the first column.
The separator is semicolon (;), not comma (,).
VT100 escape sequences number starting at 1;1 and generally will interpret a zero as a missing parameter, which makes that 1 as well.
Some terminal emulators may do unexpected things with an explicit zero, most handle missing parameters, e.g., \033[1f means the same as \033[1;f

This is part of a pipe-separated file (I know....) that I'm trying to load into MySQL.
I'm trying to use regex to fill empty field values with \N so that MySQL will insert null. However this is a problem when there are multiple fields that are null values.
My current regex is /\|\|/ which matches one instance of double pipe. This regex will match once at index (0,1).
Is it possible for regex to match ||| twice? Once at index (0,1) and once at index (1,2)?
If no, I'll just write a proper looping function.
I'd suggest using look-arounds:
(?<=^|\||\n)(?=\||$|\n)
It finds the zero-width space between to vertical bars, or between a vertical bar and start/end of the line/text (=empty field).
The first part, the positive look-behind (?<= checks that the position we are interested in is preceded by start of text ^, a vertical bar | or a new line \n.
The second part, the positive look-ahead (?=, ensures it's followed by vertical bar, new line or end of text $.
See it here at regex101.
Edit
As per comment, added support for empty field at start of line. (Had to check, but from what I can see ruby supports look-behinds. Original if someone needs it in JS: \|(?=\||$|\n))
