问题描述

我想将 Capitalomega 与索引 DE 和 k 标签:

I want to put Capitalomega with index DE and k label:

然后我想显示在 y 轴标签上?怎么做?

and then ı want to show on the y axis label? How to do them?

推荐答案

一般情况下，您可以在 Veusz 中使用 tex 符号.因此，您可以为您的请求编写 \Omega_{DE} 和 \Omega_{k} .查看详情此处(第 2.4 节文本).

Generally you can use tex symbols in Veusz. Therefore, you can write \Omega_{DE} and \Omega_{k} for your request. See details here (Sec. 2.4 Text).

Veusz 理解一组有限的类似 LaTeX 的文本格式.有一些差异(例如，10^23"将 2 和 3 放在上标中)，但非常相似.您还应该省略美元符号.Veusz 支持上标(^")、下标(_")，分组属性的括号为{"和}".

Veusz understands a limited set of LaTeX-like formatting for text. There are some differences (for example, "10^23" puts the 2 and 3 into superscript), but it is fairly similar. You should also leave out the dollar signs. Veusz supports superscripts ("^"), subscripts ("_"), brackets for grouping attributes are "{" and "}".

支持的 LaTeX 符号包括:\AA、\Alpha、\Beta、\Chi、\Delta、\Epsilon、\Eta、\Gamma、\Iota、\Kappa、\Lambda、\Mu、\Nu、\Omega、\Omicron、\Phi、\Pi、\Psi、\Rho、\Sigma、\Tau、\Theta、\Upsilon、\Xi、\Zeta、\alpha、\approx、\ast、\asymp、\beta、\bowtie, \bullet, \cap, \c \circ, \cup, \dagger, \dashv, \ddagger, \deg, \delta, \diamond, \divide, \doteq, \downarrow, \epsilon, \equiv, \eta, \gamma, \ge, \gg, \in, \infty, \int, \iota, \kappa, \lambda, \le, \leftarrow, \lhd, \ll, \models, \mp, \mu,\neq、\ni、\nu、\odot、\omega、\omicron、\ominus、\oplus、\oslash、\otimes、\parallel、\perp、\phi、\pi、\pm、\prec、\preceq, \propto, \psi, \rhd, \rho, \rightarrow, \sigma, \sim, \simeq, \sqrt, \sqsubset, \sqsubseteq, \sqsupset, \sqsupseteq, \star, \stigma, \subset, \subseteq, \succ, \succeq, \supset, \supseteq, \tau, \theta, \times, \umid, \unlhd, \unrhd, \uparrow, \uplus, \upsilon, \vdash, \vee, \wedge,\xi, \zeta.如果需要(并且存在于 unicode 字符集中)，请请求附加字符.可以直接从字符映射中包含特殊符号.

Supported LaTeX symbols include: \AA, \Alpha, \Beta, \C \Delta, \Epsilon, \Eta, \Gamma, \Iota, \Kappa, \Lambda, \Mu, \Nu, \Omega, \Omicron, \P \Pi, \Psi, \Rho, \Sigma, \Tau, \Theta, \Upsilon, \Xi, \Zeta, \alpha, \approx, \ast, \asymp, \beta, \bowtie, \bullet, \cap, \c \circ, \cup, \dagger, \dashv, \ddagger, \deg, \delta, \diamond, \divide, \doteq, \downarrow, \epsilon, \equiv, \eta, \gamma, \ge, \gg, \in, \infty, \int, \iota, \kappa, \lambda, \le, \leftarrow, \lhd, \ll, \models, \mp, \mu, \neq, \ni, \nu, \odot, \omega, \omicron, \ominus, \oplus, \oslash, \otimes, \parallel, \perp, \p \pi, \pm, \prec, \preceq, \propto, \psi, \rhd, \rho, \rightarrow, \sigma, \sim, \simeq, \sqrt, \sqsubset, \sqsubseteq, \sqsupset, \sqsupseteq, \star, \stigma, \subset, \subseteq, \succ, \succeq, \supset, \supseteq, \tau, \theta, \times, \umid, \unlhd, \unrhd, \uparrow, \uplus, \upsilon, \vdash, \vee, \wedge, \xi, \zeta. Please request additional characters if they are required (and exist in the unicode character set). Special symbols can be included directly from a character map.

支持其他 LaTeX 命令.\"换行.这可以用于简单的表.例如，{a\b} {c\d}"在b d"上显示a c".命令 "\frac{a}{b}" 显示垂直分数 a/b.

Other LaTeX commands are supported. "\" breaks a line. This can be used for simple tables. For example "{a\b} {c\d}" shows "a c" over "b d". The command "\frac{a}{b}" shows a vertical fraction a/b.

还支持更改字体的命令.命令 "\font{name}{text}" 更改写入 name 的字体文本.如果当前字体中缺少符号，这可能很有用，例如"\font{symbol}{g}" 应该产生一个伽玛值.您可以使用\size{+2}{text}"、\size{-2}{text}"或\size{20}{text}"来增大、减小或设置字体的大小.数字以点为单位.

Also supported are commands to change font. The command "\font{name}{text}" changes the font text is written in to name. This may be useful if a symbol is missing from the current font, e.g. "\font{symbol}{g}" should produce a gamma. You can increase, decrease, or set the size of the font with "\size{+2}{text}", "\size{-2}{text}", or "\size{20}{text}". Numbers are in points.

可以更改各种字体属性:例如，\italic{some italic text}"(或使用\textit"或\emph")、\bold{some bold text}"(或使用\textbf") 和 "\underline{一些带下划线的文本}".

Various font attributes can be changed: for example, "\italic{some italic text}" (or use "\textit" or "\emph"), "\bold{some bold text}" (or use "\textbf") and "\underline{some underlined text}".

示例文本可以包括Area/\pi (10^{-23} cm^{-2})"或\pi\bold{g}".

Example text could include "Area / \pi (10^{-23} cm^{-2})", or "\pi\bold{g}".

Veusz 使用 Qt 的 unicode 支持绘制这些符号.您还可以通过从字符映射应用程序复制和粘贴来直接包含特殊字符.如果您当前的字体不包含这些符号，那么您可能会得到一个方框字符.

Veusz plots these symbols with Qt's unicode support. You can also include special characters directly, by copying and pasting from a character map application. If your current font does not contain these symbols then you may get a box character.
