    <p>I'd like to create SVG charts from a database app. However, I know nothing about creating SVG, so I'd like to start with an editor, if I can find one. This should ideally let me -</p> <p>1 - place a zoom control in the image</p> <p>2 - place a pan control in the image</p> <p>3 - do various things on mouseovers - pop up a data box, highlight chart points</p> <p>4 - create scatter and time-line charts from my own dataset, with legends, axes, and so on.</p> <p>The idea is that, once I get a basic template from the editor, I can write C code to directly generate the SVG code.</p> <p>I've spent hours looking, and I can't find any commercial or free apps that can do anything like this. "SVG editors" primarily draw circles and rectangles, which isn't much use to me. Have I missed something? It seems that SVG editor development stopped several years ago, and various editors have been discontinued. I can't even find example SVG code that does anything similar to this.</p> <p>In fact, the more I read the more it seems that I need to do this in JavaScript, rather than directly creating images (but I don't know JavaScript either). Any thoughts on which way I should go? I've looked at maybe 20 javascript libs that will do charting, but none of them seem to tick all of 1 to 3 above. I also need to overlay polylines on scatter plots, and few of them will do that. Google charts is close, but it won't do the last one.</p> <p>Oh, I've got a captive audience, and they'll upgrade their browsers if I ask nicely.</p> <p>Thanks -</p> <p>Al</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
