Add text to figure using mouse collapse all in pageSyntax gtext(str) gtext(str,Name,Value) t = gtext(___)Description gtext(str) inserts the text, str, at the location you select with the mouse. When you hover over the figure window, the pointer becomes a crosshair. gtext is waiting ...
The problem that I have with the text() command is that it only works for the current axis. I have a figure with dozens of axes, and just want to add some text labels to it at the end. But depending on the position of the text, it can fall in the area of anothe...
I have created an app in MATLAB R2024b that I am compiling into a standalone executable, and I would like the end user to be able to move, resize, and change the color of text on a figure. I originally used "plotedit" to move the text ...
在MATLAB中,文本的处理可以使用text对象。text对象是MATLAB中用于创建和编辑文本的一种图形对象。用户可以将文本绘制在图形窗口上的指定位置,并设置文本的字体、颜色、大小等属性。在本文中,我们将深入探讨MATLAB中text对象的使用方法及其功能。 首先,我们需要先创建一幅图像,以便将文本绘制在其上。可以使用`figure`函数...
