Labels and bounding boxes

[Hendrik S]

Hi Alexey, unfortunately I need a little support again.

It looks like a lot has changed regarding styling and size options.

1. Axis label: We use '@' to scale the axis label down a little (documentation: @ – smaller size ), but it seems the scaling factor has changed. Or is @ 'deprecated' and we should rather use option 'size -[somevalue]'?

2. The text in the bounding boxes is not vertical-center aligned anymore. I haven't found an option to control the positioning of the bounding box relative to the text (or vice versa).

    It seems that the text itself is somewhat shifted down a little. While the distance to the bottom line of the bounding box is fine, the distance to the top line seems to be too much.

Attached are a couple of images showing the previous state, the current state (with MathGL 2.4.2.1) and a diff image for two examples.

Thanks in advance,

   Hendrik

Dear Hendric,

I'm sorry for delay -- I was ill last week :(

No, the @-style still working. But axis ticks are always use default
style, and I don't remember when it was differently. You should change
font style-and-size before the axis drawing.

Don't understand this point??? Can you send an example and desired picture?

Kind regards,

No problem, hope you feeling better. :)

I have attached an image with an example side by side. 

On the left, the bounding box around the "Point" label is fine. 

On the right (which is drawn with the latest MathGL) the upper boundary of the bounding box is too high. 

The spacing between the text and the upper boundary is twice the spacing between text and lower boundary. 

Kind regards,

I see. The problem is that formal font definition have very large space above the usual text (there are very tall symbols). Now, I take the full height for simplicity that cause extra space at upper boundary.

I'll make box drawing more accurate by taking actual height of symbols inside. I hope that I'll do it at weekend or early. Thank you for the issue.

That sounds great. Thanks for the effort.

Best,

Dear Hendrik,

I've just added this feature to the SVN [rev.1592]. You can check it.

Kind regards,
