how does one eliminate blank white space below the figure i have constructed completely across the background, reducing the top to bottom length only, without changing scale

i thought i could merely pull up the bottom of the figure

this works, but it shrinks the up/down scale of the figure

'seems it should be easy but i am flumoxed ): thanks for any suggestion

Hi Frank,

To eliminate the blank white space below a figure without changing its scale, you can try adjusting the aspect ratio or cropping the image. Here are a few suggestions:

1. Aspect Ratio Adjustment: You can modify the aspect ratio of the figure to reduce the top-to-bottom length without changing the scale. This can be done using image editing software like Photoshop or online tools. Look for options like "constrain proportions" or "maintain aspect ratio" while adjusting the image size.
2. Cropping: If the blank white space is only present at the bottom of the figure, you can crop the image to remove the unwanted space. Crop the image by selecting a region that includes the desired part of the figure and excludes the blank space. This will effectively reduce the top-to-bottom length without changing the scale.
3. Resizing: Another option is to resize the image while maintaining the aspect ratio. You can decrease the height of the image without changing the width. This will reduce the top-to-bottom length of the figure without affecting the overall scale.

Thanks so much, Shaik. How does one "select a region that includes the desired part of the figure and excludes the blank space" ? I seem to remember there is some tool that allows one to place a rectangle around a desired section, but I don't seem to find one anymore. Once one selects the region, what do you do? Thanks. :)

@Frank Lad You're welcome! Selecting a region that includes the desired part of the figure and excludes the blank space can be done using various image editing tools. The specific method might depend on the software or application you are using, but I can provide you with a general approach.

If you are working with an image editing program like Adobe Photoshop or GIMP, you can typically use the "Rectangular Marquee Tool" or a similar tool.

Thanks, Shaik. :) so I guess bottom line is that this cannot be done in mathlab. surprising.

anyhow, i'll look into adobe photoshop. thanks
