rotate x axis text in d3

January 30, 2023 by Tarik

If you set a transform of rotate(180), it rotates the element relative to the origin, not relative to the text anchor. So, if your text elements also have an x and y attribute set to position them, it’s quite likely that you’ve rotated the text off-screen. For example, if you tried, <text x=”200″ y=”100″ transform=”rotate(180)”>Hello!</text> … Read more

Let me give an example: HTTP. HTTP is a text protocol, even though when it sends a jpeg image, it just sends the raw bytes, not … Read more

How to change the entire theme’s text color in Flutter?

December 22, 2022 by Tarik

I think TextTheme.apply is what you want. bodyColor will be applied to headline, title, subhead, button, body1, and body2. displayColor will be applied to display1 through display4, and caption. If you specify both bodyColor and displayColor and use the same color value, that will effectively change text colors on all text styles. Example: final newTextTheme … Read more

Git has a word diff, and defining all characters as words effectively gives you a character diff. However, newline changes are ignored.
