So even when you use view$rotate(), the text direction won't change..is this also what we expected to see?<div><br></div></blockquote></div><div><br>Yes. I can see how that may not always be desirable, but it would be tough to work around it. That is, I cannot tease out the rotation from the rest of the transformation. In the case of a word cloud, I think it would be desirable, i.e., one is thinking of the text as glyphs that are independent of the scales.<br>

<div><br></div></div><div>Yes, if you don't mind spend some time on it, it will be really nice to have a control over the text size, e.g. when I plot a sequence data, like ACTGGGC....I can resize one single character to address the mis-alignment.</div>

I will work around this to see if I have some problem. </div>
<div><br></div></div></blockquote></div><div><br>Text glyphs could be scaled differently in the horizontal and vertical. Would this help with this issue? That is, you could stretch the letters vertically.<br></div></div>

<br></div></div></blockquote><div><br><br>I added support for this.

<div><br></div></div></blockquote></div><div><br>I'm not sure I follow. Are you talking about globalPos() on the event object? That is global screen position, not even relative to the window, so you would need to be careful to adjust it.<br>

<div class="gmail_quote"><div>and I think you are right, I guess I cannot use it. I am thinking that maybe qdrawText will be faster than QToolTip, maybe tooltip is not used in this purpose to show the exon names, maybe it's designed to show widget name and function description.</div>

This is by design. If this didn't work that way, then when the user zoomed into a chromosome, for example, the text labels would get really stretched out. Glyphs are the same way (they're essentially fancy characters). Zooming into a scatterplot should not make the glyphs larger. Circles (after much debate inside my head) behave the same as glyphs. This is because their radius, like in a bubble plot, is derived from something other than the X and Y axes.<br>
<br>Shapes however, like rectangles, polygons and paths, are zoomed. You expect a mosaic plot rectangle or a map polygon to scale with the plot. <br><br></blockquote><div> </div></div><div>This make sense to me, in most cases, i guess people won't expect the circle or text to be zoomed in.</div>

Deepayan and I decided a long time ago that zooming does not behave like a "magnifying glass." It rescales the plot. <br>
<br></blockquote><div><br></div></div><div>No, you don't have to change that, it's convenient so far, I am just curious why this doesn't work for text and circle, because in other rare case, I will draw very small text as labels of axis for one circular track, or if I draw points around the circular track, I am still expecting the points will be zoomed in when I rescale the view. I guess I am confused the "rescale of the view" with the one you defined with Deepayan, but it make sense to me.</div>
<div>
<div><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">There are some ways to get around this if you really want to:<br>- Draw the text as a path.<br>
- Use the "render" method on the scene to render to a QPicture, rescale that and display it. This is how I imagined someone making a magnifying glass. QPicture is a vectorized representation, so no nasty scaling artifacts are introduced.<br>
</blockquote><div><br></div></div><div>Thanks, I think I need to do it in this way, if I really need them to be rescaled. I never try QPicture before, I will take a look at it.</div><div><div></div><div><div>
